MSCs from UCB and PL increase CFC expansion of the population enriched in CD34+CD38−Lin− cells. (a) Photographs of colonies obtained on day 14 of culture: (A) CFC-monocytes, (B) CFC-granulocytes, (C) BFC-erythroids, and (D) CFC-erythroids (magnification: 20x). (b) Fold increases in the number of (A) CFC-myeloids and (B) BFC-erythroids and CFC-erythroids in cocultures in the absence and presence of cytokines. Data are shown as the fold increases in total CFC number (BM-MSCs: n = 6; UCB-MSCs: n = 6; and PL-MSCs n = 6). ∗ indicates a statistically significant difference, p < 0.05.
