脊椎动物造血干细胞(HSC)从“造血”内皮细胞出现在主动脉-性腺-中肾(AGM)区域。在这里,我们发现促炎细胞因子 Ifn-γ 及其受体 Crfb17 正向调节斑马鱼 HSC 的发育。这种调节似乎并不调节 HSC 或内皮细胞的增殖或存活,而是调节内皮细胞向 HSC 的转变。 Notch 信号和血流正向调节 AGM 中 ifng 和 crfb17 的表达。值得注意的是,Ifn-γ 过表达部分挽救了在缺乏血流或 Notch 信号传导的情况下观察到的 HSC 损失。重要的是,Ifn-γ 信号传导通过细胞自主作用来控制内皮细胞向 HSC 的转变。 Ifn-γ 在 AGM 中激活 Stat3(一种 Ifn-γ 信号传导的非典型转导器),而 Stat3 抑制会减少 HSC 形成。总之,我们的研究结果揭示了炎症细胞因子的发育作用,并将其作用置于 Notch 信号传导和血流下游,以控制 Stat3 激活和 HSC 出现。
Vertebrate hematopoietic stem cells (HSCs) emerge in the aorta-gonad-mesonephros (AGM) region from “hemogenic” endothelium. Here we show that the pro-inflammatory cytokine Ifn-γ and its receptor Crfb17 positively regulate HSC development in zebrafish. This regulation does not appear to modulate the proliferation or survival of HSCs or endothelial cells, but rather the endothelial to HSC transition. Notch signaling and blood flow positively regulate the expression of ifng and crfb17 in the AGM. Notably, Ifn-γ overexpression partially rescues the HSC loss observed in the absence of blood flow or Notch signaling. Importantly, Ifn-γ signaling acts cell-autonomously to control the endothelial to HSC transition. Ifn-γ activates Stat3, an atypical transducer of Ifn-γ signaling, in the AGM, and Stat3 inhibition decreases HSC formation. Together, our findings uncover a developmental role for an inflammatory cytokine and place its action downstream of Notch signaling and blood flow to control Stat3 activation and HSC emergence.
