[Abstract]  Human endometrial stem cell/stromal cells (hEnSCs) are isolated from endometrium or menstrual blood and are recognized as a valuable cell type in tissue engineering and cell therapy. Furthermore, hEnSCs, which have CD90 (a mesenchymal marker), CD105 (endoglin), CD44, CD146 (endometrial stem cell markers) and lack CD31 (Endothelial marker), CD34 (hematopoietic marker) and CD133 on the cell surface, are a new source of mesenchymal stem/stromal cells. Additionally, these cells can be encapsulated into self-assembling peptide nanofibers as a 3D scaffold for applications in the treatment of neurodegenerative diseases. Here, we describe a protocol to isolate hEnSCs from endometrium or menstrual blood. [摘要]  人类子宫内膜干细胞/基质细胞(hEnSCs)是从子宫内膜或经血中分离出来的,在组织工程和细胞治疗中被公认为有价值的细胞类型。 此外,在细胞表面具有CD90(间充质标记),CD105(内皮糖蛋白),CD44,CD146(子宫内膜干细胞标记)和缺乏CD31(内皮标记),CD34(造血标记)和CD133的hEnSCs是新的 间充质干细胞/基质细胞的来源。 此外,这些细胞可以封装成自组装肽纳米纤维作为三维支架应用于治疗神经退行性疾病。 在这里,我们描述了从子宫内膜或经血中分离hEnSC的方案。

【背景】正在研究细胞替代治疗,作为治疗神经退行性疾病(如阿尔茨海默病,中风和脊髓损伤)的新策略(Tavakol等人,2014b; 2015; 2016a和2016c)。子宫内膜干细胞/基质细胞(hEnSCs)可以从经血(Azedi等人,2014和2017)和子宫内膜分离。这些细胞具有脂肪形成(Khanmohammadi等人,2014),成骨(Darzi等人,2012)和软骨形成(Kazemnejad等人, >,2012)分化潜力。此外,这些细胞可以与支架组合用作组织工程应用中智能细胞支架的成分(Tavakol等人,2014a; 2016b和2017)。值得注意的是,诸如外来体,微泡和其他组分的细胞区室被认为比使用全细胞的治疗更安全。 ...

[Abstract]  Chemoresistance is one of the special properties of cancer stem cells, which is the main cause of chemotherapy failure and plays an important role in the recurrence of various cancers including osteosarcoma. The most widely used assay for evaluating chemoresistance is the modified cell proliferation assay. An equal number of cells are seeded onto 96-well culture plates or 24-well plates, and then different concentrations of anti-cancer drugs are added into each well. After that, measure the cell density or cell activity to observe the effect of anti-cancer drugs to cancer cells or cancer stem cells. The chemoresistance of cells is stronger, the cell density or cell activity is higher. Here, we describe chemosensitivity assays for osteosarcoma cells and osteosarcoma stem-like cells.
[摘要]  化学抗性是癌症干细胞的特殊性质之一,其是化疗失败的主要原因,并且在各种癌症(包括骨肉瘤)的复发中起重要作用。 最广泛使用的用于评价化学抗性的测定法是修饰的细胞增殖测定法。 将等量的细胞接种到96孔培养板或24孔板上,然后将不同浓度的抗癌药物加入每个孔中。 之后,测量细胞密度或细胞活性,观察抗癌药物对癌细胞或癌症干细胞的作用。 细胞的化学抗性更强,细胞密度或细胞活性更高。 在这里,我们描述了骨肉瘤细胞和骨肉瘤干样细胞的化学敏感性测定。

[Abstract]  Human umbilical vein endothelial cells (HUVEC) can be isolated from normal human umbilical veins, and are responsive to cytokine stimulation by expressing cell adhesion molecules. These cell systems are commonly used for physiological and pharmacological investigations, such as macromolecule transport, blood coagulation, and angiogenesis. This protocol describes the generation of HUVECs. [摘要]  人脐静脉内皮细胞(HUVEC)可以从正常人脐静脉中分离,并且通过表达细胞粘附分子对细胞因子刺激响应。 这些细胞系统通常用于生理学和药理学研究,例如大分子运输,血液凝固和血管生成。 该协议描述了HUVEC的产生。
