Isolation, Culture and Differentiation of Adult Hippocampal Precursor Cells

[Abstract]  There are two neurogenic niches in the adult mammalian brain: the subventricular zone of the lateral ventricle and the subgranular zone of the hippocampal dentate gyrus. Cells from these areas can be isolated and maintained in vitro, using two different culture systems to assess their potential regarding proliferation and differentiation in a reductionist model. While the neurosphere assay is primarily performed to directly study the proliferative and differentiation potential of cells in individual brains, the monolayer culture allows single cell analysis in a rather homogeneous cell population. Here, we describe the isolation, culturing methods and differentiation of neural precursor cells in both systems. [摘要]  成年哺乳动物脑中有两个神经生态位:侧脑室下脑室区和海马齿状回颗粒下区。 来自这些区域的细胞可以在体外分离和维持,使用两种不同的培养系统评估它们在还原模型中的增殖和分化的潜力。 虽然神经球测定主要是为了直接研究个体脑中细胞的增殖和分化潜能,单层培养允许在相当均匀的细胞群中进行单细胞分析。 在这里,我们描述了两个系统中的神经前体细胞的分离,培养方法和分化。

【背景】在哺乳动物脑中,成人神经干细胞存在于两个主要神经生态位中,即海马齿状回(DG)的下颗粒区(SGZ)和室下区(SVZ)的侧脑室,其允许新生神经元成人的大脑。来自神经生态位的神经前体细胞可以在体外分离和培养以模拟细胞过程,尤其是增殖和分化。两种标准培养系统,贴壁单层培养(Palmer等人,1995; Ray等人,1995)和神经球测定(Reynolds和Weiss,1992和1996 )在20世纪90年代被引入,代表了在体外研究神经祖细胞生物学的有价值的工具。

根据研究问题,每个系统都有其优点和缺点,在选择其中一种或另一种培养方法之前应该仔细考虑。在贴壁单层培养中,细胞生长相当孤立,形成更均匀的培养物。单层允许直接调查和监测单细胞水平的神经前体细胞。受控条件下的形态,增殖和分化等特征可以很容易地分析和可视化。然而,与神经球培养物相比,以单层培养的细胞代表更复杂的模型,因为细胞通常以更少的通常存在于细胞壁中的细胞 ...

[Abstract]  The necrotrophic white mold fungus Sclerotinia sclerotiorum (S. sclerotiorum) is pathogenic to a broad range of plant species, including the Brassicaceae model plant Arabidopsis thaliana (Boland and Hall, 1994; Bolton et al., 2006). In Arabidopsis thaliana (A. thaliana), the semi-purified proteinaceous S. sclerotinorum elicitor SCFE1 (Sclerotinia culture filtrate elicitor 1) is sensed at the plasma membrane by the receptor-like protein RLP30 and triggers strong immune responses (Zhang et al., 2013), similar to the bacterial elicitor flagellin (Felix et al., 1999). Elicitation of plant defenses with SCFE1 is a tool to dissect the signaling pathway involving RLP30 and to study immunity to necrotrophic ... [摘要]  坏死性白霉菌真菌(Sclerotinia sclerotiorum)(核盘菌)对广泛的植物物种(包括十字花科模式植物拟南芥(Arabidopsis thaliana))具有致病性, (Boland和Hall,1994; Bolton等人,2006)。在拟南芥中(thaliana),是半纯化的蛋白质。通过受体样蛋白RLP30在质膜感测核盘菌诱导物SCFE1(核盘菌属培养物滤液诱发物1),并且引发强烈的免疫应答(Zhang等人。,2013),类似于细菌激发剂鞭毛蛋白(Felix等人,1999)。植物防御与SCFE1的诱导是一个工具,以解剖涉及RLP30的信号通路和研究对坏死性真菌的免疫。在这里,我们描述一个简单的协议来生长。菌核。此外,我们提出了一种两步液相色谱法从培养滤液中部分纯化SCFE1的方法(图1A-B)。通过气相色谱法测定植物应激激素乙烯的发射作为生物测定,以在整个纯化程序中监测级分中的激发剂活性(图1C)。
