韩国延世大学Dong-Wook Kim团队的研究开发出了hESC来源的多巴胺祖细胞治疗帕金森病的1/2a期临床试验。相关论文于2025年10月13日发表在《细胞》杂志上。
该课题组从人胚胎干细胞中获得了高纯度的多巴胺能祖细胞(A9-DPCs),并在一项针对PD患者的单中心、开放标签、剂量递增的1/2a期试验(NCT05887466)中评估了它们的安全性和实验性有效性。12例中重度PD患者接受低剂量(315万个细胞,n = 6)或高剂量(630万个细胞,n = 6)免疫抑制的A9-DPC双侧壳核移植。未观察到剂量限制性毒性或移植物相关不良事件。12个月时,停药期运动障碍学会统一帕金森病评定量表(MDS-UPDRS)第三部分评分和Hoehn和Yahr分期均有所改善,高剂量组运动改善更大。多巴胺转运体正电子发射断层扫描(PET)成像显示,移植后高剂量组后壳核摄取增加,摄取更大,支持移植物存活。这些结果表明,双侧A9-DPC移植是安全的,并可能改善PD患者的帕金森运动症状。
据了解,长期以来,帕金森病(PD)一直被认为是细胞替代疗法的合适候选者。

Abstract: Parkinson’s disease (PD) has long been considered an appropriate candidate for cell replacement therapy. We generated high-purity dopaminergic progenitors (A9-DPCs) from human embryonic stem cells and evaluated their safety and exploratory efficacy in a single-center, open-label, dose-escalation phase 1/2a trial (NCT05887466) for PD patients. Twelve patients with moderate-to-severe PD received bilateral putamen transplantation of low-dose (3.15 million cells; n = 6) or high-dose (6.30 million cells; n = 6) A9-DPC with immunosuppression. No dose-limiting toxicities or graft-related adverse events were observed. At 12 months, off-medication Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) part III scores and Hoehn and Yahr stage improved, with greater motor improvements in the high-dose group. Dopamine transporter positron emission tomography (PET) imaging showed increased posterior putamen uptake with greater uptake in the high-dose group after transplantation, supporting graft survival. These findings indicate that bilateral transplantation of A9-DPC is safe and may improve parkinsonian motor symptoms in patients with PD.
