Morphological correlates of hormone secretion in the rat adrenal cortex and the role of filopodia.


Rat adrenals in different states of stimulation were examined by transmission electron microscopy following perfusion fixation using an in situ isolated-circulation technique. In unstimulated glands, intracortical capillaries were constricted and the cells of the cortex were pressed closely together with little development of filopodia or intercellular… (More)
