the majorty of B cell decreases the blood sugar and secretes insulin needed for your liver etc aka the glycogen etc.. when these cells depress the diabetic symptoms occur.its the glucose that makes the is what makes the secretion of insulin.. beta cells arrive in order to change/convert glucose so its mostly the glucose thats important for the stimulation of glucose. the injections you get are used to stimulate the b cell building a film around the other cells but these cells have whats called a golgi transport and with the right medical science you can stimulate B reproduction because the cells actually MORPH to become B cells. inside the nucleus of the cell within the cytoplasm material.med science often looks at the direct cause blaming a false suspect when often times they are like police near the scene of the accident monitoring a situation. so the treatment your getting is merely a back door approach rather than a direct hit to the sources.

There was a documentary (or news article I forget which) just this weekend on some pigs in NZ that are very pure blood and have proven extremely successful in diabetic treatments...
