There's Life After Radiation for Brain Cells. Johns Hopkins researchers suggest neural stem cells may regenerate after anti-cancer treatment. Release Date: August 12, 2013. Scientists have long believed that healthy brain cells, once damaged by radiation designed to kill brain tumors, cannot regenerate.
The key player in acid secretion is a H+/K+ ATPase or proton pump located in the cannalicular membrane. 1  This ATPase is magnesium-dependent, and not inhibitable by ouabain. The current model for explaining acid secretion is as follows: 2  Hydrogen ions are generated within the parietal cell from dissociation of water.
