Isolation, Purification and Characterization of Exosomes from Fibroblast Cultures of Skeletal Muscle

[Abstract]  Exosomes are dynamic nanovesicles secreted by virtually all cells and are present in all biological fluids. Given their highly heterogeneous content exosomes have been implicated in many physiological and pathological processes that they exert by influencing cell-cell and cell-ECM communication. In recent years an increasing number of methods have been established for the purification and characterization of exosomes. These include ultracentrifugation, ultrafiltration, size exclusion chromatography, immune capture and precipitation using a proprietary polymer. Here, we provide a protocol based on differential ultracentrifugation and sucrose density gradients tailored for the isolation of crude and ultra-pure exosomes from primary fibroblast cultures derived from adult mouse skeletal ... [摘要]  [摘要 ] 外来体是几乎所有细胞分泌的动态纳米囊泡,并存在于所有生物体液中。鉴于它们的异质含量很高,外泌体已牵涉到它们通过影响细胞-细胞和细胞-ECM通讯而发挥的许多生理和病理过程。近年来,已经建立了越来越多的方法外泌体的纯化和表征。其中包括超速离心,超滤,尺寸排阻色谱,免疫捕获和使用专有聚合物的沉淀。在这里,我们提供了基于差分超速离心和蔗糖密度梯度的协议,该协议专门用于从成年小鼠骨骼肌衍生的原代成纤维细胞培养物中分离粗制和超纯外泌体。可以对该协议进行修改和修改,以从各种组织和体液中分离和表征外泌体。


背景 ] ë xosomes是单膜,异质纳米囊泡直径范围从30至150nm,secre 由所有细胞和存在于几乎所有的体液泰德。外泌体中存在的可溶性和膜大分子,mRNA,microRNA的光谱取决于代谢状态以及分泌这些纳米囊泡的细胞的发育起源。由于它们的货物组成,外泌体可以启动接收细胞中的信号传导途径,并参与了发育,免疫和正常组织生理的维持。在神经退行性疾病,纤维化和癌症等疾病条件下,它们被证明可以触发和传播病理刺激(Rackov 等,2018; Gurunathan 等,2019; van de Vlekkert 等,2019)。在这里,我们描述了从成年小鼠腓肠肌(GA)肌肉建立的成纤维细胞培养物中纯化外泌体的方案(van de Vlekkert ...

[Abstract]  Dinoflagellates are unicellular algae that can have photosynthetic or nonphotosynthetic lifestyles. Dinoflagellates in the genus Symbiodinium can enter endosymbiotic associations with corals, providing the metabolic basis for the highly productive and biologically diverse coral-reef ecosystems (Hoegh-Guldberg, 1999), as well as with other cnidarians, including sea anemones and jellyfish, and non-cnidarian hosts (Trench, 1993; Lobban et al., 2002; Mordret et al., 2016).

Here, I describe a protocol for isolating total RNA from Symbiodinium cells.
[摘要]  鞭毛藻是单细胞藻类,可以有光合或非光合生活方式。 Symbiodinium属中的甲藻类可以与珊瑚进入内共生关系,为高生产力和生物多样性珊瑚礁生态系统提供代谢基础(Hoegh-Guldberg,1999),以及其他的cnidarians,包括 海葵和海蜇,以及非刺猬寄主(Trench,1993; Lobban等人,2002; Mordret等人,2016)。

在这里,我描述了从Symbiodinium细胞中分离总RNA的方案。

Magnetic Resonance Imaging and Histopathological Visualization of Human Dural Lymphatic Vessels

[Abstract]  In this protocol, we describe a method to visualize and map dural lymphatic vessels in-vivo using magnetic resonance imaging (MRI) and ex-vivo using histopathological techniques. While MRI protocols for routine imaging of meningeal lymphatics include contrast-enhanced T2-FLAIR and T1-weighted black-blood imaging, a more specific 3D mapping of the lymphatic system can be obtained by administering two distinct gadolinium-based MRI contrast agents on different days (gadofosveset and gadobutrol) and subsequently processing images acquired before and after administration of each type of contrast. In addition, we introduce methods for optimal immunostaining of lymphatic and blood vessel markers in human dura mater ex-vivo. [摘要]  在该协议中,我们描述了一种使用组织病理学技术使用磁共振成像(MRI)和体外可视化和绘制硬膜淋巴管体内的方法。 虽然用于脑膜淋巴管的常规成像的MRI方案包括对比增强的T2-FLAIR和T1加权的黑血成像,但是可以通过在不同日期施用两种不同的基于钆的MRI造影剂来获得更具体的淋巴系统3D图谱 (gadofosveset和钆布醇)并且随后处理在施用每种类型的对比之前和之后采集的图像。 此外,我们介绍了在人体硬脑膜内进行淋巴和血管标志物最佳免疫染色的方法。

【背景】在大脑免疫特权的原因是没有实质淋巴管。 然而,最近的研究发现了啮齿动物硬脑膜中广泛的淋巴循环系统(Aspelund等人,2015; Louveau等人,2015),提供了可能的途径 用于消除大脑的废物和免疫细胞进入深部颈部淋巴结。 在这个协议中,我们描述了一种方法来:(1)使用MRI的头部显示硬脑膜内的淋巴管体内,和(2)使用优化评估淋巴管的局部存在 免疫染色方法(Absinta等人,2017)。 淋巴管的体内成像可以更详细地研究废物清除和免疫功能的机制及其在各种疾病和衰老中的潜在异常。
