2024 Abstract: It remains unknown whether and how intestinal stem cells (ISCs) adapt to inflammatory exposure and whether the adaptation leaves scars that will affect their subsequent regeneration. We investigated the consequences of inflammation on Lgr5+ ISCs in well-defined clinically relevant models of acute gastrointestinal graft-versus-host disease (GI GVHD).

as well as organoid, and in vivo models,揭示了炎症对Lgr5+ ISC的影响, we found that Lgr5+ ISCs undergo metabolic changes that lead to the accumulation of succinate, 本期文章:《细胞—干细胞》:Online/在线发表 美国贝勒医学院Pavan Reddy团队发现,炎症诱导的表观遗传印记调控肠道干细胞, which reprograms their epigenome. These changes reduced the ability of ISCs to differentiate and regenerate ex vivo in serial organoid cultures and also in vivo following serial transplantation. Furthermore,隶属于细胞出版社。
