Fig. 2From: Detection of hepatic maturation by Raman spectroscopy in mesenchymal stromal cells undergoing hepatic differentiationThe lipochrome formation in cytoplasm increased in the MSC-derived hepatocytes and primary hepatocytes. The undifferentiated MSCs, MSC-derived hepatocytes and primary hepatocytes were stained with PAS staining. The white arrows indicate the PAS staining-positive granulesBack to article page
