    Article Snippet: The sections were stained with hematoxylin and eosin (HE) solution and observed under a Leica Microsystem (Wetzlar, Germany). .. To evaluate the expression of FGF5 and FGF18 in the hair follicles by immunohistochemistry, the sections were incubated in 3% H2O2 for 25 min and then blocked with 3% BSA for 4 h. They were then incubated with anti-FGF5 antibody (1: 500 dilution; Proteintech, Wuhan, China) or anti-FGF18 antibody (1:500 dilution; Proteintech, Wuhan, China) overnight at 4°C. .. After three washes with PBS, the sections were incubated with horseradish peroxidase-conjugated secondary antibodies for 4 h at 37°C and then with 3,3-diaminobenzidine (DAB) for about 3 min. All stained sections were examined with a DM3000 microscope (Leica, Wetzlar, Germany) to determine the histological changes.
