人类胚胎干细胞提供了进入人类发育最早阶段的途径,并可作为再生医学专门细胞的来源。因此,它成为至关重要的开发协议的胚胎干细胞定向分化为组织限制的前体。在这里,我们提供了从人胚胎干细胞中衍生无限数量的纯间充质前体的培养条件,并证明了向脂肪、软骨、骨和骨骼肌细胞的多谱系分化。我们的研究结果将有助于阐明胚胎干细胞分化过程中胚层特化的机制,并为将来的临床应用提供一个有效产生特化人类间充质细胞类型的平台。Lorenz Studer及其同事描述了使用胚胎干细胞来衍生间充质前体,然后衍生脂肪、软骨、骨和骨骼肌细胞。
Human embryonic stem cells provide access to the earliest stages of human development and may serve as a source of specialized cells for regenerative medicine. Thus, it becomes crucial to develop protocols for the directed differentiation of embryonic stem cells into tissue-restricted precursors. Here, we present culture conditions for the derivation of unlimited numbers of pure mesenchymal precursors from human embryonic stem cells and demonstrate multilineage differentiation into fat, cartilage, bone, and skeletal muscle cells. Our findings will help to elucidate the mechanism of mesoderm specification during embryonic stem cell differentiation and provide a platform to efficiently generate specialized human mesenchymal cell types for future clinical applications. Lorenz Studer and colleagues describe the use of embryonic stem cells to derive mesenchymal precursors and then fat, cartilage, bone, and skeletal muscle cells.
