1	Do L-carnitine-induced neuronal cells from ADSCs function equivalently to nativ… While the study demonstrates increased neurogenic markers, it doesn't assess whether these differentiated cells exhibit functional neuronal properties like syna… gap-pubmed-20260410-192420-21b34ed5	open	0.820	neuroregeneration	2026-04-10	Open →
2	What determines the distinct lineage commitment of NG2+ vs Tbx18+ pericyte subt… The study reveals that NG2+ pericytes preferentially generate neurons while Tbx18+ pericytes produce endothelial cells, fibroblasts, and microglia after stroke,… gap-pubmed-20260411-083138-d4ebb86e	open	0.820	neuroregeneration	2026-04-11	Open →
3	Why do MSC-EVs demonstrate superior regenerative effects compared to HEK293-EVs… The abstract reports MSC-EVs outperformed HEK-EVs but doesn't explain the mechanistic basis for this difference. Understanding this could inform optimal EV sour… gap-pubmed-20260410-181230-2c24d2bb	open	0.800	neuroregeneration	2026-04-10	Open →
4	How does L-carnitine simultaneously activate both PKA and Wnt/β-catenin pathway… The study shows L-carnitine activates two distinct signaling pathways but doesn't explain the molecular mechanism linking L-carnitine to both pathways or whethe… gap-pubmed-20260410-192420-fc83b09b	open	0.800	neuroregeneration	2026-04-10	Open →
5	Does the CaMKII/CaN switch mechanism operate in axon regeneration after injury? The findings demonstrate this calcium switch in developmental pathfinding, but whether the same mechanism controls regenerating axons in mature nervous systems … gap-pubmed-20260410-173341-1583baa0	open	0.780	neuroregeneration	2026-04-10	Open →
