Abstract:
Objective Hair follicle stem cells (HFSCs) can be cultured in vti ro to differentiate into chondrocytes, osteoblasts and adipocytes .The aim of the article was to investigate the culture method of HFSCs and their adipogenic and osteogenic differentiation potentials. Methods Microdissection and two-step enzyme digestion were applied to obtain HFSCs , and HFSCs are purified by differ-ential adhesion method.The cells were cultured in keratinocyte serum-free medium obtaining 10% fetal bovine serum.Flow cytometry was used to detect CD34、β1-integrin and CK15.The third-generation HFSCs were cultured by osteogenic inductor and adipogenic induc-tor respectively . Results Cultured HFSCs were homogeneous in shape , bearing the property of great refraction and typical cobble-stone-morph.By flow cytometry, the expression rates of CD34,β1-integrin and CK15 were 59.6%, 97.0%and 61.1%.Stem cells were in good growing condition from the third-generation cell growth curve.21 days after being induced by osteogenic inductor, calcified nodules appeared after alizarin red staining, while 14 days after being induced by adipogenic inductor, intracellular lipid droplets could be observed after oil red O staining. Conclusion Cultured HFSCs are chaterized by strong growth capacity and multiple differentiation potential .
