成体干细胞对于组织稳态和伤口修复是必不可少的。它们的增殖能力必须受到严格调控,以防止出现不需要的和潜在危险的细胞,如癌细胞。我们发现,缺乏促凋亡Sept 4/ARTS基因的小鼠,毛囊干细胞(HFSC)的数量增加,这些细胞受到保护,不受凋亡的影响。Sept 4/ARTS−/−小鼠在伤口愈合和毛囊再生方面表现出显着改善。这些表型依赖于HFSC,如谱系追踪所示。XIAP是ARTS的直接靶点,其失活可消除这些表型并损害伤口愈合。我们的研究结果表明,细胞凋亡在调节干细胞依赖性再生中起着重要作用,并表明该途径可能是再生医学的目标。
Adult stem cells are essential for tissue homeostasis and wound repair. Their proliferative capacity must be tightly regulated to prevent the emergence of unwanted and potentially dangerous cells, such as cancer cells. We found that mice deficient for the proapoptotic Sept4/ARTS gene have elevated numbers of hair follicle stem cells (HFSCs) that are protected against apoptosis. Sept4/ARTS−/− mice display marked improvement in wound healing and regeneration of hair follicles. These phenotypes depend on HFSCs, as indicated by lineage tracing. Inactivation of XIAP, a direct target of ARTS, abrogated these phenotypes and impaired wound healing. Our results indicate that apoptosis plays an important role in regulating stem cell–dependent regeneration and suggest that this pathway may be a target for regenerative medicine.
