Isolation and differentiation of endometrial mesenchymal stem cells from Arabian mares.

This study aimed to extract and isolate endometrial stromal cells from Arabian mares and investigate their growth and differentiation potential. Endometrial biopsies were obtained from three healthy 6-year-old Arabian mares using a standardized, minimally invasive protocol. The isolated cells were characterized using flow cytometry and differentiation analysis. Flow cytometry revealed mesenchymal markers CD90 (95.2%) and CD105 (97.4%) and hematopoietic markers CD34 (1.17%) and CD45 (0.339%). The cells exhibited differentiation potential into adipocytes, osteoblasts, and chondrocytes. The findings suggest that endometrial cells from Arabian mares represent a promising autologous source of MSCs, particularly suited for regenerative applications in musculoskeletal disorders.
