摘要

Mesenchymal stem cells (MSCs) are used extensively in cell therapy for repair and regeneration of several organs and tissues. Cell therapy is a valuable option to treat neurodegenerative diseases and MSCs have been shown to improve neuronal function through direct differentiation or secretion of neurotrophic factors. In the present study, we isolated and characterized stem cells from medial and central orbital adipose tissue and found that they could be grown in a monolayer culture. The orbital adipose tissue-derived cells were identical to bone marrow-derived MSCs in their cell surface marker expression, gene expression and multilineage differentiation abilities. The orbital adipose-derived MSCs (OAMSCs) express several neurotrophic factors, possess neuroectodermal differentiation ability and secreted factors from OAMSCs abrogated neuronal cell damage induced by oxidative stress. Thus, OAMSCs might be a valuable cell source for treatment of neurological diseases and to reverse oxidative damage in the neuronal cells.
