Use of mesenchymal stem cells or autologous conditioned serum to modulate the inflammatory response to spermatozoa in mares.

Abstract: Current treatments for Persistent mating-induced endometritis such as uterine lavage and oxytocin therapy focus on aiding the uterus in removal of inflammatory products, but these treatments do not modulate the inciting inflammatory response. Biological treatments, such as autologous conditioned serum (ACS) and mesenchymal stem cells (MSCs), have been used in human and veterinary medicine for immunomodulation for over 10 years. The objectives of this project were to evaluate the ability of ACS or MSCs to modulate the inflammatory response to spermatozoa after breeding. Two experiments were performed with six normal mares in each study to evaluate the effects of intrauterine administration of ACS, dexamethasone, or a placebo (experiment 1), or allogeneic MSCs or a placebo (experiment 2) on the inflammatory response to spermatozoa using clinical and biochemical endpoints. Treatment with ACS and MSCs significantly (P < 0.05) reduced the number of neutrophils in the uterine lumen 6 hours after the sperm challenge. An increase (P < 0.05) in the anti-inflammatory cytokine IL-1Ra was observed after treatment with MSCs before exposure to spermatozoa. There was no difference in IL-1Ra concentration in mares treated with ACS, dexamethasone, or a placebo. Mesenchymal stem cells and ACS were able to modulate the immune response to spermatozoa in normal mares. The effect may be due to an increase in IL-1Ra in MSCs-treated mares, but other bioactive molecules may be responsible for the decrease in neutrophils in ACS-treated mares. Autologous conditioned serum and bone-derived culture expanded MSCs were able to modulate the uterine inflammatory response to spermatozoa in normal mares. Treatment with allogeneic stem cells may be beneficial if a similar modulation in inflammatory cytokines occurs in mares affected by persistent mating-induced endometritis.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

This study researched the effectiveness of autologous conditioned serum (ACS) and mesenchymal stem cells (MSCs) in mitigating the inflammatory response to spermatozoa in normal mares. The study found that treatments with ACS and MSCs both lead to significant reductions in neutrophils in the uterine lumen and increased the anti-inflammatory cytokine IL-1Ra.

Objectives of the Study

  • The main purpose of this research was to examine whether autologous conditioned serum (ACS) or mesenchymal stem cells (MSCs) had the ability to modulate the inflammatory response to spermatozoa after breeding in mares.
  • The study aimed to provide alternative and more effective treatment methods for Persistent Mating-Induced Endometritis, which affects mares.

Methodology

  • Two distinct experiments were carried out involving six mares each. The study aimed to evaluate the outcomes of intrauterine administration of ACS, dexamethasone, or a placebo in one experiment, and allogeneic MSCs or a placebo in another.
  • The resulting inflammatory response to spermatozoa was measured using both clinical and biochemical endpoints.

Key Findings

  • Treatment with both ACS and MSCs significantly (P < 0.05) led to a reduction in the number of neutrophils in the uterine lumen six hours following the sperm challenge.
  • An increase in the levels of the anti-inflammatory cytokine IL-1Ra was registered after mares received treatment with MSCs prior to exposure to spermatozoa.
  • No difference was observed in IL-1Ra concentration when the mares were treated with ACS, dexamethasone, or a placebo.
  • ACS and MSCs were reported to be capable of controlling the immune response to spermatozoa in normal mares, an effect that could be attributed to the increase in IL-1Ra in the mares treated with MSCs.

Conclusions and Implications

  • The study concluded that both autologous conditioned serum (ACS) and bone-derived culture expanded MSCs succeeded in regulating the uterine inflammatory response to spermatozoa in normal mares.
  • The research suggests that treatment with allogeneic stem cells may prove beneficial if there is a similar modulation in inflammatory cytokines in mares suffering from persistent mating-induced endometritis.
