Neural stem cell (NSC) proliferation and differentiation pathways (NSC pathways)

Neural stem cell (NSC) proliferation and differentiation pathways represent a complex network of signaling cascades, including Notch, Wnt, Sonic Hedgehog (Shh), and Bone Morphogenetic Protein (BMP), that govern the development and maintenance of the central nervous system [PMID: 25131981]. These pathways are essential for balancing NSC self-renewal with the generation of neurons and glial cells during both embryonic development and adult neurogenesis in specific brain niches [PMID: 22498671]. Dysregulation of these processes is a hallmark of various pathologies; for instance, reduced signaling can lead to neurodegenerative decline or impaired recovery after stroke, while overactivation is frequently linked to the progression of brain tumors such as glioblastoma and medulloblastoma [PMID: 30241164]. Pharmacological strategies often target specific components of these pathways, such as using Smoothened inhibitors to block Shh signaling in cancer or GSK-3 inhibitors to enhance Wnt signaling for regenerative purposes [PMID: 28938084]. However, because these pathways are fundamental to many physiological processes across different tissues, therapeutic intervention carries significant risks of oncogenesis and systemic toxicity [PMID: 23643297].
