Calderon 12 demonstrated that the endocrine pancreas of newborn rats with moderate diabetes has large islets with increased insulin production, as observed by immunohistochemistry using specific antibodies. The lack of insulin production by the fetal pancreas at the end of pregnancy does not permit the removal of glycogen stores from the placenta and the fetus does not grow in an adequate manner.
