[Abstract]  In myocardial infarction (MI), a plenty of cardiomyocytes undergo necrosis and necroptosis due to the lack of oxygen and nutrients. The dead cardiomyocytes are promptly engulfed by phagocytes. When the dead cells are not engulfed, the noxious contents of the cells are released outside, and thus, induce inflammation, and obstruct the function of organs. Therefore, phagocytosis is crucial for maintaining homeostasis of organs. Herein, we describe a protocol of an in vitro phagocytosis assay of necroptotic cells. [摘要]  在心肌梗死(MI)中,由于缺氧和营养,大量心肌细胞发生坏死和坏死。 死亡心肌细胞迅速吞噬吞噬细胞。 当死细胞不被吞没时,细胞的有害物质被释放到外部,从而引起炎症,并阻碍器官的功能。 因此,吞噬对维持器官的体内平衡至关重要。 在这里,我们描述了一种神经细胞的体外吞噬作用测定方案。
【背景】以前,认为坏死性坏死细胞和坏死核细胞只能通过心脏巨噬细胞在失败的心脏中消除。 然而,我们发现负责组织纤维化的心脏肌成纤维细胞在MI后吞噬死细胞(Nakaya等,2017)。 本文中,我们提供了一种细胞凋亡细胞的体外吞噬作用的详细方案,采用在caspase-3抑制剂Z-VAD-FMK中通过TNF-α刺激进行人脑坏死的L929细胞。

[Abstract]  Mesenchymal stem cells (MSCs), first described in human bone marrow, are emerging as promising cell-based therapeutics for a wide range of diseases (Caplan and Correa, 2011). MSCs have been isolated from various organs in the body, and synovial MSCs were first reported by De Bari et al. (2001). We previously reported that synovial MSCs have superior proliferation and chondrogenic potentials as compared to bone marrow-, muscle-, and adipose- derived MSCs in humans (Sakaguchi et al., 2005) and rats (Yoshimura et al., 2007). In addition, administration of synovial MSCs for osteochondral defect promoted cartilage regeneration in a rabbit (Koga et al., 2008) and a pig model (Nakamura et al., 2012). In 2008, we started a clinical trial in human and ... [摘要]  首先在人骨髓中描述的间充质干细胞(MSC)正在作为用于广泛疾病的有希望的基于细胞的治疗剂出现(Caplan和Correa,2011)。 MSC已经从体内各种器官中分离,并且滑膜MSCs首先由De Bari等人(2001)报道。我们先前报道了与人类骨髓,肌肉和脂肪来源的MSC(Sakaguchi等人,2005)和大鼠(Yoshimura等人,2005)相比,滑膜MSC具有更好的增殖和软骨形成潜能> et al。,2007)。此外,施用用于骨软骨缺损的滑膜MSC促进兔子中的软骨再生(Koga等人,2008)和猪模型(Nakamura等人,2012) 。在2008年,我们开始了人类的临床试验,并通过磁共振成像获得令人满意的症状和再生软骨的结果(Sekiya等人,2015)。我们还利用滑膜MSC在大鼠中进行了半月板再生的多个研究线(Horie等人,2009; Horie等人,2012; Katagiri等人al。,2013; Okuno等人,2014; Ozeki等人,2015)。在本文中,我们演示了如何从大鼠膝关节收获包括髌下脂肪垫的滑膜,并描述大鼠滑膜MSC的分离和培养技术。
