Core Tip
Core tip: The different distributions of interstitial cells of Cajal (ICCs) and platelet-derived growth factor receptor-α positive (PDGFRα+) cells in the different parts of the colon result in a pressure gradient in the colon that propels the feces to the anus. Nitric oxide (NO) is mainly involved in the regulation of contraction through ICCs, and purine mainly participates in relaxation through PDGFRα+ cells. The regulation of the inhibitory transmitter NO and purine through the two kinds of interstitial cells (ICCs and PDGFRα+ cells) is very important for rhythmic colonic migrating motor complexes, which are the main driving force underlying colon transit.
