Tissue-resident immune cells with potent sensing and effector functions are well-placed to fundamentally aid tissue homeostasis via crosstalk with stem cells. In this issue of Cell Stem Cell, Wang et al. (2019) identify a dermis-resident TREM2+ macrophage subpopulation that promotes hair follicle stem cell quiescence via cytokine-mediated JAK-STAT signaling.
组织驻留免疫细胞具有强大的感应和效应功能,通过与干细胞的相互作用,非常适合从根本上帮助组织稳态。在本期《Cell Stem Cell》杂志上,Wang 等人(2019 年)鉴定出一种真皮驻留的 TREM2+巨噬细胞亚群,该亚群通过细胞因子介导的 JAK-STAT 信号通路促进毛囊干细胞静止。
