基因治疗可以分为体细胞基因治疗、生殖细胞基因治疗和增强细胞基因治疗。体细胞基因治疗(somaticcellgenetherapy)是应用体细胞基因工程技术将某个基因植入人体,从医学上校正该病人的遗传缺陷。生殖细胞基因治疗(germ-linegenetherapy)是将外源正常基因转入精子、卵子或受精卵 Gene therapy can be divided into somatic gene therapy, germ cell gene therapy and enhance cell gene therapy. Somatic cell gene therapy (somatic cell immunotherapy) is the application of somatic cell engineering to implant a gene into the human body to medically correct the patient’s genetic defects. Germ-line gene therapy (germ-line genetherapy) is the transfer of exogenous normal genes into sperm, eggs or fertilized eggs
