From: BMP2 gene delivery to bone mesenchymal stem cell by chitosan-g-PEI nonviral vector

Figure 4

Transfection efficiency of chitosan-g-PEI in bone marrow stem cells (BMSC). The extracted BMSC were capable of conducting the osteogenic, adipogenic, and chondrogenic differentiation by Alizarin Red S, Oil Red O and toluidine blue staining (A). ZsGreen1 GFP expression in BMSC delivered by gene carriers was visualized by fluorescence and quantified by flow cytometry (B). Scale bar:100 μm.
