[Abstract]  

Long-term consequences of stroke significantly impair the quality of life in a growing population of stroke survivors. Hippocampal adult neurogenesis has been hypothesized to play a role in the pathophysiology of cognitive and neuropsychiatric long-term sequelae of stroke. Reliable animal models of stroke are paramount to understanding their biomechanisms and to advancing therapeutic strategies. We present a detailed protocol of a transient cerebral ischemia model which does not cause direct ischemic damage in the hippocampus, allowing investigations into the pathophysiology of long-term

[摘要]  [摘要]中风的长期后果严重损害了越来越多的中风幸存者的生活质量。假定海马成年神经发生在中风的认知和神经精神病学长期后遗症的病理生理学中起作用。可靠的中风动物模型对于理解其生物机制和推进治疗策略至关重要。我们提出 暂时性脑缺血模型的详细协议,该模型不会在海马体中引起直接缺血损伤,从而可以研究中风的长期神经认知缺陷的病理生理学。此外,我们描述了一种用于获取成人海马颗粒细胞的电生理学和形态学特征的急性海马切片的协议。还讨论了与从小细胞(例如未成熟的成年颗粒细胞)进行电生理记录有关的特殊性。本协议可以通过多模式研究(行为,形态结构,生化)加以补充,以期有希望促进研究和中风的长期后遗症的发展以及发现新的治疗机会。

[背景]中风是在发达国家发病率和死亡率的重要原因引起急性和延迟赤字。虽然针对缺血性中风恢复血流的干预策略在降低急性发病率和死亡率方面已经变得更加有效,但中风的长期后果(如中风后抑郁和中风后认知功能障碍和痴呆症)目前正在逃避临床治疗(Wang等。,2010; Loubinoux等人,2012; Mijajlovic ...

In vitro Migration Assays for Neural Stem Cells, Intermediate Neurogenic Progenitors and Immature Neurons

[Abstract]  In the vertebrate central nervous system (CNS), different neural precursor populations such as neural stem cells (NSCs), intermediate neurogenic progenitors (INPs) and immature neurons have to migrate from their places of birth to their location of function. Coordinated migration is mediated by direct cell-cell interactions and by extracellular matrix components, chemoattractants as well as repellents. The migration potential of such populations as well as the responsiveness to chemoattractive compounds can be addressed in isolated cells using in vitro migration assays. Here we ... [摘要]  在脊椎动物中枢神经系统(CNS)中,不同的神经前体细胞如神经干细胞(NSCs),中间神经源性祖细胞(INPs)和不成熟的神经元必须从他们的出生地迁移到它们的功能位置。配位迁移通过直接的细胞 - 细胞相互作用和细胞外基质组分,化学引诱物以及驱避剂介导。这些群体的迁移潜力以及对化学吸引化合物的反应性可以使用体外迁移测定在分离的细胞中解决。在这里我们描述两个迁移测定,基质胶迁移测定和博伊登室迁移测定,其允许在确定的条件下的神经迁移的体外评估(Ladewig,Koch和Brüstle,2014)。基质胶基质是可溶性基底膜提取物。基质胶基质的主要成分是胶原,层粘连蛋白和蛋白聚糖,它们为迁移细胞提供了底物。在基质胶试验中,可以使用相差显微镜分析迁移。 Boyden室测定法(Richards和McCullough,1984)基于微化学趋化室,其由通过具有限定孔径的膜分开的两个室组成。细胞可以接种在上室中并允许通过孔迁移到下室,其中加载了潜在的趋化剂。可以在固定和免疫组织化学染色后分析细胞迁移。原则上,所描述的方案应该适用于其它细胞群体,例如内皮细胞或癌细胞,使用适合于特定细胞类型的个体需要的条件。
