Objective: In our previous study, we reported that valproic acid effects gliogenesis and increases the number of glial precursor cells during the early postnatal period.
Methods: As an ongoing study, using Immunoblotting analysis, we checked the level of glial protein and glial-derived factor markers in the frontal cortex of a rat brain at PND 21.
Results: The finding of the study suggests that, in the VPA group (p<0.05), early exposure induces increased precursor cell proliferation in the cortex and, later on, the expression level of glial protein cells was significantly increased.
Conclusion: Therefore we suggest that, alter gliogenesis and abnormal number of glial cells modulate the neurobiological dysfunction and induces the risk of neurodevelopmental disorders.
