Neural stem cell proliferation pathway (NSC proliferation pathway)

The neural stem cell (NSC) proliferation pathway is a collective term for the signaling networks, including Notch, Wnt, and Sonic Hedgehog (Shh), that regulate the self-renewal and expansion of neural progenitor cells (Source: Nature Reviews Neuroscience, 2014). These pathways are vital for the development of the central nervous system and remain active in adult brain regions such as the subventricular zone and the dentate gyrus of the hippocampus (Source: NIH, National Institute of Neurological Disorders and Stroke). In clinical contexts, the pathway is a focal point for regenerative medicine, where drugs like metformin and fluoxetine are studied for their ability to stimulate endogenous repair following stroke or in neurodegenerative conditions (Source: Cell Stem Cell, 2012; Science, 2003). Conversely, the pathway is often pathologically hijacked in brain tumors, such as glioblastoma, where it drives the proliferation of cancer stem cells (Source: PubMed, PMID: 28835470). Therapeutic targeting requires high precision to avoid the risk of oncogenesis or ectopic neurogenesis while ensuring effective delivery across the blood-brain barrier (Source: Journal of Clinical Investigation, 2017). Monitoring these processes typically involves the use of biomarkers like Nestin and SOX2 to identify progenitor populations and Ki-67 to measure mitotic activity (Source: UniProt).
