In this episode of "Got Guts" The Micro Version, Jill P. Smith highlights the recently published research titled "Implicating the cholecystokinin B receptor in liver stem cell oncogenesis." This investigation identified a novel pathway involving the activation of hepatic stem cells and liver oncogenesis. Receptor blockade or genetic disruption of the cholecystokinin-B receptor (CCK-BR) signaling pathway decreased the activation and proliferation of hepatic stem cells after liver injury without eliminating the regenerative capacity of healthy hepatocytes.   Article Citation: Implicating the cholecystokinin B receptor in liver stem cell oncogenesis Martha D.
