Histochemical studies on the developing adrenal gland of the chick (Gallus domesticus).

During the past decade or so, histochemists have paid increasing attention to the study of the adrenal gland. The majority of these studies have been on mammalian adrenals. The more noteworthy among them are those of Allen (1956, 1958), Arvy (1960, 196la), Deane et al., (1946, 1948), Erinko and his coworkers (1952, 1959, 1962, 1962a) Hillarp and Hokfelt (1954, 1955) and Wood (1963). These studies are correlated with the intensive biochemical investigations (reviews by Fieser and Fieser, 1959, Krayer, 1959, and Sourkes, 1962) and the recognition that one portion of the gland, namely the cortex, is essential for vertebrate life.
