Randomized trial shows functional recovery in Parkinsonian rats using cryopreserved dopaminergic progenitors, suggesting enhanced treatment options.

This research aims to enhance the differentiation of dopaminergic progenitors from human iPSCs for improved Parkinson's disease treatment.
Developed an optimized protocol for converting iPSCs into midbrain dopaminergic neurons.
Applied n-butylidenephthalide to reduce pluripotency genes and promote neurite outgrowth.
Transplanted cryopreserved dopaminergic progenitors into immunodeficient mice and 6-OHDA rats.
71% of iPSCs successfully differentiated into midbrain dopaminergic neurons with burst dopamine secretion.
No teratomas or neural tumors observed in immunodeficient mice within 24 weeks post-implantation.
Significant functional recovery in 6-OHDA PD rats observed within eight weeks after transplantation.

Chang et al. (2026) studied this question.
