Topic:Histology

Histology in horses involves the microscopic examination of tissues to understand their structure and function. This field of study provides insights into the cellular composition and architecture of equine tissues, aiding in the diagnosis of diseases and the assessment of tissue health. Histological analysis is used to identify pathological changes, such as inflammation, neoplasia, or degenerative conditions, by examining tissue samples obtained through biopsies or necropsies. Common tissues studied in equine histology include skin, muscle, bone, and internal organs. This page compiles peer-reviewed research studies and scholarly articles that explore histological techniques, findings, and their applications in equine veterinary medicine.

Veterinary pathology    October 5, 2018   Volume 56, Issue 2 244-247 doi: 10.1177/0300985818806051
Piccinelli C, Jago R, Milne E.Equine dysautonomia (grass sickness) is characterized by autonomic neuronal degeneration and is often fatal. As outbreaks occur, rapid diagnosis is essential but confirmation currently requires histological examination. This study evaluated diagnostic accuracy of cytological examination of cranial cervical ganglion (CCG) scrapings for dysautonomia diagnosis. CCG smears from 20 controls and 16 dysautonomia cases were stained with May-Grünwald Giemsa (MGG), hematoxylin and eosin (HE), and cresyl fast violet (CFV), with HE-stained histological sections of CCG as gold standard for diagnosis. Exam...
Growth Factor-Mediated Tenogenic Induction of Multipotent Mesenchymal Stromal Cells Is Altered by the Microenvironment of Tendon Matrix.
Cell transplantation    September 25, 2018   Volume 27, Issue 10 1434-1450 doi: 10.1177/0963689718792203
Roth SP, Schubert S, Scheibe P, Groß C, Brehm W, Burk J.Age-related degenerative changes in tendon tissue represent a common cause for acute tendon pathologies. Although the regenerative potential of multipotent mesenchymal stromal cells (MSC) was reported to restore functionality in injured tendon tissue, cellular mechanisms of action remain partly unclear. Potential tenogenic differentiation of applied MSC is affected by various intrinsic and extrinsic factors. The current study presents an in vitro model to evaluate the combined extrinsic effects of decellularized equine tendon matrix, transforming growth factor beta 3 (TGFβ3) and bone morphoge...

Human reproduction (Oxford, England)    September 22, 2018   Volume 33, Issue 10 1829-1838 doi: 10.1093/humrep/dey276
Bernet A, Bastien A, Soulet D, Jerczynski O, Roy C, Bianchi Rodrigues Alves M, Lecours C, Tremblay MÈ, Bailey JL, Robert C, Belleannée C.Where are primary cilia (PC) organelles located during postnatal epididymal development? Our findings unveil the existence of PC sensory organelles in different epididymal cell types according to postnatal development stage. Primary cilia are sensory organelles that orchestrate major signaling pathways during organ development and homeostasis. Epididymal PC have been detected in the horses, donkey and mules but their cell-lineage specificity has never been investigated in this organ. A longitudinal study was performed by examining tissue from n = 3 to n = 10 transgenic mice at different times ...
Ultrastructural and histological characteristics of the endometrium during early embryo development in mares.
Theriogenology    September 18, 2018   Volume 123 1-10 doi: 10.1016/j.theriogenology.2018.09.018
Camozzato GC, Martinez MN, Bastos HBA, Fiala-Rechsteiner S, Meikle A, Jobim MIM, Gregory RM, Mattos RC.The aim of this study was to evaluate ultrastructural and histological changes in the endometrium on days 7, 10 and 13 post-ovulation in pregnant and cyclic mares. Mares were routinely examined by transrectal palpation and ultrasonographic examination of the reproductive tract until estrus was detected. In the first cycle, endometrial biopsies from 30 cyclic mares (Cyclic group) were collected on days 7, 10 and 13 post-ovulation. In the second cycle, the same mares were bred by a fertile stallion. At days 7, 10 and 13 post-ovulation intrauterine biopsies were collected. Immediately after sampl...

Altered mitochondrial oxidative phosphorylation capacity in horses suffering from polysaccharide storage myopathy.
Journal of bioenergetics and biomembranes    August 24, 2018   Volume 50, Issue 5 379-390 doi: 10.1007/s10863-018-9768-6
Tosi I, Art T, Cassart D, Farnir F, Ceusters J, Serteyn D, Lemieux H, Votion DM.Polysaccharide storage myopathy (PSSM) is a widely described cause of exertional rhabdomyolysis in horses. Mitochondria play a central role in cellular energetics and are involved in human glycogen storage diseases but their role has been overlooked in equine PSSM. We hypothesized that the mitochondrial function is impaired in the myofibers of PSSM-affected horses. Nine horses with a history of recurrent exercise-associated rhabdomyolysis were tested for the glycogen synthase 1 gene (GYS1) mutation: 5 were tested positive (PSSM group) and 4 were tested negative (horses suffering from rhabdomyo...
Functional anatomy of the equine temporomandibular joint: Histological characteristics of the articular surfaces and underlining tissues.
Veterinary journal (London, England : 1997)    August 13, 2018   Volume 239 35-41 doi: 10.1016/j.tvjl.2018.08.003
Adams K, Schulz-Kornas E, Arzi B, Failing K, Vogelsberg J, Staszyk C.It has been assumed that dental conditions cause disorders of the equine temporomandibular joint (TMJ), due to biomechanical overload or aberrant loading. However, the incidence of published TMJ disorders in horses is low and this leads to the question whether the equine TMJ is adapted well to its biomechanical requirements or is able to remodel its articular surfaces in response to modified loading conditions. The aim of this study was to determine the histological characteristics of healthy equine TMJs. The tissue components of the articular surfaces of 10 TMJs obtained from horses without a...
In vivo antral follicle wall biopsy: a new research technique to study ovarian function at the cellular and molecular levels.
Reproductive biology and endocrinology : RB&E    July 28, 2018   Volume 16, Issue 1 71 doi: 10.1186/s12958-018-0380-8
Ishak GM, Bashir ST, Dutra GA, Gastal GDA, Gastal MO, Cavinder CA, Feugang JM, Gastal EL.In vivo studies involving molecular markers of the follicle wall associated with follicular fluid (FF) milieu are crucial for a better understanding of follicle dynamics. The inability to obtain in vivo samples of antral follicle wall (granulosa and theca cells) without jeopardizing ovarian function has restricted advancement in knowledge of folliculogenesis in several species. The purpose of this study in mares was to develop and validate a novel, minimally invasive in vivo technique for simultaneous collection of follicle wall biopsy (FWB) and FF samples, and repeated collection from the sam...
TGF-β1 upregulates the expression of hyaluronan synthase 2 and hyaluronan synthesis in culture models of equine articular chondrocytes.
Journal of veterinary science    July 25, 2018   Volume 19, Issue 6 735-743 doi: 10.4142/jvs.2018.19.6.735
Ongchai S, Somnoo O, Kongdang P, Peansukmanee S, Tangyuenyong S.We investigated the effect of transforming growth factor beta 1 (TGF-β1) on equine hyaluronan synthase 2 () gene expression and hyaluronan (HA) synthesis in culture models of articular chondrocytes. Equine chondrocytes were treated with TGF-β1 at different concentrations and times in monolayer cultures. In three-dimensional cultures, chondrocyte-seeded gelatin scaffolds were cultured in chondrogenic media containing 10 ng/mL of TGF-β1. The amounts of HA in conditioned media and in scaffolds were determined by enzyme-linked immunosorbent assays. mRNA expression was analyzed by semi-quantita...
Effects of mesenchymal stromal cells versus serum on tendon healing in a controlled experimental trial in an equine model.
BMC musculoskeletal disorders    July 18, 2018   Volume 19, Issue 1 230 doi: 10.1186/s12891-018-2163-y
Ahrberg AB, Horstmeier C, Berner D, Brehm W, Gittel C, Hillmann A, Josten C, Rossi G, Schubert S, Winter K, Burk J.Mesenchymal stromal cells (MSC) have shown promising results in the treatment of tendinopathy in equine medicine, making this therapeutic approach seem favorable for translation to human medicine. Having demonstrated that MSC engraft within the tendon lesions after local injection in an equine model, we hypothesized that they would improve tendon healing superior to serum injection alone. Methods: Quadrilateral tendon lesions were induced in six horses by mechanical tissue disruption combined with collagenase application 3 weeks before treatment. Adipose-derived MSC suspended in serum or seru...

Limb bone histology records birth in mammals.
PloS one    June 20, 2018   Volume 13, Issue 6 e0198511 doi: 10.1371/journal.pone.0198511
Nacarino-Meneses C, Köhler M.The annual cyclicality of cortical bone growth marks (BGMs) allows reconstruction of some important life history traits, such as longevity, growth rate or age at maturity. Little attention has been paid, however, to non-cyclical BGMs, though some record key life history events such as hatching (egg-laying vertebrates), metamorphosis (amphibians), or weaning (suggested for Microcebus and the hedgehog). Here, we investigate the relationship between non-cyclical BGMs and a stressful biological event in mammals: the moment of birth. In the present study, we histologically examine ontogenetic serie...
Spatial distribution of preantral follicles in the equine ovary.
PloS one    June 13, 2018   Volume 13, Issue 6 e0198108 doi: 10.1371/journal.pone.0198108
Alves BG, Alves KA, Gastal GDA, Gastal MO, Figueiredo JR, Gastal EL.Comprehensive studies on spatial distribution of preantral follicles in the ovary are scarce. Considering that preantral follicles represent the main ovarian reserve, harvesting of these follicles is crucial for the development/use of assisted reproductive techniques. Therefore, knowledge on follicle spatial distribution can be helpful for targeting areas with richer number of preantral follicles through biopsy procedures. The aim of this study was to assess the distribution and localization of equine preantral follicles according to: (i) age, (ii) ovarian portion (lateral and intermediary) an...
Development of a new approach of immunotherapy against scorpion envenoming: Avian IgYs an alternative to equine IgGs.
International immunopharmacology    June 11, 2018   Volume 61 256-265 doi: 10.1016/j.intimp.2018.06.013
Sifi A, Adi-Bessalem S, Laraba-Djebari F.Antivenom treatment has been largely used against scorpion stings. Despite their efficacy, the use of mammalian antivenoms may cause adverse effects due to the immune system activation. IgYs from hyperimmunized laying hens against venoms could be a promising alternative to equine IgGs due to the various benefits that these antibodies can provide. Here we report the preparation of specific IgYs by immunizing laying hens with Aah (Androctonus australis hector) scorpion venom. IgYs were isolated from egg yolks by water dilution and salt precipitation methods; they were characterized by sodium dod...
Biochemical and biomechanical characterisation of equine cervical facet joint cartilage.
Equine veterinary journal    May 17, 2018   Volume 50, Issue 6 800-808 doi: 10.1111/evj.12845
O'Leary SA, White JL, Hu JC, Athanasiou KA.The equine cervical facet joint is a site of significant pathology. Located bilaterally on the dorsal spine, these diarthrodial joints work in conjunction with the intervertebral disc to facilitate appropriate spinal motion. Despite the high prevalence of pathology in this joint, the facet joint is understudied and thus lacking in viable treatment options. Objective: The goal of this study was to characterise equine facet joint cartilage and provide a comprehensive database describing the morphological, histological, biochemical and biomechanical properties of this tissue. Methods: Descriptive...
Treatment of limb wounds of horses with orf virus IL-10 and VEGF-E accelerates resolution of exuberant granulation tissue, but does not prevent its development.
PloS one    May 15, 2018   Volume 13, Issue 5 e0197223 doi: 10.1371/journal.pone.0197223
Wise LM, Bodaan CJ, Stuart GS, Real NC, Lateef Z, Mercer AA, Riley CB, Theoret CL.Bandaging of limb wounds in horses leads to formation of exuberant granulation tissue (EGT) that retards healing due to protracted inflammation, aberrant vascularisation and delayed epithelialisation. EGT is not observed if wounds are left undressed or when wounds are on the body. A previous study showed that short-term administration of proteins derived from orf virus dampened inflammation and promoted epithelialisation of open wounds in horses. Here, we investigated the impact of orf virus interleukin-10 and vascular endothelial growth factor-E on the development and resolution of EGT. Excis...
Normal microscopic anatomy of equine body and limb skin: A morphological and immunohistochemical study.
Annals of anatomy = Anatomischer Anzeiger : official organ of the Anatomische Gesellschaft    May 3, 2018   Volume 218 205-212 doi: 10.1016/j.aanat.2018.03.010
Jørgensen E, Lazzarini G, Pirone A, Jacobsen S, Miragliotta V.Information on microscopic anatomy of equine skin is sparse. In horses, limb wounds often become chronic and/or non-healing whereas body wounds heal normally. These dissimilarities in healing patterns might be a product of different phenotypic characteristics of body and limb skin. The objective of this study was to investigate microscopic anatomy, epidermal thickness, keratinocyte proliferation and differentiation as well as the presence of mast cells in normal equine skin of body and limb. Methods: The study involved body and limb skin biopsies from six horses. Histological characteristics o...

Histologic characterization of eosinophilic encephalitis in horses in Florida. Zoll WM, Prakoso D, Dark M, Liu J, Stockdale-Walden H, Long MT.Eosinophils within the central nervous system are abnormal and are usually associated with fungal or parasitic infections in horses. Causative agents include Halicephalobus gingivalis, Sarcocystis neurona, and Neospora hughesi. Confirmation of these organisms via specific testing is typically not performed, and final diagnoses are often presumptive. With molecular technology, many of these organisms can now be confirmed. This is important for emerging and zoonotic pathogens, including Angiostrongylus cantonensis, an emerging parasite of interest in the southeastern United States. We retrospect...
Use of a 3-Telsa magnet to perform delayed gadolinium-enhanced magnetic resonance imaging of the distal interphalangeal joint of horses with and without naturally occurring osteoarthritis.
American journal of veterinary research    February 22, 2018   Volume 79, Issue 3 287-298 doi: 10.2460/ajvr.79.3.287

Structure and collagen crimp patterns of functionally distinct equine tendons, revealed by quantitative polarised light microscopy (qPLM).
Acta biomaterialia    February 2, 2018   Volume 70 281-292 doi: 10.1016/j.actbio.2018.01.034
Spiesz EM, Thorpe CT, Thurner PJ, Screen HRC.Structure-function relationships in tendons are directly influenced by the arrangement of collagen fibres. However, the details of such arrangements in functionally distinct tendons remain obscure. This study demonstrates the use of quantitative polarised light microscopy (qPLM) to identify structural differences in two major tendon compartments at the mesoscale: fascicles and interfascicular matrix (IFM). It contrasts functionally distinct positional and energy storing tendons, and considers changes with age. Of particular note, the technique facilitates the analysis of crimp parameters, in w...
