Neural crest cells (NCCs) are an embryonic migratory cell population with the ability to differentiate into a wide variety of cell types that contribute to the craniofacial skeleton, cornea, peripheral nervous system, and skin pigmentation. This ability suggests the promising role of NCCs as a source for cell-based therapy. Although several methods have been used to induce human NCCs (hNCCs) from human pluripotent stem cells (hPSCs), such as embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), further modifications are required to improve the robustness, efficacy, and simplicity of these methods. Chemically defined medium (CDM) was used as the basal medium in the induction and maintenance steps. By optimizing the culture conditions, the combination of the GSK3β inhibitor and TGFβ inhibitor with a minimum growth factor (insulin) very efficiently induced hNCCs (70-80%) from hPSCs. The induced hNCCs expressed cranial NCC-related genes and stably proliferated in CDM supplemented with EGF and FGF2 up to at least 10 passages without changes being observed in the major gene expression profiles. Differentiation properties were confirmed for peripheral neurons, glia, melanocytes, and corneal endothelial cells. In addition, cells with differentiation characteristics similar to multipotent mesenchymal stromal cells (MSCs) were induced from hNCCs using CDM specific for human MSCs. Our simple and robust induction protocol using small molecule compounds with defined media enabled the generation of hNCCs as an intermediate material producing terminally differentiated cells for cell-based innovative medicine.
神经嵴细胞(NCCs)是一种胚胎迁移细胞群体,具有分化为多种细胞类型的能力,这些细胞类型对颅面骨骼、角膜、外周神经系统和皮肤色素沉着有贡献。这种能力表明NCCs作为基于细胞治疗的来源具有广阔前景。尽管已经使用了多种方法从人多能干细胞(hPSCs),如胚胎干细胞(ESCs)和诱导多能干细胞(iPSCs)中诱导人神经嵴细胞(hNCCs),但仍需要进一步改进以提高这些方法的稳健性、有效性和简便性。化学限定培养基(CDM)被用作诱导和维持步骤的基础培养基。通过优化培养条件,将GSK3β抑制剂和TGFβ抑制剂与最低生长因子(胰岛素)组合,能非常有效地从hPSCs中诱导出hNCCs(70 - 80%)。诱导出的hNCCs表达颅神经嵴相关基因,并在补充有EGF和FGF2的CDM中稳定增殖,至少传代10次,主要基因表达谱未观察到变化。对外周神经元、神经胶质细胞、黑素细胞和角膜内皮细胞的分化特性进行了确认。此外,使用针对人骨髓间充质干细胞(MSCs)的CDM从hNCCs中诱导出了具有与多能间充质基质细胞(MSCs)相似分化特征的细胞。我们使用小分子化合物和限定培养基的简单且稳健的诱导方案,能够生成hNCCs作为一种中间材料,用于为基于细胞的创新医学产生终末分化细胞。
