干细胞是修复神经损伤中受损神经元和神经胶质细胞以及替代神经退行性疾病中死亡细胞的有希望的来源。基于干细胞的治疗的一个重要步骤是产生大量的干细胞并开发可靠的培养条件以指导特定神经元和神经胶质亚型的有效分化。人脐带和脐带血(UCB)是多种干细胞的丰富来源,包括造血干细胞、间充质干细胞、非限制性体干细胞和胚胎样干细胞。人UC/UCB衍生细胞能够产生多种细胞类型的神经谱系。研究表明,UCB和UCB衍生的细胞可以在缺血性脑损伤和脊髓损伤的动物模型中的损伤部位存活,并促进局部神经元和胶质细胞的存活和防止细胞死亡。人UCB易于收获和纯化。此外,与胚胎干细胞不同,人类UCB的使用不受伦理困境的限制。因此,人脐带血是一个有吸引力的干细胞来源,用于修复神经损伤。
Stem cells are promising sources for repairing damaged neurons and glial cells in neural injuries and for replacing dead cells in neurodegenerative diseases. An essential step for stem cell-based therapy is to generate large quantities of stem cells and develop reliable culture conditions to direct efficient differentiation of specific neuronal and glial subtypes. The human umbilical cord and umbilical cord blood (UCB) are rich sources of multiple stem cells, including hematopoietic stem cells, mesenchymal stem cells, unrestricted somatic stem cells, and embryonic-like stem cells. Human UC/UCB-derived cells are able to give rise to multiple cell types of neural lineages. Studies have shown that UCB and UCB-derived cells can survive in injured sites in animal models of ischemic brain damage and spinal cord injuries, and promote survival and prevent cell death of local neurons and glia. Human UCB is easy to harvest and purify. Moreover, unlike embryonic stem cells, the use of human UCB is not limited by ethical quandaries. Therefore, human UCB is an attractive source of stem cells for repairing neural injuries.
