Haematopoietic stem cells in umbilical cord blood are an attractive target for gene therapy of inborn errors of metabolism. Three neonates with severe combined immunodeficiency were treated by retroviral-mediated transduction of the CD34+ cells from their umbilical cord blood with a normal human adenosine deaminase complementary DNA followed by autologous transplantation. The continued presence and expression of the introduced gene in leukocytes from bone marrow and peripheral blood for 18 months demonstrates that umbilical cord blood cells may be genetically modified with retroviral vectors and engrafted in neonates for gene therapy.
脐带血中的造血干细胞是先天性代谢缺陷基因治疗的一个有吸引力的靶点。三名患有严重联合免疫缺陷的新生儿接受了如下治疗:从他们的脐带血中提取CD34+细胞,用正常人腺苷脱氨酶互补DNA进行逆转录病毒介导的转导,然后进行自体移植。导入的基因在骨髓和外周血白细胞中持续存在并表达达18个月,这表明脐带血细胞可用逆转录病毒载体进行基因改造,并植入新生儿体内用于基因治疗。
