Identification of mesenchymal stem cell transdifferentiation into hepatocytes. Hepatocytes were used as positive control. A: Fluorescence immunostaining detection of α-fetoprotein (AFP) expression after 21 d induction in mesenchymal stem cells (MSCs) (10 × 40 magnification); B: Fluorescence immunostaining detection of albumin expression after 21 d induction in MSCs (10 × 40 magnification); C: Reverse transcription polymerase chain reaction detection of hepatocyte specific protein AFP, albumin and cytokeratin 18 (CK18) mRNA expression after 7, 14 and 21 d induction in MSCs. Scale bars represents 100 mm.
