[The human renin-secreting cell. A morphological study].

The availability of specific antisera to renin and the techniques of immunocytochemistry have facilitated the microscope study of renin-secreting cells. These techniques have been used in recent studies in the developing kidney as well as in both normal and pathological adult kidney. This work has clarified the close relationship between myoepithelioid cell and the blood vessel. The use of ultrastructural immunocytochemistry has led to new insights into the intracellular processing, storage and secretion of renin. These recent morphological studies are reviewed with the emphasis on the human renin-secreting cell within the kidney.
