Abstract (original English)
In horses, stem cell therapies are a promising tool to the treatment of many injuries, which are common consequences of athletic endeavor, resulting in high morbidity and often compromising the performance. In spite of many advantages, the isolation of stem cells similar to human, from equine adipose tissue, occurred only recently. The aim of this study was to isolate equine adipose tissue-derived progenitor cells (eAT-PC), to characterize their proliferative potential, and to study their differentiation capacity before and after cryopreservation. The cells, isolated from horse adipose tissue, presented similar fibroblast-like cell morphology in vitro. Their proliferation rate was evaluated during 63 days (23 passages) before and after cryopreservation. After the induction of osteogenic differentiation, von Kossa staining and positive immunostaining studies revealed the formation of calcified extracellular matrix confirming the osteogenic potential of these cells. Adipogenic differentiation was induced using two protocols: routine and other one developed by us, while our protocol requires a shorter time (Oil Red O staining revealed significant accumulation of lipid droplets after 7 days). Chondrogenic differentiation was observed after 21 days of induced pellet culture, as evidenced by histological (toluidine blue) and immunohistochemistry studies. Our data demonstrate that eAT
