适当的器官动态平衡需要严格控制成体干细胞,并通过整合多种输入进行分化。在小鼠的小肠中,Notch和Wnt信号对于干细胞的维持以及分泌和吸收细胞系之间的分化的适当平衡都是必需的。在没有Notch信号的情况下,干细胞优先产生分泌细胞,而不是吸收细胞。在这里,我们使用针对Notch受体的功能阻断抗体来证明Notch阻断通过降低Wnt信号通路的抑制,导致前分泌基因的错误表达来扰乱肠道干细胞的功能。重要的是,Wnt通路的减弱挽救了与Notch阻断相关的表型。这些研究揭示了维持干细胞活性和平衡分化的负调控机制,我们认为这里描述的Wnt和Notch信号之间的相互作用代表了成人干细胞生物学中的一个共同主题。
Proper organ homeostasis requires tight control of adult stem cells and differentiation through integration of multiple inputs. In the mouse small intestine, Notch and Wnt signaling are required both for stem cell maintenance and for a proper balance of differentiation between secretory and absorptive cell lineages. In the absence of Notch signaling, stem cells preferentially generate secretory cells at the expense of absorptive cells. Here, we use function-blocking antibodies against Notch receptors to demonstrate that Notch blockade perturbs intestinal stem cell function by causing a de-repression of the Wnt signaling pathway, leading to mis-expression of prosecretory genes. Importantly, attenuation of the Wnt pathway rescued the phenotype associated with Notch blockade. These studies bring to light a negative regulatory mechanism that maintains stem cell activity and balanced differentiation, and we propose that the interaction between Wnt and Notch signaling described here represents a common theme in adult stem cell biology.
