Topic:Cells

The study of cells in horses encompasses the examination of various cell types and their functions within the equine body. Cells are the basic structural and functional units of life, and in horses, they contribute to numerous physiological processes, including growth, repair, and immune responses. Different cell types, such as red blood cells, white blood cells, and muscle cells, each perform specific roles that are vital for maintaining the health and homeostasis of the horse. This topic includes research on cellular mechanisms, cellular responses to disease or injury, and the application of cellular biology in equine medicine. This page compiles peer-reviewed research studies and scholarly articles that explore the structure, function, and significance of cells in equine biology and health.
Generation of equine enteroids and enteroid-derived 2D monolayers that are responsive to microbial mimics.
Veterinary research    August 14, 2021   Volume 52, Issue 1 108 doi: 10.1186/s13567-021-00976-0
Hellman S.Enteroid cultures are three-dimensional in vitro models that reflect the cellular composition and architecture of the small intestine. One limitation with the enteroid conformation is the enclosed lumen, making it difficult to expose the apical surface of the epithelium to experimental treatments. The present study was therefore conducted to generate cultures of equine enteroids and to develop methods for culture of enteroid-derived cells on a two-dimensional plane, enabling easy access to the apical surface of the epithelium. Equine enteroids were established from small intestinal crypts with...
Kinetics of Gene Expression Changes in Equine Fetal Interzone and Anlagen Cells Over 14 Days of Induced Chondrogenesis.
Frontiers in veterinary science    August 9, 2021   Volume 8 722324 doi: 10.3389/fvets.2021.722324
Mok CH, MacLeod JN.Within developing synovial joints, interzone and anlagen cells progress through divergent chondrogenic pathways to generate stable articular cartilage and transient hypertrophic anlagen cartilage, respectively. Understanding the comparative cell biology between interzone and anlagen cells may provide novel insights into emergent cell-based therapies to support articular cartilage regeneration. The aim of this study was to assess the kinetics of gene expression profiles in these skeletal cell lines after inducing chondrogenesis in culture. Interzone and anlagen cells from seven equine fetuses w...
Effects of cortisol on prostaglandin F2α secretion and expression of genes involved in the arachidonic acid metabolic pathway in equine endometrium – In vitro study.
Theriogenology    August 8, 2021   Volume 173 221-229 doi: 10.1016/j.theriogenology.2021.08.009
Szóstek-Mioduchowska AZ, Shiotani H, Yamamoto Y, Sadowska A, Wójtowicz A, Kozai K, Hojo T, Kimura K, Skarzynski DJ, Okuda K.Glucocorticoids (GCs) are known to play an important role in maintaining basal and stress-related homeostasis by interacting with endocrine mediators and prostaglandins (PGs). Although a growing body of evidence shows that GCs exert their regulatory action at a multitude of sites in the reproductive axis through corticosteroid receptors, little is known about the direct role of cortisol, an active form of GCs, in the equine endometrium. Thus, the study aimed to determine the effect of cortisol on PGF synthesis in the endometrial tissue and cells in vitro. In Exp.1, the immunolocalization and ...
Culture protocols for horse embryos after ICSI: Effect of myo-inositol and time of media change.
Animal reproduction science    July 27, 2021   Volume 233 106819 doi: 10.1016/j.anireprosci.2021.106819
Brom-de-Luna JG, Salgado RM, Felix MR, Canesin HS, Stefanovski D, Diaw M, Hinrichs K.In vitro production of horse embryos via intracytoplasmic sperm injection (ICSI) is a useful clinical and research technique. Current rates of blastocyst production are typically sub-optimal, and few methods to increase the rate of equine blastocyst development have been reported. Factors that might improve blastocyst production in a horse embryo culture system were explored. Myo-inositol is found in the horse oviduct and improves blastocyst development in other species, thus Experiment 1 was conducted to assess the effect of 10 mM myo-inositol added to Day 0-5 embryo culture medium, using hor...
Increased fibroblast accumulation in the equine heart following persistent atrial fibrillation.
International journal of cardiology. Heart & vasculature    July 20, 2021   Volume 35 100842 doi: 10.1016/j.ijcha.2021.100842
Saljic A, Friederike Fenner M, Winters J, Flethøj M, Eggert Eggertsen C, Carstensen H, Dalgas Nissen S, Melis Hesselkilde E, van Hunnik A....Fibroblasts maintain the extracellular matrix homeostasis and may couple to cardiomyocytes through gap junctions and thereby increase the susceptibility to slow conduction and cardiac arrhythmias, such as atrial fibrillation (AF). In this study, we used an equine model of persistent AF to characterize structural changes and the role of fibroblasts in the development of an arrhythmogenic substrate for AF. Methods: Eleven horses were subjected to atrial tachypacing until self-sustained AF developed and were kept in AF for six weeks. Horses in sinus rhythm (SR) served as control. In terminal open...
Establishment of a Three-Dimensional In Vitro Model of Equine Papillomavirus Type 2 Infection.
Viruses    July 19, 2021   Volume 13, Issue 7 1404 doi: 10.3390/v13071404
Ramsauer AS, Wachoski-Dark GL, Fraefel C, Ackermann M, Brandt S, Grest P, Knight CG, Favrot C, Tobler K.There is growing evidence that equine papillomavirus type 2 (EcPV2) infection is etiologically associated with the development of genital squamous cell carcinoma (SCC) and precursor lesions in equids. However, the precise mechanisms underlying neoplastic progression remain unknown. To allow the study of EcPV2-induced carcinogenesis, we aimed to establish a primary equine cell culture model of EcPV2 infection. Three-dimensional (3D) raft cultures were generated from equine penile perilesional skin, plaques and SCCs. Using histological, molecular biological and immunohistochemical methods, rafts...

Animals : an open access journal from MDPI    July 16, 2021   Volume 11, Issue 7 2121 doi: 10.3390/ani11072121
Porcellato I, Mecocci S, Brachelente C, Cappelli K, Armando F, Tognoloni A, Chiaradia E, Stefanetti V, Mechelli L, Pepe M, Gialletti R, Passeri B....In horses, penile squamous cell carcinomas (epSCCs) are among the most common cutaneous neoplastic lesions. These tumors usually arise in benign lesions such as viral plaques and papillomas frequently induced by papillomavirus type 2 (EcPV2) infection. In the last decade, the introduction of immune checkpoint inhibitors (ICI) for the treatment of human cancers has demonstrated promising results. Among the most commonly targeted pathways, there is PD-1/PD-L1 and CTLA-4. The aim of this study is to investigate the expression of the PD-1/PD-L1 pathway and CTLA-4 in the tumor microenvironment of ...
Regulatory T cells provide chondroprotection through increased TIMP1, IL-10 and IL-4, but cannot mitigate the catabolic effects of IL-1β and IL-6 in a tri-culture model of osteoarthritis.
Osteoarthritis and cartilage open    July 16, 2021   Volume 3, Issue 3 100193 doi: 10.1016/j.ocarto.2021.100193
Keller LE, Tait Wojno ED, Begum L, Fortier LA.To gain insight into Treg interactions with synovial tissues in early OA, an equine tri-culture model of OA was used to test the hypothesis that Tregs, in the absence of T Helper 17 ​cells, are sufficient to resolve inflammation elicited by IL-1β. Unassigned: To model normal and OA joints, synoviocytes were co-cultured with chondrocytes in a transwell system and ± stimulated with IL-1β. Tregs were activated and enriched, then added to co-cultures, creating tri-cultures. At culture end, synoviocytes and chondrocytes were analyzed for gene expression, Treg Foxp3 expression was reexamined b...
Light and electron-microscopic localization of CD9 and surfactant protein A and D in normal lungs of the horse. Bocking T, Singh B.The lung is a complex organ, and its physiology and immunology are regulated by various immune molecules and cells. Lung surfactant, a mixture of phospholipids and proteins produced by the bronchiolar and type II alveolar epithelial cells, is one such important player in lung physiology. Compared to knowledge about the biology of the surfactant in rodents and humans, only limited data are available on the surfactant in the horse. Although there are data linking levels of surfactant proteins with respiratory disease in the horse, there are no data on the cellular localization of surfactant prot...
Application across species of a one health approach to liquid sample handling for respiratory based -omics analysis.
Scientific reports    July 12, 2021   Volume 11, Issue 1 14292 doi: 10.1038/s41598-021-93839-9
Karagianni AE, Eaton SL, Kurian D, Cillán-Garcia E, Twynam-Perkins J, Raper A, Wishart TM, Pirie RS.Airway inflammation is highly prevalent in horses, with the majority of non-infectious cases being defined as equine asthma. Currently, cytological analysis of airway derived samples is the principal method of assessing lower airway inflammation. Samples can be obtained by tracheal wash (TW) or by lavage of the lower respiratory tract (bronchoalveolar lavage (BAL) fluid; BALF). Although BALF cytology carries significant diagnostic advantages over TW cytology for the diagnosis of equine asthma, sample acquisition is invasive, making it prohibitive for routine and sequential screening of airway ...
Cancer of unknown primary in a mare: case report and comparative pathology review. Brinker EJ, Ceriotti S, Naskou MC, Spangler EA, Groover ES, Neto RLALT.A 25-y-old Percheron mare was admitted to the teaching hospital because of lethargy and intractable dyspnea. Thoracoabdominal ultrasound examination identified severe peritoneal effusion, mild bilateral pleural effusion, and a diffuse pulmonary nodular pattern. Cytology of peritoneal fluid revealed a hypercellular sample with clusters of neoplastic polygonal cells and admixed macrophages. Euthanasia was followed by postmortem examination; marked bi-cavitary effusion was present, and innumerable up to 4-cm diameter, round-to-floriform nodules were diffusely evident throughout serosal surfaces a...

The aim of this study was to perform a morphometric analysis of His bundle characteristics of in humans, dogs, horses and pigs and compare them in these studied species. Histological sections of 5 μm thickness were obtained and stained with hematoxylin-eosin and Masson's trichrome; the desmin and periodic acid-Schiff methods were also used for precise identification of cells. The His bundle was found...
Glial Fibrillary Acidic Protein and Ionized Calcium-Binding Adapter Molecule 1 Immunostaining Score for the Central Nervous System of Horses With Non-suppurative Encephalitis and Encephalopathies.
Frontiers in veterinary science    July 9, 2021   Volume 8 660022 doi: 10.3389/fvets.2021.660022
Boos GS, Failing K, Colodel EM, Driemeier D, de Castro MB, Bassuino DM, Diomedes Barbosa J, Herden C.Like humans, horses are susceptible to neurotropic and neuroinvasive pathogens that are not always readily identified in histological sections. Instead, alterations in astrocytes and microglia cells can be used as pathological hallmarks of injured nervous tissue in a variety of infectious and degenerative diseases. On the other hand, equine glial cell alterations are poorly characterized in diseases. Therefore, in this study, we provide a statistically proved score system to classify astrogliosis and microgliosis in the central nervous system (CNS) of horses, based on morphological and quantit...
The Rho kinase (ROCK) inhibitor Y-27632 reduces the β2-adrenoceptor density but enhance cAMP formation in primary equine bronchial epithelial cells.
European journal of pharmacology    July 8, 2021   Volume 907 174323 doi: 10.1016/j.ejphar.2021.174323
Schellenberg LM, Regenthal R, Abraham G.The present study addresses the effect of the Rho-kinase (ROCK) inhibitor Y-27632 on the β-adrenoceptor density and β-agonist-stimulated intracellular second messenger cAMP formation in primary equine bronchial epithelial cells (EBEC). Y-27632 significantly decreased the β-adrenoceptor number (B) without markedly affecting the receptor affinity (dissociation constant, K) to the radioligand [I]-iodocyanopindolol (ICYP). In contrast, Y-27632 augmented the β-agonist-stimulated intracellular cAMP production. Herein, Y-27632 markedly increased the maximal cAMP responses (E) (isoproterenol >...
Characterization of an Ex Vivo Equine Endometrial Tissue Culture Model Using Next-Generation RNA-Sequencing Technology.
Animals : an open access journal from MDPI    July 3, 2021   Volume 11, Issue 7 doi: 10.3390/ani11071995
Monteiro de Barros MR, Davies-Morel MCG, Mur LAJ, Creevey CJ, Alison RH, Nash DM.Persistent mating-induced endometritis is a major cause of poor fertility rates in the mare. Endometritis can be investigated using an ex vivo equine endometrial explant system which measures uterine inflammation using prostaglandin F2α as a biomarker. However, this model has yet to undergo a wide-ranging assessment through transcriptomics. In this study, we assessed the transcriptomes of cultured endometrial explants and the optimal temporal window for their use. Endometrium harvested immediately post-mortem from native pony mares (n = 8) were sampled (0 h) and tissue explants were cultured ...
Factors affecting intracellular calcium influx in response to calcium ionophore A23187 in equine sperm.
Andrology    June 23, 2021   Volume 9, Issue 5 1631-1651 doi: 10.1111/andr.13036
Sampaio B, Ortiz I, Resende H, Felix M, Varner D, Hinrichs K.Exposure to the calcium ionophore A23187 may present a "universal" sperm treatment for IVF, as it bypasses capacitation pathways. However, success in utilizing A23187 is variable, especially in equine spermatozoa. Notably, albumin is used during A23187 treatment but paradoxically is thought to suppress A23187 action. Essentially no critical data are available on the effects of A23187 and albumin concentrations, ratios, or addition protocols on changes in intracellular calcium ([Ca] ) in any cell type. To determine factors that affect the action of A23187 on [Ca] in equine and murine spermatozo...

Roth SP, Brehm W, Troillet A.Cell-based therapies for the treatment of osteoarthritis in equine patients experienced a real boom within the last few years. In every day medical practice, attending veterinary surgeons extract patient's blood or other autologous tissue samples and process the material for the purpose of administering the resulting product to the same patient under their own responsibility. Although being consistently classified as treatment option within the framework of regenerative medicine, the manufacturing processes, ingredients, and mechanisms of action remain highly diverse among cell-based therapies...
Localisation of Cannabinoid and Cannabinoid-Related Receptors in the Horse Ileum.
Journal of equine veterinary science    June 16, 2021   Volume 104 103688 doi: 10.1016/j.jevs.2021.103688
Galiazzo G, Tagliavia C, Giancola F, Rinnovati R, Sadeghinezhad J, Bombardi C, Grandis A, Pietra M, Chiocchetti R.Colic is a common digestive disorder in horses and one of the most urgent problems in equine medicine. A growing body of literature has indicated that the activation of cannabinoid receptors could exert beneficial effects on gastrointestinal inflammation and visceral hypersensitivity. The localisation of cannabinoid and cannabinoid-related receptors in the intestine of the horse has not yet been investigated. The purpose of this study was to immunohistochemically localise the cellular distribution of canonical and putative cannabinoid receptors in the ileum of healthy horses. Distal ileum spec...
Presence of surfactant proteins in the uteri and placentae of pregnant mares.
The Journal of veterinary medical science    June 15, 2021   Volume 83, Issue 7 1167-1172 doi: 10.1292/jvms.20-0174
Araki M, Ohtaki T, Kimura J, Hobo S, Taya K, Tsunoda N, Taniyama H, Tsumagari S, Nambo Y.Immunohistochemical investigations of the expression of surfactant protein A (SP-A) and surfactant protein D (SP-D) in the uterine and placental tissues of 13 pregnant mares were performed using anti-horse monoclonal primary antibodies. Strong positive reactions for both SP-A and SP-D were observed in the trophoblasts in the microcotyledons of the placentae at 182 to 314 days of gestation; in uterine glandular epithelial cells, faint-to-weak reactions were observed during gestation. This study describes, for the first time, the changes in the SP-A and SP-D expression levels in the endometrium ...
Species variations in tenocytes’ response to inflammation require careful selection of animal models for tendon research.
Scientific reports    June 14, 2021   Volume 11, Issue 1 12451 doi: 10.1038/s41598-021-91914-9
Oreff GL, Fenu M, Vogl C, Ribitsch I, Jenner F.For research on tendon injury, many different animal models are utilized; however, the extent to which these species simulate the clinical condition and disease pathophysiology has not yet been critically evaluated. Considering the importance of inflammation in tendon disease, this study compared the cellular and molecular features of inflammation in tenocytes of humans and four common model species (mouse, rat, sheep, and horse). While mouse and rat tenocytes most closely equalled human tenocytes' low proliferation capacity and the negligible effect of inflammation on proliferation, the wound...
Tenogenic Potential of Equine Fetal Mesenchymal Stem Cells Under The In Vitro Effect of Bone Morphogenetic Protein-12 (BMP-12).
Journal of equine veterinary science    June 11, 2021   Volume 104 103681 doi: 10.1016/j.jevs.2021.103681
Oliva R, Núñez I, Segunda MN, Peralta OA.Equine adult bone marrow-derived MSCs (BM-MSCs) may be induced into the tenogenic lineage after exposure with bone morphogenetic protein-12 (BMP-12). Despite fetal BM-MSCs have showed a greater differentiation potential compared to adults, the tenogenic differentiation capacity of equine fetal BM-MSC have not been reported. Thus, the aim of the present study was to evaluate the in vitro tenogenic differentiation potential of equine fetal BM-MSCs under the effect of BMP-12. Equine fetal BM-MSCs were exposed to three concentrations of BMP-12 (25, 50 and 100 ng/mL) during a 21-day culture period....

International journal of implant dentistry    June 11, 2021   Volume 7, Issue 1 60 doi: 10.1186/s40729-021-00336-9
Di Stefano DA, Vinci R, Capparè P, Gherlone EF.Enzyme-deantigenic equine bone (EDEB) is a substitute of autogenous bone. Mixing it with plasma rich in growth factors (PRGF) seems a viable option to achieve enhanced bone formation in alveolar bone augmentation surgeries. This retrospective study aims to first report the histomorphometric and clinical outcomes achieved when using the EDEB/PRGF mixture for performing sinus augmentation procedures followed by delayed implant placement. Records of 11 patients who underwent 14 sinus augmentation surgeries using EDEB/PRGF followed by delayed implant placement were retrospectively collected and an...
New mAbs facilitate quantification of secreted equine TNF-α and flow cytometric analysis in monocytes and T cells.
Veterinary immunology and immunopathology    June 10, 2021   Volume 238 110284 doi: 10.1016/j.vetimm.2021.110284
Schnabel CL, Babasyan S, Freer H, Larson EM, Wagner B.Tumor necrosis factor-α (TNF-α) is a pleiotropic cytokine, that is involved in acute inflammation and is employed as a biomarker of inflammatory diseases in several species for which reliable quantification is available. We aimed to develop suitable tools to quantify TNF-α in equine samples. We generated two new mAbs against equine TNF-α (clones 48 and 292), evaluated their specificity for this cytokine, and confirmed detection of native TNF-α in stimulated equine PBMC. The TNF-α mAbs were paired in a fluorescent bead-based assay for quantification of equine TNF-α. The TNF-α assay had ...
Sperm migration, selection, survival, and fertilizing ability in the mammalian oviduct†.
Biology of reproduction    June 1, 2021   Volume 105, Issue 2 317-331 doi: 10.1093/biolre/ioab105
Mahé C, Zlotkowska AM, Reynaud K, Tsikis G, Mermillod P, Druart X, Schoen J, Saint-Dizier M.In vitro fertilization (IVF) gives rise to embryos in a number of mammalian species and is currently widely used for assisted reproduction in humans and for genetic purposes in cattle. However, the rate of polyspermy is generally higher in vitro than in vivo and IVF remains ineffective in some domestic species like pigs and horses, highlighting the importance of the female reproductive tract for gamete quality and fertilization. In this review, the way the female environment modulates sperm selective migration, survival, and acquisition of fertilizing ability in the oviduct is being considered...
Action of Carvacrol on Parascaris sp. and Antagonistic Effect on Nicotinic Acetylcholine Receptors.
Pharmaceuticals (Basel, Switzerland)    May 26, 2021   Volume 14, Issue 6 505 doi: 10.3390/ph14060505
Trailovic SM, Rajkovic M, Marjanovic DS, Neveu C, Charvet CL. sp. is the only ascarid parasitic nematode in equids and one of the most threatening infectious organisms in horses. Only a limited number of compounds are available for treatment of horse helminthiasis, and sp. worms have developed resistance to the three major anthelmintic families. In order to overcome the appearance of resistance, there is an urgent need for new therapeutic strategies. The active ingredients of herbal essential oils are potentially effective antiparasitic drugs. Carvacrol is one of the principal chemicals of essential oil from , , , , and herbs. However, the antiparasi...
Equine Hoof Stem Progenitor Cells (HPC) CD29 + /Nestin + /K15 + - a Novel Dermal/epidermal Stem Cell Population With a Potential Critical Role for Laminitis Treatment.
Stem cell reviews and reports    May 26, 2021   Volume 17, Issue 4 1478-1485 doi: 10.1007/s12015-021-10187-x
Marycz K, Pielok A, Kornicka-Garbowska K.Laminitis is a life threating, extremely painful and frequently recurrent disease of horses which affects hoof structure. It results from the disruption of blood flow to the laminae, contributing to laminitis and in severe separation of bone from the hoof capsule. Still, the pathophysiology of the disease remains unclear, mainly due to its complexity. In the light of the presented data, in the extremally difficult process of tissue structure restoration after disruption, a novel type of progenitor cells may be involved. Herein, we isolated and performed the initial characterization of stem pro...
Peripheral blood basophils are the main source for early interleukin-4 secretion upon in vitro stimulation with Culicoides allergen in allergic horses.
PloS one    May 26, 2021   Volume 16, Issue 5 e0252243 doi: 10.1371/journal.pone.0252243
Raza F, Babasyan S, Larson EM, Freer HS, Schnabel CL, Wagner B.Interleukin-4 (IL-4) is a key cytokine secreted by type 2 T helper (Th2) cells that orchestrates immune responses during allergic reactions. Human and mouse studies additionally suggest that basophils have a unique role in the regulation of allergic diseases by providing initial IL-4 to drive T cell development towards the Th2 phenotype. Equine Culicoides hypersensitivity (CH) is a seasonal immunoglobulin E (IgE)-mediated allergic dermatitis in horses in response to salivary allergens from Culicoides (Cul) midges. Here, we analyzed IL-4 production in peripheral blood mononuclear cells (PBMC) o...
Heterotopic autotransplantation of equine ovarian tissue using intramuscular versus subvulvar grafting sites: Preliminary results.
Theriogenology    May 20, 2021   Volume 172 123-132 doi: 10.1016/j.theriogenology.2021.05.015
Alves BG, Alves KA, Hyde KA, Aguiar FLN, Souza SS, Brandão FAS, Garcia EC, Pinto Y, Gastal MO, Figueiredo JR, Teixeira DIA, Gastal EL.Ovarian tissue transplantation (OTT) is a technique well established and successfully applied in humans using mainly orthotopic or heterotopic transplantation sites. In livestock, OTT is still in its infancy and, therefore, different aspects of the technique, including the efficiency of different heterotopic OTT sites as well as the potential effect of age (i.e., young vs. old mares) in the ovarian graft quality, need to be investigated. The present study investigated the efficacy of the intramuscular (IM) or the novel subvulvar mucosa (SV) heterotopic autotransplantation sites to maintain the...
Evaluation of mare endometrial cytology using the novel cytotape technique.
Animal reproduction science    May 18, 2021   Volume 230 106770 doi: 10.1016/j.anireprosci.2021.106770
Ibrahim M, Ferrer MS, Ellerbrock RE, Rollin E.The cytobrush is considered the method of choice to obtain endometrial samples. Rigid brush fibers, however, may induce endometrial irritation and bleeding, or cell fragmentation, decreasing quality and diagnostic value of the samples. It was hypothesized that samples collected using a novel cytotape would provide sample smears of greater quality and less blood contamination than the cytobrush. Endometrial samples were collected with a cytotape and a cytobrush from ten mares without endometritis. Endometritis was then induced with artificial insemination, and samples were again collected 6 h a...
The effect of ischaemic postconditioning on mucosal integrity and function in equine jejunal ischaemia.
