Synthetic mRNA-based approaches have many desirable features for cell differentiation strategies. Here we investigated whether epigenetic modifications can reverse the regional restriction of mouse adult brain subventricular zone (SVZ) NSCs. To certify the effect of ACTA2 downregulation on NSC differentiation, immunoblotting was firstly used to determine the expression of three main neural cell markers derived from NSC (-III-Tubulin for neurons, Olig2 for oligodendrocytes, and GFAP for astrocyte). Neural stem cells (NSCs) lose their competency to generate region-specific neuronal populations at an early stage during embryonic brain development. Neural stem cells (NSCs) persist in the dentate gyrus of the hippocampus into adulthood and are essential for both neurogenesis and neural circuit integration. Understanding how neuronal diversity is achieved within the cerebral cortex remains a major challenge in neuroscience.
