Phenotypic characterization of mMAPC differentiation to hepatocyte-like cells. The mMAPCs were cultured on Matrigel at 21.5 × 103 cells/cm2 with FGF-4 and HGF for 4–14 days. Immunohistochemical localization of (a–c) CK18-FITC and HNF-3β-Cy3, (d–f) albumin-FITC and GATA4-Cy3, (g–i) αFP-FITC and HNF-1α-Cy3, on day 4, 7, and 14, and (j–l) CK18-FITC and albumin-Cy3 on day 14. Scale bar, 20 μm. Representative example of seven experiments.
