Developmental changes of expression of non-muscle (beta and gamma) actin mRNAs in the central nervous system studied by in situ hybridization.

In situ hybridization of mRNAs for beta- and gamma-cytoplasmic non-muscle actin in the mouse central nervous system revealed their differential expression correlating with the developmental stages. Most intense expression of both isoactin mRNAs at the specific postnatal developmental stage was observed in pyramidal cells of cerebral cortex. Purkinje cells of the cerebellar cortex and facial motor neurons.
