FACS analysis of single putative stem cell surface markers in HFK cells.

<p>(a) Representative flow-cytometry histograms of surface marker molecules (green) EpCAM, NCAM1, FZD7, NTRK2, CD90, CD34, CD24, CD133, and their respective isotype controls (red) in HFK (19 weeks of gestation). (b) Summarizing bar graph of single marker staining in HFK (15–19 weeks of gestation). Each marker was tested on at least 3 independent samples. Data were calculated as average % of expressing cell±SD. Each marker was tested in 10 HFK.
