Figure 2. Photomicrographs by IPCM showing themorphological features and proliferation of cultured undifferentiated BM-MSCs: (a) Undifferentiated BM-MSCs appeared as few clusters of spindle shaped cells after 4 days of cultivation (Scale bar = 500µm).(b) Higher magnification of the white square shows spindle shaped cells at the same day (Scale bar = 100µm).(c) Colony size expanded within 14 days of cultivation, and the cells arranged in a swirling pattern (Scale bar = 500µm).(d) Highly crowded bipolar fibroblast BM-MSCs at 21 days of primary culture (Scale bar = 500µm)
