Human Schwann cells (hSCs) can be isolated directly from peripheral nerve and cultured using methods similar to those used for SCs from other species. Yet, important interspecies differences are revealed when the primary or expanded hSCs are compared to their nonhuman counterparts. This review addresses the special properties of nerve-derived hSCs that have resulted to date from both in vitro studies and in vivo research on cell transplantation in animal models and human subjects. A consensus has yet to emerge about the essential attributes of cultured normal hSCs. Thus, an emphasis is placed on the importance of validating hSC cultures by means of purity, identity, and biological activity to reliably use them as in vitro models of the SC phenotype and cell therapy products for injury repair. Combining traditional immunological methods, high-resolution omics approaches, and assorted cell-based assays is so far the best approach to unequivocally identify hSC populations obtained by direct isolation or derivation from stem cells. Special considerations are required to understand and manage the variability and heterogeneity proper of donor batches, as well as to evaluate risk factors. This is particularly important if the intended use of the hSCs is implantation in the human body, diagnosis of disease, or drug testing aimed at targeting any aspect of SC function in human patients. To conclude, in view of their unique properties, new concepts and methods are needed to better understand the biology of hSCs and exploit their full potential in basic science and regenerative medicine.

人类雪旺细胞的特性:体外培养和移植研究的经验教训。

人类雪旺氏细胞(hSCs)可以直接从周围神经中分离出来,并使用与其他物种的SCs类似的方法进行培养。然而,当将原代或扩展的造血干细胞与非人类的造血干细胞进行比较时,就会发现重要的种间差异。这项审查解决了迄今为止在动物模型和人类受试者的细胞移植的体外研究和体内研究中所产生的神经源性hSCs的特殊性质。关于培养的正常人造血干细胞的基本属性尚未达成共识。因此,重点放在通过纯度,特性和生物学活性验证hSC培养物以将其可靠地用作SC表型和损伤修复细胞治疗产品的体外模型的重要性。结合传统的免疫学方法,迄今为止,高分辨率的组学方法和基于细胞的分类分析是明确鉴定通过直接分离或衍生自干细胞获得的hSC群体的最佳方法。需要特别考虑才能理解和管理供体批次的变异性和异质性,以及评估风险因素。如果hSC的预期用途是植入人体,诊断疾病或针对人患者SC功能的任何方面的药物测试,则这尤其重要。总之,鉴于其独特的特性,需要新的概念和方法来更好地了解hSC的生物学,并充分利用其在基础科学和再生医学中的潜力。迄今为止,基于细胞的分类分析是明确鉴定通过直接分离或衍生自干细胞获得的hSC群体的最佳方法。需要特别考虑才能理解和管理供体批次的变异性和异质性,以及评估风险因素。如果hSC的预期用途是植入人体,诊断疾病或针对人类患者SC功能的任何方面的药物测试,则这尤其重要。总之,鉴于其独特的特性,需要新的概念和方法来更好地了解hSC的生物学,并充分利用其在基础科学和再生医学中的潜力。迄今为止,基于细胞的分类分析是明确鉴定通过直接分离或衍生自干细胞获得的hSC群体的最佳方法。需要特别考虑才能理解和管理供体批次的变异性和异质性,以及评估风险因素。如果hSC的预期用途是植入人体,诊断疾病或针对人类患者SC功能的任何方面的药物测试,则这尤其重要。总之,鉴于其独特的特性,需要新的概念和方法来更好地了解hSC的生物学,并充分利用其在基础科学和再生医学中的潜力。需要特别考虑才能理解和管理供体批次的变异性和异质性,以及评估风险因素。如果hSC的预期用途是植入人体,诊断疾病或针对人类患者SC功能的任何方面的药物测试,则这尤其重要。总之,鉴于其独特的特性,需要新的概念和方法来更好地了解hSC的生物学,并充分利用其在基础科学和再生医学中的潜力。需要特别考虑才能理解和管理供体批次的变异性和异质性,以及评估风险因素。如果hSC的预期用途是植入人体,诊断疾病或针对人类患者SC功能的任何方面的药物测试,则这尤其重要。总之,鉴于其独特的特性,需要新的概念和方法来更好地了解hSC的生物学,并充分利用其在基础科学和再生医学中的潜力。
