干细胞存在于调节其自我更新和分化的专门小生境中。血管系统正在成为干细胞龛的重要组成部分。在这里,我们表明,成人脑室下区(SVZ)神经干细胞龛包含一个广泛的平面血管丛,具有专门的属性。分裂的干细胞和它们的转运扩增后代在稳态和再生期间都与SVZ血管紧密贴壁。它们经常在缺乏星形胶质细胞终足和周细胞覆盖的部位接触血管系统,这是SVZ特有的血脑屏障的修饰。此外,再生经常发生在这些网站。最后,我们发现血液中的循环小分子进入SVZ。因此,血管系统是成人SVZ神经干细胞生态位的关键组成部分,SVZ干细胞和转运放大细胞独特地准备接收来自血管系统的不同元件的空间线索和调节信号。
Stem cells reside in specialized niches that regulate their self-renewal and differentiation. The vasculature is emerging as an important component of stem cell niches. Here, we show that the adult sub-ventricular zone (SVZ) neural stem cell niche contains an extensive planar vascular plexus that has specialized properties. Dividing stem cells and their transit-amplifying progeny are tightly apposed to SVZ blood vessels both during homeostasis and regeneration. They frequently contact the vasculature at sites that lack astrocyte endfeet and pericyte coverage, a modification of the blood-brain barrier unique to the SVZ. Moreover, regeneration often occurs at these sites. Finally, we find that circulating small molecules in the blood enter the SVZ. Thus, the vasculature is a key component of the adult SVZ neural stem cell niche, with SVZ stem cells and transit-amplifying cells uniquely poised to receive spatial cues and regulatory signals from diverse elements of the vascular system.
