Pancreas
These images show two special histochemical stains used to distinguish among the different cell types in the islet of Langerhans. The aldehyde fuchsin method (left) stains insulin-secreting beta cells blue. The Gomori’s method (right) stains insulin-secreting beta cells light blue and glucagon-secreting alpha cells pink. Beta cells comprise about 70% of the islet cells, alpha cells about 20%. The remaining somtatostatin-secreting delta cells are not distinguished by these methods. 400x, 400x
