[Abstract]  Isolation and tridimensional culture of murine fetal progenitors from the digestive tract represents a new approach to study the nature and the biological characteristics of these epithelial cells that are present before the onset of the cytodifferentiation process during development. In 2013, Mustata et al. described the isolation of intestinal fetal progenitors growing as spheroids in the ex vivo culture system initially implemented by Sato et al. (2009) to grow adult intestinal stem cells. Noteworthy, fetal-derived spheroids have high self-renewal capacity making easy their indefinite maintenance in culture. Here, we report an adapted protocol for isolation and ex vivo culture and maintenance of fetal epithelial progenitors from distal pre-glandular ... [摘要]  来自消化道的鼠胎儿祖细胞的分离和三维培养代表了研究在发育过程中细胞分化过程开始前存在的这些上皮细胞的性质和生物学特征的新方法。在2013年,Mustata等人描述了在最初由佐藤等人实施的离体培养系统中分离作为球体生长的肠胎细胞祖细胞。 >(2009)增长成年肠干细胞。值得注意的是,胎儿衍生的球体具有较高的自我更新能力,使其在文化中的无限期维护变得容易。在这里,我们报告了用于分离和远离前胃腺胃生长为胃球体的胎儿上皮祖细胞的分离和离体培养和维持的修改方案(Fernandez Vallone等人, 2016)。

背景 来自腺体的小鼠成体干细胞可以在3D matrigel中离体生长,作为“迷你腺体”无限期(Barker等人,2010) 。与在EGF,Noggin和R-spondin 1存在下生长的小肠的干细胞相比,成年胃干细胞需要进一步补充Fgf10,胃泌素,Wnt3a和更高浓度的R-spondin 1以获得生产性 - 文化。相比之下,到目前为止,很少知道在发育期间排列前腺上皮细胞的胎儿细胞。到目前为止,它们的性质以及其离体的潜在生长特性未明确。基于以前的研究,确定胎儿小肠(Mustata等人,2013年)中存在的细胞,我们报告了作为球体的小鼠胎儿胃祖细胞的培养(Fernandez Vallone et al。 。,2016)。可以在2009年由佐藤等人先前报道的培养基中重复胃祖细胞以生长小肠成体干细胞,与成人型胃干细胞相反,它们不需要额外的生长因子补充(Fgf10,Wnt3a或胃泌素)。 ...
