细胞移植具有技术容易,可将细胞放置到免疫学和生理学上有利的部位,移植前易于进行细胞培养,并且能长期冰冻保存细胞和使用方便等优点。其主要理论基础是妊娠早期的胎儿组织免疫学上的“不成熟性”,应用人类胎儿组织进行临床研究和治疗某些疾病(如血液、内分泌、代谢和神经性疾病)在伦理方面不受谴责。胎儿造血千细胞、胰岛细胞和产生多巴胺能细胞的实验工作,提示胎儿在红细胞移植领域中可迅速起重要作用。
Cell transplantation is technically easy, placing cells in immunologically and physiologically favorable sites, facilitating cell culture prior to transplantation, and long-term cryopreservation of cells and ease of use. Its rationale is based on the immunological “immaturity” of fetal tissues in early pregnancy, ethical aspects of using human fetal tissue for clinical research and the treatment of certain diseases (such as blood, endocrine, metabolic and neurological diseases) . Fetal hematopoietic stem cells, hematopoietic stem cells, and the production of dopaminergic cells suggest that fetuses may play an important role rapidly in the field of erythrocyte transplantation.
