Gastric tuft cell

One key to understanding the role of tuft cells is that they share many characteristics with chemosensory cells in taste buds. For instance, they express many taste receptors and taste signaling apparatus. This might suggest that tuft cells could function as chemoreceptive cells that can sense many chemical signals around them. However, with more new research suggests that tuft cells can also be activated by the taste receptor apparatus. These can also be triggered by … WebGastric stem cells represent an adult stem cell population residing in the stomach tissues with high proliferative potential, which enables efficient stomach epithelium regeneration and repair. Following the comprehensive investigation of intestinal stems cells, the identity of gastric stem cells is being explored.
