Sagittal sectional views of histological observation of hair follicles in C57BL/6 mice. A HE staining on dorsal skin taken from the shaved area with 4 × objective lens. Scale bar = 100 μm. B Quantitative analysis on the number of hair follicles. C CD31 immuno-histochemical staining of dermal sections with 10 × objective lens (black arrows indicate CD31—positive micro-vessels). Scale bar = 100 μm. D Quantitative analysis of CD31 staining surrounding hair follicles. E Ki67 immunohistochemically staining of dermal sections with 20 × objective lens. Scale bar = 100 μm. F Quantitative analysis of Ki67 staining inside hair follicles. G Western blot analysis probing for androgen receptor (AR) after CEFFE treatment. Density values were presented in arbitrary units (AU). Original data was presented in Additional file 2: Fig. S3. Data represent the mean ± SD; *P < 0.05
