Abstract (original English)

Neural stem cells have shown great potential in the therapy of neurodegenerative diseases such as Parkinson's disease (PD), because of their ability to differentiate into various types of neural cells and substitute for damaged neurons. Their clinical application is, however, impeded by limitations such as low survival rates following transplantation, low efficiency of differentiation, the potential for tumorigenesis, and the risk of immune rejection by the host. Adipose-derived stem cells (ADSCs) have become increasingly popular as an alternative tool in regenerative medicine due to their accessibility, multipotency, and low immunogenicity. The recent advance in inducing ADSCs into neural stem cell-like cells (iNSCs) opens up a new avenue for the treatment of PD by restoring dopaminergic neuron populations. Here, the biological characteristics, induction protocols, molecular mechanisms, and prospective applications of ADSCs in neural repair are summarized systematically. We also covered current technical challenges, such as differentiation protocol optimization and functional integration, and future perspectives, including biomaterial and gene editing applications to enhance ADSC-based therapies. With these challenges met, ADSCs hold excellent potential for advancing personalized and combination therapies for neurodegenerative diseases.
