There are two conflicting concepts about the cells of the adrenal cortex. One is the escalator or cell-migration theory formulated by Gottschau. According to this theory, the growth of the cortex takes place in the outer part of the cortex and the cells originate from the capsular fibroblasts and gradually migrate inwards towards the medulla until in the zona reticularis they degenerate and are removed. The second is the so-called zonal theory advocated by Deane et al. Deane and Greep firmly believe that the zona glomerulosa and the zona fasciculata of the adrenal cortex are different in structure, origin and function.
In this paper, the author discussed the nature of the cortical cells especially the proliferation of the cortical cells.
