In vitro culture of bone marrow mesenchymal stem cells in rats and differentiation into retinal neural-like cells.
In order to study the in vitro culture and expansion of bone marrow mesenchymal stem cells in rats (rMSCs) and the possibility of rMSCs differentiation into retinal neural cells, the bone marrow-derived cells in SD rats were isolated and cultured in vitro. The retinal neural cells in SD rats were cultured and the supernatants were collected to prepare conditioned medium. The cultured rMSCs were induced to differentiate by two steps. Immunofluorescence method and anti-nestin, anti-NeuN, anti-GFAP and anti-Thy1.1 antibodies were used to identify the cells derived from the rMSCs. The results showed that the in vitro cultured rMSCs grew well and expanded quickly. After induction with two conditioned media, rMSCs was induced to differentiate into neural progenitor cells, then into retinal neural-like cells which were positive for nestin, NeuN, GFAP and Thy1.1 detected by fluorescence method. The findings suggested that rMSCs could be culture and expanded in vitro, and induced to differentiate into retinal neural-like cells.
