Characterization of Cardiac-Resident Progenitor Cells Expressing High Aldehyde Dehydrogenase Activity

Figure 4

Flow cytometric analysis of the expression of cell-surface antigen markers in freshly isolated nonmyocytic cardiac cells from 8-week-old mice. Data are percentages (mean, SD) of positive cells for the indicated markers, subdivided into three groups: those significantly enriched, those significantly depleted, and those neither enriched nor depleted in the ALDH^br population. Yellow bars indicate bulk populations of cardiac-derived cells, green bars indicate ALDH^br cells, and blue bars indicate ALDH^very-br cells. Numbers are enrichment/depletion factors for the indicated surface markers in the ALDH^br population (^∗∗∗𝑃<0.001, ^∗𝑃<0.05 versus ALDH^dim cells).
