    Abstract:
    The expressions of mRNAs for pituitary adenylate cyclase-activating polypeptide (PACAP), vasoactive intestinal peptide (VIP), and their receptors (PAC1, VPAC1 and VPAC2) were examined in the five steps of the in vitro neuronal culture model of embryonic stem (ES) cell differentiation. mRNAs for PACAP, VIP, PAC1 receptor, and VPAC2 receptor were moderately expressed in neural stem cell-enriched cultures, while VPAC1 receptor mRNA was most prominently expressed in embryoid bodies (EBs). The expression of PAC1 receptor mRNA was further upregulated after terminal differentiation into neurons. In contrast, the expressions of PAC1 receptor and PACAP mRNAs were markedly decreased after glial differentiation. These results suggest that this in vitro neuronal culture system will be a useful model for future studies on the functional role of the PACAPergic system during different stages of neuronal development.
