为了使组织再生和/或修复伤口,干细胞必须从周围环境中接收外部信号,并将其与其内在的自我更新和分化能力整合,以形成组织。越来越多的证据表明,转化生长因子-βs(transforming growth factor-βs,TGF-βs)超家族是干细胞与其微环境之间细胞间串扰的组成部分。本文就TGF-β超家族在胚胎干细胞和成体干细胞中的功能研究进展作一综述。我们讨论这些途径如何帮助定义干细胞所在的生理环境,以及信号通路的扰动如何导致癌症。
To rejuvenate tissues and/or repair wounds, stem cells must receive extrinsic signals from their surrounding environment and integrate them with their intrinsic abilities to self-renew and differentiate to make tissues. Increasing evidence suggests that the superfamily of transforming growth factor-βs (TGF-βs) constitute integral components in the intercellular crosstalk between stem cells and their microenvironment. In this review, we summarize recent advances in our understanding of TGF-β superfamily functions in embryonic and adult stem cells. We discuss how these pathways help to define the physiological environment where stem cells reside, and how perturbations in the signaling circuitry contribute to cancers.
