• To discuss the advantages and challenges of using SMs in preclinical and clinical settings.
• To evaluate the potential of SMs for stem cell therapy in neurological disorders.

Main Methods:

• Literature review of recent studies on SMs for neuronal differentiation.
• Analysis of SMs' impact on key developmental signaling pathways (WNT, Notch, Shh, etc.).
• Examination of preclinical research pitfalls and clinical-stage studies.

Main Results:

• Small Molecules (SMs) offer a promising approach to shorten induction time and increase neuronal differentiation rates.
• SMs effectively modulate essential developmental pathways regulating neuronal maturation.
• Preclinical research highlights challenges, while some SM-based therapies have advanced to clinical trials.

Conclusions:
