摘　　要：目的 HGF及其受体c-met是很多系统中间充质-上皮互相作用的主要的介导者,毛囊周期性生长是典型的间充质-上皮互作模型,为证实HGF/c-met信号在小鼠毛囊周期生长过程中是否发挥作用。方法本实验运用免疫组织化学的方法对HGF/c-met在ICR小鼠毛囊生长期、退化期和休止期进行组织定位。结果 HGF主要位于真毛乳头和皮脂腺,c-met主要位于毛基质、根鞘部和表皮。HGF及其受体在小鼠毛囊生长期表达量达到最高值,在退化期基本不表达,在休止期-生长期过渡时HGF及其受体表达量均上升。结论 HGF/c-met信号在ICR小鼠毛囊生长过程中起调控作用。Objective HGF and its receptor（ c-met） are principal mediators of mesenchymal-epithelial interaction in several different systems. Moreover,hair follicle is a model of mesenchymal-epithelial interaction. The aim of this study was to explore whether HGF / c-met signal plays a role in the control of hair follicle growth cycle. Methods To examine the localization of HGF / c-met in anagen,catagen and telogen in the hair follicle of ICR mice. Results HGF was mainly located in the dermal papilla and sebaceous gland,and c-Met in the hair matrix,root sheath and epidermis. Both HGF and c-met expressions peaked during anagen,not found in catagen,and increased during telogen-anagen phase. Conclusions Our results demonstrate a regulatory role of HGF and c-met in the control of hair follicle growth in ICR mice.
