Figure 4. Stem/progenitor and stromal markers are highly discordant between S, ID and Ex BM-MSCs.

a-d, Gene specific heatmaps of commonly used phenotypic markers (a), lineage differentiation markers (b), matrix remodeling genes (c), and paracrine acting factors (d) for S, ID, and Ex BM-MSCs. Color scale corresponds to per-gene z-score computed across each row. e, QPCR quantification of select genes from (a-d) in ID and Ex BM-MSCs. Data are mean ± SD and p values are by student‟s t test.
