Immunolocalization of Gas7 in the Subgranular Zone of Mice Hippocampus

It is established that neural stem cells (NSC) reside in the hippocampal subgranular zone (SGZ) and contribute to neurogenesis throughout life. Although the molecular events that regulate hippocampal neural stem cell differentiation are known, the precise mechanism is undefined. Here, the role of growth arrest specific 7 (Gas7) protein in SGZ neural progenitor cell differentiation was studied. Immunoblotting and immunohistochemistry for Gas7 were performed on 12 weeks old mice hippocampus. The results displayed a strong signal for Gas7 protein in the mice hippocampal tissue and SGZ cells, therefore suggesting that Gas7 might have a role in neural progenitor cell differentiation in SGZ.
