Localization of P2Y1 purinoceptor transcripts in the rat penis and urinary bladder.

Abstract

These results indicate that mRNAs for P2Y1 purinoceptor are expressed in detrusor smooth muscle cells and blood vessels of rat urinary bladder. However, in penis, this receptor is expressed in endothelial cells which lines the lacunar space and blood vessels, but not expressed in corpus cavernosum smooth muscle cells and urethra.
