Measurement of Mesenchymal Stem Cells Attachment to Endothelial Cells

[Abstract]  Mesenchymal stem cells (MSCs) have shown profound therapeutic potential in tissue repair and regeneration. However, recent studies indicate that MSCs are largely entrapped in lungs after intravenous delivery and die shortly. The underlying mechanisms have been poorly understood. We have provided evidence to show that excess expression and activation of integrins in culture-expanded MSCs is a critical cause of MSCs adhesion to endothelial cells of the lung microarteries resulting in the entrapment of the cells (Wang et al., 2015). Therefore, it may be meaningful to test the adhesive ability of MSCs to endothelial cells in vitro before intravenous administration to avoid their lung vascular obstructions. Here we report a simple method to measure MSCs attachment to ... [摘要]  间充质干细胞(MSCs)在组织修复和再生中显示出深远的治疗潜力。 然而,最近的研究表明,MSCs在静脉内递送后很大程度上被截留在肺中并且很快死亡。 基本的机制一直不甚了解。 我们提供的证据表明培养扩增的MSCs中整联蛋白的过量表达和活化是MSCs与肺微动脉的内皮细胞粘附的关键原因,导致细胞的包埋(Wang等人 >,2015)。 因此,在静脉给药之前测试MSC对体外内皮细胞的粘附能力以避免它们的肺血管阻塞可能是有意义的。 在这里,我们报告了一种简单的方法来衡量MSC与内皮细胞的附着。

【背景】间充质干细胞(MSCs)正在成为一种极具潜力的治疗药物,许多临床试验正在进行中(Salem和Thiemermann,2010)。由于MSC的方便性和安全性,静脉输注MSCs已成为近期临床试验中MSCs治疗的流行途径(Wu and Zhao,2012)。然而,越来越多的证据表明,MSCs在血管内注射后引起相当大的血管阻塞。在静脉内输注时,超过80%的MSC被包埋在肺中,并且在急性缺血性心脏或脑中仅检测到少于1%的MSC(Lee等人,2009; Toma等人,等人,2009年)。

最近的研究表明,MSCs在静脉内给药后大部分停留在前毛细血管微血管中,并且其中大部分在短期内局部缺血死亡(Toma等人,2009)。因此,血管内给药的MSC的安全性和有效性已成为人们日益关注的问题。尚未完全了解MSCs血管阻塞的机制。 ...

Cyst Detection in Toxoplasma gondii Infected Mice and Rats Brain

[Abstract]  Toxoplasmosis caused by the intracellular parasite Toxoplasma gondii, is characterized by a life-long chronic infection. The parasite is an efficient neurotropic infectious agent that establishes its “safe” life by forming intracellular cysts in chronically infected animals and humans. This protocol describes the specific recipes and method to stain brain cysts from infected mice and rats for further quantification using epifluorescence microscopy. This method provides the possibility to scan the entire brain and thus to numerate all cysts. [摘要]  由胞内寄生虫弓形虫引起的弓形虫病的特征在于终生的慢性感染。 寄生虫是一种有效的亲神经感染剂,通过在慢性感染的动物和人中形成细胞内囊肿来建立其"安全"的生命。 该协议描述了从感染的小鼠和大鼠染色脑囊肿的具体配方和方法,以进一步使用落射荧光显微镜定量。 这种方法提供扫描整个大脑,从而计算所有囊肿的可能性。
