Localization of pepsinogen (A and C) and cellular differentiation of pepsinogen-synthesizing cells in the human gastric mucosa.


The localization of pepsinogens (PG A and PG C) was studied intracellularly in human gastric biopsies embedded in Lowicryl K4M, using affinity-purified antibodies and protein A-gold. The homogeneous secretory granules of the chief cells contained both PG A and PG C, as was proved by serial sections. Identical reaction was also seen in the core of the… (More)
