| Figure 2: Differentiation ability of HAPCs in vitro. Contribution of HAPCs to chimeric embryoid bodies (EBs) composed of ddy mouse ESCs and EGFP transfected HAPCs were confirmed by histological preparation. a) Chimeric embryoid bodies (phase contrast) b) Large contribution of HAPCs was observed by fluorescent microscopy. c),d) Blood vessels and blood cells e),f) Skin and cartilage. Positive immuno-reactibility with antibody against EGFP was examined under fluorescent microscope. Magnification in a,b) ×200 and in c to f) ×400. |
