成体组织特异性干细胞对于维持组织稳态至关重要,也是损伤修复或疾病期间再生的关键。许多关键的干细胞功能依赖于来自微环境或生态位的适时线索的存在,其中包括多种成分,包括神经元、循环和细胞外基质输入以及一系列与干细胞直接相互作用的邻近生态位细胞。然而,由于成体干细胞功能、其内在控制和多种调节生态位成分的复杂性,干细胞及其生态位的研究一直具有挑战性。在这里,我们回顾了最近在理解干细胞及其生态位之间的复杂相互作用方面取得的重大进展,这些进展是通过单细胞转录组分析、干细胞生态位的 3D 体外培养和 4D 体内显微镜技术的巨大技术飞跃而实现的。
Adult tissue-specific stem cells are essential for homeostatic tissue maintenance and key to regeneration during injury repair or disease. Many critical stem cell functions rely on the presence of well-timed cues from the microenvironment or niche, which includes a diverse range of components, including neuronal, circulating and extracellular matrix inputs as well as an array of neighboring niche cells directly interacting with the stem cells. However, studies of stem cells and their niche have been challenging due to the complexity of adult stem cell functions, their intrinsic controls and the multiple regulatory niche components. Here, we review recent major advances in our understanding of the complex interplay between stem cells and their niche that were enabled by the tremendous technological leaps in single-cell transcriptome analyses, 3D in-vitro cultures and 4D in-vivo microscopy of stem cell niches.
