Assessment of regeneration in meniscal lesions by use of mesenchymal stem cells derived from equine bone marrow and adipose tissue.

Abstract: OBJECTIVE To assess the ability to regenerate an equine meniscus by use of a collagen repair patch (scaffold) seeded with mesenchymal stem cells (MSCs) derived from bone marrow (BM) or adipose tissue (AT). SAMPLE 6 female Hispano-Breton horses between 4 and 7 years of age; MSCs from BM and AT were obtained for the in vitro experiment, and the horses were subsequently used for the in vivo experiment. PROCEDURES Similarities and differences between MSCs derived from BM or AT were investigated in vitro by use of cell culture. In vivo assessment involved use of a meniscus defect and implantation on a scaffold. Horses were allocated into 2 groups. In one group, defects in the medial meniscus were treated with MSCs derived from BM, whereas in the other group, defects were treated with MSCs derived from AT. Defects were created in the contralateral stifle joint but were not treated (control samples). RESULTS Both types of MSCs had universal stem cell characteristics. For in vivo testing, at 12 months after treatment, treated defects were regenerated with fibrocartilaginous tissue, whereas untreated defects were partially repaired or not repaired. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that MSCs derived from AT could be a good alternative to MSCs derived from BM for use in regenerative treatments. Results also were promising for a stem cell-based implant for use in regeneration in meniscal lesions. IMPACT FOR HUMAN MEDICINE Because of similarities in joint disease between horses and humans, these results could have applications in humans.

This research explored the use of mesenchymal stem cells from equine bone marrow and adipose tissue in the regeneration of meniscus lesions in horses. The study concluded that both types of stem cells are effective in repairing damaged meniscus and that adipose tissue could be a viable alternative to bone marrow for this kind of regenerative treatment.

Objective

  • The main objective of the study was to evaluate the potential of regenerating an equine meniscus using a collagen repair patch seeded with mesenchal stem cells derived from bone marrow and adipose tissue. This was accomplished through both in vitro and in vivo experiments.

Sample and Procedures

  • The research was conducted on 6 female Hispano-Breton horses aged between 4 and 7 years. The researchers took samples of MSCs from the bone marrow and adipose tissue for in vitro experiments, before utilizing the horses in the in vivo experiment.
  • The in vitro experiment looked into the similarities and differences of MSCs derived from bone marrow and adipose tissue through cell culture.
  • For the in vivo assessment, the researchers created a meniscus defect and implanted it on a scaffold. The horses were split into two groups. One group’s defects were treated with MSCs sourced from the bone marrow, whilst the other group’s defects were treated with MSCs sourced from adipose tissue. Defects were also created in the contralateral stifle joint, which were left untreated to serve as control samples.

Results

  • Findings showed that both types of MSCs shared universal stem cell characteristics. The study found that, a year after treatment, the treated defects had regenerated with fibrocartilaginous tissue. In contrast, the untreated defects were either partially repaired or not repaired at all.
  • The study concluded that MSCs derived from adipose tissue could be an effective alternative to MSCs derived from bone marrow for regenerative treatment practices, opening up a new potential avenue for stem cell therapies.

Impact for Human Medicine

  • Given that joint disease in horses and humans share common features, the findings from this study could have potential applications in human medicine, specifically in the field of regenerative medicine and therapies associated with meniscus lesions.
