[Abstract] Vascular smooth muscle cells (VSMCs) have been cultured for decades to study the role of these cells in cardiovascular disorders. The most common source of VSMCs is the rat aorta. Here we show the adaptation of this method to isolate and culture mouse aortic VSMCs. The advantage of this method is that there are many more transgenic mouse lines available compared to rats. The protocol consists of the isolation of the aorta, the liberation of vascular cells by the action of collagenase, culturing of VSCMs, and analyzing filamentous actin and alpha smooth muscle actin by fluorescence microscopy. VSCMs can be further used to study mechanisms underlying cardiovascular diseases.

[摘要] [摘要]血管平滑肌细胞（VSMC）已培养了数十年，以研究这些细胞在心血管疾病中的作用。VSMC的最常见来源是大鼠主动脉。在这里，我们展示了此方法对分离和培养小鼠主动脉VSMC的适应性。这种方法的优点是，与大鼠相比，有更多的转基因小鼠系可用。该方案包括主动脉的分离，通过胶原酶的作用释放血管细胞，培养VSCM ，通过荧光显微镜分析丝状肌动蛋白和α平滑肌肌动蛋白。VSCM可进一步用于研究心血管疾病的潜在机制。

[背景]血管壁细胞（壁细胞）在多种疾病的调节中起着至关重要的作用，从高血压（Rodríguez-Vita等，2005a）和动脉粥样硬化（Rodríguez-Vita等，2008）到癌症（ Wong等人，2020年），甚至最近还有COVID-19 （He等人，2020年）。毛细血管大部分被周细胞覆盖，而较大的血管在血管壁中含有VSCM。壁细胞通过血管收缩和血管舒张来控制血流。这样，吨哎是在几种药物靶，其降低血压（圣保罗等人，2020） ...

[Abstract] Neuroblast migration is a major component in the process of neuronal circuit assembly. In the rodent postnatal brain, the subependymal zone (SEZ) is the largest neurogenic niche where new neurons are born throughout life. These cells migrate several millimeters following a specific pathway called the rostral migratory stream (RMS) towards the olfactory bulb. Once they reach their final destination, they differentiate mainly as interneurons and integrate into already established neuronal circuits. Along the RMS, neuroblasts use a particular mode of migration known as chain migration. They stay attached to each other while migrating and are intimately associated with adjacent astrocytic processes. To dissect the molecular and cellular signals involved in neuroblast migration, we developed ...
[摘要] 神经母细胞迁移是神经元电路组装过程中的主要组成部分。 在啮齿动物出生后的大脑中，子宫颈区（SEZ）是新生神经元生命中最大的神经源性生态位。 这些细胞沿着称为传播流（RMS）的特定途径朝向嗅球迁移几毫米。 一旦达到其最终目的地，它们主要区分为中间神经元并整合到已建立的神经元回路中。 沿着RMS，神经母细胞使用称为链转移的特定迁移模式。 它们在迁移时保持相互依赖，并与相邻的星形细胞过程密切相关。 为了解剖神经母细胞迁移中涉及的分子和细胞信号，我们开发了一种体外系统，其由在星形胶质细胞单层顶部共培养的经SEZ衍生的外植体组成。
