Isolation and Primary Culture of Adult Human Adipose-derived Stromal/Stem Cells

[Abstract]  Adipose-derived stromal/stem cells (ASCs) are multipotent cells that can be isolated from adipose tissue. Studies have shown that cells have the capacity to self-renew and differentiate into adipocyte, chondrocyte, myocyte, and osteoblast lineages. Thus, significant interest regarding their use for regenerative purposes to restore aging or damaged tissue has grown in recent decades. These cells have also been shown to immunomodulate the microenvironment and secrete abundant growth factors, which minimize inflammation and aid repair and regeneration. ASCs can be readily isolated from the stromal vascular fraction (SVF) of lipoaspirates. Given their ease of accessibility, bountiful source, and potential application in regenerative medicine and tissue engineering, there is growing interest ... [摘要]  脂肪来源的基质/干细胞(ASCs)是可以从脂肪组织分离的多能细胞。研究表明,细胞具有自我更新和分化成脂肪细胞,软骨细胞,肌细胞和成骨细胞谱系的能力。因此,近几十年来,对再生用途恢复老化或损伤组织的兴趣越来越大。这些细胞也被证明可以免疫微环境并分泌丰富的生长因子,从而使炎症最小化并辅助修复和再生。 ASCs可以容易地从脂质体的基质血管分数(SVF)中分离出来。鉴于其易于获取,丰富的来源和在再生医学和组织工程中的潜在应用,对于ASC的表征和利用越来越感兴趣。该方案描述了从成人人类脂肪组织中分离的ASC以及用于培养维持的方法,包括扩增和低温保存。

背景 脂肪来源的基质/干细胞(ASCs)表现出干细胞领域的巨大潜力。根据造血干细胞移植的治疗奇迹,ASCs代表干细胞的未来,因为它们更容易获得源 - 脂肪组织。 ASCs自我更新和分化成各种组织谱系(包括脂肪细胞,软骨细胞,肌细胞和成骨细胞谱系)的能力允许恢复损伤的组织。另外,推测ASCs有可能在体外复制组织。器官将允许更容易获得新颖药物的评估,从而显着降低药物生产成本。然而,隔离,维护和冷冻保存过程中的不一致,禁止集体分析世界各地不同实验室的结果。用于分离和培养ASC的标准方案对于确保一致的数据分析是必要的。

[Abstract]  Antigen uptake by dendritic cells is the first key step towards induction of antigen-specific T-cell responses. This flow cytometry-based protocol describes the analysis of dendritic cell uptake of soluble antigens through two different mechanisms: non-specific macropinocytosis (using Lucifer Yelloy CH), and receptor-mediated endocytosis (using DQTM Ovalbumin). The protocol is generated based on data presented in Olivar et al. (2013). [摘要]  树突状细胞的抗原摄取是诱导抗原特异性T细胞应答的第一个关键步骤。 这种基于流式细胞术的方案描述了通过两种不同的机制分析树突状细胞摄取可溶性抗原:非特异性大细胞增多症(使用Lucifer Yelloy CH)和受体介导的内吞作用(使用DQ TM 卵清蛋白) 。 该方案是基于Olivar等人(2013)中提供的数据产生的。
