[Abstract] This protocol aims to study intercellular transport of mitochondria, dynamic cellular organelles via tunnelling nanotubes (TNT), a cell membrane extension of cytoskeletal elements. The nanotubular bridges or the tunnelling nanotube highways are one of the emerging new cell-to-cell communication systems which mediates exchange of cellular materials, most importantly as in our observation, mitochondria. Mesenchymal stem cells (MSC) have been well studied to be endowed with a highly efficient intercellular mitochondrial donation ability and this property is now proven crucial to its functional ...
[摘要] 此协议旨在研究线粒体，动态细胞器通过隧道纳米管（TNT），细胞骨架元素的细胞膜扩展的细胞间运输。 纳米管桥或隧道纳米管高速公路是新兴的新的细胞到细胞通信系统之一，其介导细胞材料的交换，最重要的是在我们的观察中，线粒体。 间充质干细胞（MSC）已经被充分研究以赋予高效的细胞间线粒体捐赠能力，并且这种性质现在被证明对于其在细胞治疗中的挽救的功能作用是至关重要的。

[Abstract] To characterize macrophage gene expression profiles during the uptake of autologous apoptotic cells, we developed a unique, more physiologic system using primary human monocyte derived macrophages purified via a nonactivating isolation procedure (and in the absence of contaminating platelets, which can release stimulating signals if activated) and autologous lymphocytes as a source of apoptotic cells. The use of autologous cells as the apoptotic target rather than transformed cell lines avoids antigenic stimulation from “nonself” structures at the HLA level but also from “altered self” ...
[摘要] 为了表征在自体凋亡细胞摄取期间的巨噬细胞基因表达谱，我们开发了一种独特的，更生理的系统，使用通过非活化分离程序纯化的原代人单核细胞衍生的巨噬细胞（和在没有污染的血小板，如果激活可以释放刺激信号 ）和自体淋巴细胞作为凋亡细胞的来源。 使用自体细胞作为凋亡靶而不是转化细胞系避免了来自HLA水平上的"非自身"结构的抗原刺激，而且还由于细胞系中固有的转化而导致的"改变的自身"信号。
