Figure 4.
Morphological transition of BM-MSCs into hepatocyte-like cells after 3 weeks. Each group was induced for 21 days and observed under a microscope. A, B, and C show HIM, HIM/HCS, and HCCS groups, respectively. a, b, and c show induction time intervals (day 1, day 13, and day 20, respectively). Scale bars = 200 µm.
