Differentiation of Human Induced Pluripotent Stem Cells (iPS Cells) and Embryonic Stem Cells (ES Cells) into Dendritic Cell (DC) Subsets

[Abstract]  Induced pluripotent stem cells (iPS cells) are engineered stem cells, which exhibit properties very similar to embryonic stem cells (ES cells; Takahashi and Yamanaka, 2016). Both iPS cells and ES cells have an extraordinary self-renewal capacity and can differentiate into all cell types of our body, including hematopoietic stem/progenitor cells and dendritic cells (DC) derived thereof. This makes iPS cells particularly well suited for studying molecular mechanisms of diseases, drug discovery and regenerative therapy (Grskovic et al., 2011; Bellin et al., 2012; Robinton and Daley, 2012).

DC are the major antigen presenting cells of the immune system and thus they are key players in modulating and directing immune responses (Merad et al., 2013). DC ...
[摘要]  诱导的多能干细胞(iPS细胞)是工程干细胞,其表现出与胚胎干细胞(ES细胞,Takahashi和Yamanaka,2016)非常相似的性质。 iPS细胞和ES细胞都具有非凡的自我更新能力,可以分化成我们身体的所有细胞类型,包括造血干细胞/祖细胞和源自其的树突状细胞(DC)。这使得iPS细胞特别适用于研究疾病,药物发现和再生治疗的分子机制(Grskovic等人,2011; Bellin等人,2012; Robinton和Daley,2012)。
  DC是免疫系统的主要抗原呈递细胞,因此它们是调节和引导免疫应答的关键参与者(Merad等人,2013)。 DC巡逻外周和界面组织(例如,肺,肠和皮肤)以检测入侵的病原体,并且在激活时,它们迁移到淋巴结以激活和引发淋巴细胞。
  DC包含具有功能专门子集的表型异质家族(Schlitzer和Ginhoux,2014)。通常,经典DC(cDC)和浆细胞样DC(pDC)是分别表现出典型的和等离子体细胞样的DC形态。 cDC识别许多病原体并在激活后分泌促炎细胞因子,而pDC专门检测细胞内病原体并分泌I型干扰素(Merad等,2013; Schlitzer和Ginhoux,2014)。在被称为CD141 Clec9a + cDC1和CD1c + ...

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。
