Immunohistochemical Identification of Human Skeletal Muscle Macrophages

[Abstract]  Macrophages have well-characterized roles in skeletal muscle repair and regeneration. Relatively little is known regarding the role of resident macrophages in skeletal muscle homeostasis, extracellular matrix remodeling, growth, metabolism and adaptation to various stimuli including exercise and training. Despite speculation into macrophage contributions during these processes, studies characterizing macrophages in non-injured muscle are limited and methods used to identify macrophages vary. A standardized method for the identification of human resident skeletal muscle macrophages will aide in the characterization of these immune cells and allow for the comparison of results across studies. Here, we present an immunohistochemistry (IHC) protocol, validated by flow cytometry, to distinctly ... [摘要]  巨噬细胞在骨骼肌修复和再生中具有很好的特征。关于驻留巨噬细胞在骨骼肌动态平衡,细胞外基质重塑,生长,代谢和适应各种刺激(包括运动和训练)中的作用知之甚少。尽管在这些过程中推测了巨噬细胞的贡献,但表征非受伤肌肉中的巨噬细胞的研究是有限的,用于鉴定巨噬细胞的方法各不相同。用于鉴定人类骨骼肌巨噬细胞的标准化方法将有助于鉴定这些免疫细胞,并可用于各研究结果的比较。在这里,我们提出免疫组织化学(IHC)协议,通过流式细胞术验证,以清楚地识别常驻人类骨骼肌巨噬细胞种群。我们显示CD11b和CD206双IHC有效识别人骨骼肌中的巨噬细胞。此外,非受伤人骨骼肌中的大多数巨噬细胞表现出“混合”M1 / M2表型,表达CD11b,CD14,CD68,CD86和CD206。在休息的骨骼肌中存在相对较少的CD11b + / CD206-巨噬细胞群。这种人口的相对丰度的变化可能反映了骨骼肌肉环境的重要变化。肌肉中的CD11b和CD206 IHC也显示出巨噬细胞的不同形态学特征,这些特征可能与这些细胞的功能状态有关。

【背景】巨噬细胞是能够适应局部微环境变化的多向性免疫细胞。在过去几年中,研究表明巨噬细胞表型是动态的,存在于连续统一体中(Mosser and Edwards,2008,Italiani and Boraschi,2014,Martinez and ...

Sebinger Culture: A System Optimized for Morphological Maturation and Imaging of Cultured Mouse Metanephric Primordia

[Abstract]  Here, we present a detailed protocol on setting up embryonic renal organ cultures using a culture method that we have optimised for anatomical maturation and imaging. Our culture method places kidney rudiments on glass in a thin film of medium, which results in very flat cultures with all tubules in the same image plane. For reasons not yet understood, this technique results in improved renal maturation compared to traditional techniques. Typically, this protocol will result in an organ formed with distinct cortical and medullary regions as well as elongated, correctly positioned loops of Henle. This article describes our method and provides detailed advice. We have published qualitative and quantitative evaluations on the performance of the technique in Sebinger et al. (2010) ... [摘要]  在这里,我们提出了一个详细的协议,建立胚胎肾脏器官培养使用培养方法,我们已经优化解剖成熟和成像。 我们的培养方法是将肾脏的基质放在玻璃上,形成一层薄薄的培养基,培养的平面非常平坦,所有的肾小管都在同一图像平面上。 由于尚未理解的原因,与传统技术相比,该技术导致肾成熟的改善。 通常情况下,这个协议将导致器官形成不同的皮层和髓质区域,以及拉长,正确定位的亨利循环。 本文介绍了我们的方法并提供了详细的建议。 我们已经在Sebinger等人(2010)和Chang和Davies(2012)上发表了关于该技术性能的定性和定量评估。

【背景】哺乳动物的后肾(永久性)肾发育于位于中胚层尾端的简单遗传。在小鼠胚胎日('E')10,这些基因形成并由两种形态上可区分的组分组成;产生为Wolffian(肾)导管的憩室的上皮性输尿管芽,以及形成在导管旁的后肾间质(metanephrogenic mesenchyme)。随着发育进展,输尿管芽进入后肾间质,经历多轮生长和分枝,形成“树”。这后来重塑以产生一个成熟的集合管系统,其中肾小管从中心腔,肾盂放射(Lindstrom等人,2015)。肾盂排水到输尿管,从输尿管芽的原始茎形成。随着输尿管芽发育,它诱导来自后肾间充质细胞的细胞在其每个尖端周围凝结形成“帽间充质”(Schreiner,1902; ...
