the immunohistochemical detection of six distinct sequences of proglucagon and its derivatives ( grpp , glicentin , glucagon-37 , glucagon-29 , glp1 , glp2 and mpgf ) in both intestinal l cells and pancreatic or gastric a cells of some mammals ( dog , man , guinea pig ) confirms that the two cell types produce the same proglucagon molecule , although the final step of its post-translational processing differs in the two cells .
