Expression of Stem Cell Markers in the Human Fetal Kidney
Figure 4
FACS analysis of putative stem cell markers in NCAM/EpCAM subpopulations.
(a) Representative dot plot graphs of EpCAM staining. Cells were gated in two groups: EpCAM negative (neg) and EpCAM positive (pos) versus FSC. (b) Representative dot plot graphs of PSA- NCAM, FZD7, NTRK2, CD24 and CD133 co-staining with NCAM in EpCAM positive or negative populations of mid-gestation HFK. Quadrates were placed according to the isotype control confiding the negative staining to the lower left quadrant. Percentage of cells for each quadrant appears in the quadrant. (c) Representative dot plot graphs of CD24 and CD133 co-staining in EpCAM subpopulations of HFK. Quadrates were placed according to the isotype control confiding the negative staining to the lower left quadrant. Percentage of cells for each marker combination appears in the quadrant. (d) Summarizing bar graphs of CD24 and CD133 co-staining in EpCAM Subpopulations. Data are average % of cells in each subgroup±SD. Analysis of each marker was performed at least three times.
