Description

The study reveals that NG2+ pericytes preferentially generate neurons while Tbx18+ pericytes produce endothelial cells, fibroblasts, and microglia after stroke, but the molecular mechanisms governing this subtype-specific fate determination remain unexplained. Understanding these determinants could enable targeted manipulation of specific pericyte populations for therapeutic benefit.
