Abstract
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.
