Clonal Populations of Amniotic Cells by Dilution and Direct Plating: Evidence for Hidden Diversity
Figure 5
Immunostaining for vimentin and keratin. BMMSCp5, PB4A2p16, PB1C4p12 and PB3B5p11 cell populations were stained for the stromal cell marker vimentin (green), the epithelial cell marker keratin (red) and a fluorescent chromatin dye (blue). Note that virtually all PB4A2 and PB3B5 cells showed keratin staining, although the intensity varied. The clonal population of PB1C4 stromal progenitors did not show immunostaining of prominent networks of either vimentin or keratin. Scale (50 microns) is identical in all panels.
