Effects of hUC-MSC-CM on proliferation, cell cycle, and apoptosis of UVB-irradiated HaCaT cells. a Cell morphology, viewed as 10 × 10 cell microscope images. b Cell proliferation. The X-axis represents the cell culture time, the vertical axis represents the total number of cells, and different groups are represented by different line segments. Statistical results are expressed as mean ± standard deviation (n = 3). c, d Changes in cell apoptosis. e, f Changes in the cell cycle. **, p < 0.01; *, p < 0.05; n = 3
