Delta‐like homologue 1 (DLK1) promotes the proliferation of hDPSCs. A: shows the EdU labelling in hDPSC/dlk1‐oe and hDPSC/control group (red: EdU labelling; blue: DAPI; 200×). B: shows the quantified results of EdU analyses (by measuring the positive cells); there were much more EdU‐positive cells in hDPSC/dlk1‐oe group than hDPSC/control groups (P<.0001). C: CCK‐8 assay indicated that the cell viability of hDPSC/dlk1‐oe groups was much higher than the hDPSC/control groups (P<.05) on days 1, 3, 5 and 7, and the data represent the mean ± SD of three independent experiments
