The adult hair follicle houses stem cells that govern the cyclical growth and differentiation of multiple cell types that collectively produce a pigmented hair. Recent studies have revealed that hair follicle stem cells are heterogeneous and dynamic throughout the hair cycle. Moreover, interactions between heterologous stem cells, including both epithelial and melanocyte stem cells, within the hair follicle are just now being explored. This review will describe how recent findings have expanded our understanding of the development, organization, and regeneration of hair follicle stem cells. At a basic level, this review is intended to help construct a reference point to integrate the surge of studies on the molecular mechanisms that regulate these cells.
成人毛囊中存在干细胞,这些干细胞调控着多种细胞类型的周期性生长和分化,这些细胞共同产生有色素的毛发。最近的研究揭示了毛囊干细胞在整个毛发生长周期中具有异质性和动态性。此外,毛囊内异质干细胞(包括上皮干细胞和黑素细胞干细胞)之间的相互作用才刚刚开始被探索。这篇综述将描述最近的发现如何扩展了我们对毛囊干细胞的发育、组织和再生的理解。在基础层面上,这篇综述旨在帮助构建一个参考点,以整合调控这些细胞的分子机制的大量研究。
