Figure 2

Effects of DA-5512 on Ki-67 levels in human dermal papilla cells. (a) The number of proliferating (Ki-67-positive, red) cells versus total hDPCs was determined. Nuclei were stained with DAPI (blue). Scale bar = 100 μm. (b) Ki-67-positive cells were counted in four nonoverlapping fields in each group and normalized to the total number of hDPCs (DAPI-positive). The concentrations of MXD and DA-5512 were 1 μM and 100 ppm, respectively. All values are expressed as the mean ± SD. versus control.
