研究调控内皮细胞生长和存活的机制对于理解内皮细胞的动态平衡和内皮细胞如何维持干细胞生态位具有重要意义。我们在这里报道,成人内皮细胞中ID基因的靶向性丢失会导致血窦扩张、渗漏和促炎状态,随着时间的推移,这种状态的严重性会增加。肝窦完整性的破坏会导致造血干细胞(HSC)的增殖、分化、迁移和衰竭。机制上,由于ID基因消融后Bcl2家族基因表达减少,窦状内皮细胞(SECs)显示出更多的细胞凋亡。此外,Id1−/−Id3−/−Secs和上游H型血管表现出细胞周期蛋白依赖性激酶抑制因子p21和p27的表达增加,增殖能力减弱,这可以通过减少E2-2的表达来挽救。Id1−/−Id3−/−小鼠由于血管再生受损和造血功能衰竭,无法在亚致死剂量照射下存活。因此,ID基因是BM Secs在体内平衡和应激期间生存和再生所必需的,以维持HSC的发育。
Investigating mechanisms that regulate endothelial cell (EC) growth and survival is important for understanding EC homeostasis and how ECs maintain stem cell niches. We report here that targeted loss of Id genes in adult ECs results in dilated, leaky sinusoids and a pro-inflammatory state that increases in severity over time. Disruption in sinusoidal integrity leads to increased hematopoietic stem cell (HSC) proliferation, differentiation, migration, and exhaustion. Mechanistically, sinusoidal ECs (SECs) show increased apoptosis because of reduced Bcl2-family gene expression following Id gene ablation. Furthermore, Id1−/−Id3−/− SECs and upstream type H vessels show increased expression of cyclin-dependent kinase inhibitors p21 and p27 and impaired ability to proliferate, which is rescued by reducing E2-2 expression. Id1−/−Id3−/− mice do not survive sublethal irradiation because of impaired vessel regeneration and hematopoietic failure. Thus, Id genes are required for the survival and regeneration of BM SECs during homeostasis and stress to maintain HSC development.
