Exercise with induced pluripotent stem cells enhances Wnt1-Lmx1a signaling and dopaminergic neurogenesis to alleviate Parkinsonian symptoms

This article focused on the recent contribution by Jiang <i>et al</i>, who demonstrated that voluntary exercise can significantly potentiate the effects of induced pluripotent stem cell transplantation in a Parkinson's disease (PD) model through activation of the Wnt1-Lmx1a signaling cascade. Jiang <i>et al</i>'s findings highlight the role of exercise as a molecular modulator of neurogenesis and support the development of integrated strategies combining physical activity, stem cell transplantation, and biomaterials to improve outcomes in PD. We highlight exercise as a molecular modulator that fosters a neurogenic milieu, recommend examining additional developmental signals (sonic hedgehog, fibroblast growth factor 8, bone morphogenetic protein), and suggest biomaterial-based strategies to support graft survival and integration. We also stress the need to optimize exercise regimens in relation to transplantation, framing these insights within a translational strategy for advancing regenerative therapies in PD.
