在哺乳动物皮肤中,需要多种类型的驻留细胞来产生功能性组织并支持组织稳态和再生。组成皮肤稳态和再生的上皮干细胞小生境的细胞还没有很好的定义。在这里,我们确定了皮肤内的脂肪前体细胞,并证明它们的动态再生与皮肤干细胞的激活平行。在脂肪形成缺陷的小鼠和移植实验中,脂肪细胞谱系细胞的功能分析显示,皮内脂肪细胞谱系细胞是驱动卵泡干细胞活化所必需的且足够的。此外,我们牵连的PDGF表达的未成熟脂肪细胞在卵泡干细胞活性的调节。这些数据突出了成脂细胞作为正调节皮肤干细胞活性的皮肤小生境细胞,并表明脂肪细胞谱系细胞可能在临床上改变上皮干细胞功能。
In mammalian skin, multiple types of resident cells are required to create a functional tissue and support tissue homeostasis and regeneration. The cells that compose the epithelial stem cell niche for skin homeostasis and regeneration are not well defined. Here, we identify adipose precursor cells within the skin and demonstrate that their dynamic regeneration parallels the activation of skin stem cells. Functional analysis of adipocyte lineage cells in mice with defects in adipogenesis and in transplantation experiments revealed that intradermal adipocyte lineage cells are necessary and sufficient to drive follicular stem cell activation. Furthermore, we implicate PDGF expression by immature adipocyte cells in the regulation of follicular stem cell activity. These data highlight adipogenic cells as skin niche cells that positively regulate skin stem cell activity, and suggest that adipocyte lineage cells may alter epithelial stem cell function clinically.
