Fig. 1From: Antitumor effect of IL-12 gene-modified bone marrow mesenchymal stem cells combined with Fuzheng Yiliu decoction in an in vivo glioma nude mouse modelCell morphology of primary cultured BMSCs at different time points (magnification, × 400). BMSCs were cultured in vitro and adherent growth (primary culture) was observed over a period of 24 h. The cells slowly became round, fusiform and triangular in appearance from 2 days and/or 7 days compared with those from the second generation. Thereafter, the cells proliferated substantially and several spindle-shaped cells appeared. BMSCs, bone marrow mesenchymal stem cellsBack to article page
