Figure 3. hUC-MSCs induced into adipocytes and osteoblasts. (A) Induced into adipocytes for 7 days and 14 days. The lipid droplets in cells were stained by Oil Red O. Scale bar=50μm. (B) Induced into osteoblasts for 7 days and 28 days. There are bright red calcium nodules stained by alizarin red in cytoplasm. Scale bar=50μm. n=3.
