[Abstract] To investigate underlying mechanism of chondrogenic hypertrophy, we need proper in vitro hypertrophic model of mesenchymal stem cells (MSCs). This protocol describes our defined method for induction of in vitro chondrogenic hypertrophy of human umbilical cord blood-derived MSCs (hUCB-MSCs). By adding thyroid hormone (T3; triiodothyronine) and minimum osteogenic-inducing factors to culture medium, we could induce hypertrophy of hUCB-MSCs in vitro. Hypertrophic induction was validated using immunohistochemical analysis, Western blotting and reverse transcriptase polymerase chain reaction.
[摘要] 为了研究软骨形成性肥大的基础机制，我们需要适当的体外间充质干细胞（MSC）的增生模型。该协议描述了我们定义的诱导人脐带血衍生的MSC（hUCB-MSC）的体外软骨形成性肥大的方法。通过将甲状腺激素（T3;三碘甲状腺原氨酸）和最小成骨诱导因子添加到培养基中，我们可以在体外诱导hUCB-MSCs的增生。使用免疫组织化学分析，Western印迹和逆转录酶聚合酶链反应验证肥大性诱导。

[Abstract] Bone marrow-derived mesenchymal stromal stem cells (BMSCs) are a promising cell source for treating articular cartilage defects (Bornes et al., 2014). BMSCs can be seeded within porous biomaterial scaffolds that support three-dimensional cell organization, chondrogenic differentiation and extracellular matrix deposition for the creation of engineered cartilage. This protocol describes our defined methods for isolation and expansion of human and ovine BMSCs, seeding of BMSCs within porous scaffolds and in vitro chondrogenic differentiation (Adesida et al., 2012; Bornes et al., 2015).
[摘要] 骨髓来源的间充质干细胞（BMSCs）是治疗关节软骨缺陷的有希望的细胞来源（Bornes等人，2014）。 BMSCs可以种植在支持三维细胞组织，软骨形成分化和细胞外基质沉积的多孔生物材料支架中，用于创建工程化软骨。 该方案描述了我们定义的用于分离和扩增人和绵羊BMSCs，在多孔支架内接种BMSCs和在体外软骨形成分化的方法（Adesida等人，2012; Bornes et al。，2015）。

[Abstract] Glioma Associated Stem Cells (GASCs) represent a population of non-tumorigenic multipotent stem cells hosted in the microenvironment of human gliomas. In vitro, these cells are able, through the release of exosomes, to increase the biological aggressiveness of glioma-initiating cells. The clinical importance of this finding is supported by the strong prognostic value associated with the GASCs surface immunophenotype thus suggesting that this patient-based approach can provide a groundbreaking method to predict prognosis and to exploit novel strategies that target the tumor stroma (Bourkoula et al., 2014).
[摘要] 胶质瘤相关干细胞（GASC）代表在人类神经胶质瘤的微环境中存在的非致瘤性多能干细胞群体。 在体外，这些细胞能够通过外来体的释放增加胶质瘤起始细胞的生物攻击性。 该发现的临床重要性得到与GASCs表面免疫表型相关的强预后价值的支持，因此表明这种基于患者的方法可以提供开创性的方法来预测预后并开发靶向肿瘤基质的新策略（Bourkoula等人， et al。，2014）。
