ReN-NV administration promotes cell proliferation in hair follicles (HFs). a Immunofluorescence images of Ki67 (green) in HFs from mice receiving depilation and 6-day subcutaneous injection (once per day). Blue indicates nuclei. Scale bar, 50 μm. b The number of Ki67-positive cells in hair matrix was counted. Data are expressed as mean ± SEM. n ≥ 5; **P < 0.01 versus the PBS groups by One-way ANOVA
