Figure 2From: Substrate-dependent gene regulation of self-assembled human MSC spheroids on chitosan membranesPhenotype of MSCs grown on CS or TCPS. (A) The morphologies of MSCs on CS or TCPS after 16 h, 24 h and 72 h. (B) The cell viability of MSC spheroids on CS after 24 h analyzed by flow cytometry. The percentage of cells without being stained by PI was defined as the cell viability.Back to article page
