Expression of Stem Cell Markers in the Human Fetal Kidney
Figure 3
FACS analysis of putative stem cell markers in EpCAM subpopulations.
(a) Representative zebra graph of EpCAM staining and the subpopulation gating. EpCAM subpopulations were gated according to EpCAM staining intensity (negative, dim or bright) versus FSC. (b) Representative dot plot graphs of NCAM1, PSA-NCAM, FZD7, NTRK2, CD24 and CD133 expression levels in EpCAM subpopulations of HFK. Quadrates were placed according to isotype control confiding the negative staining to the lower left quadrant. Percentage of cells in each subgroup appears on the lower right quadrant. (c) Summarizing bar graphs of NCAM1, PSA- NCAM, NTRK2, FZD7, CD24 and CD133 expression levels in EpCAM subpopulations. Data are average % of cells in each subgroup±SD. Analysis of each marker was performed at least three times.
