Phase contrast (A, C, E) and corresponding fluorescence (B, D, F) images of encapsulated mesenchymal stem cells (C3H10T1/2 cells) cultured under different conditions: cells cultured in Dulbecco’s modified Eagle’s medium (DMEM) for 7 weeks (A, B); cells cultured in DMEM for 4 weeks and then in adipogenic differentiation medium for 3 weeks (C, D); and cells cultured in DMEM for 4 weeks and then in osteogenic differentiation medium for 3 weeks (E, F). Reproduced from reference (6). In the fluorescence images, live and dead cells were stained green and red, respectively. Scale bar: 100 µm.
