Abstract

The study aimed to analyze the dynamics of the development of cortical and medullary cells of adrenal gland in the long-tailed macaque (Macaca fascicularis) during pre- and postnatal period. The samples of adrenal glands were taken from 5 fetuses aged 70, 85, 100, 120, and 150 days of gestation, a newborn aged 10, and an infant aged 105 days old. The samples of the adrenal glands were stained with hematoxylin-eosin and Masson trichrome (Goldner?s modification). The results showed that the fetal adrenal cortex consisted of a definitive and fetal zones, but in the late gestation (fetus aged 150 days of gestation), the transitional zone appeared between both zones. At the postnatal period, the definitive zone changed to glomerulosa zone, while the outer cells of the transitional zone changed to fasciculata zone which radially arranged. The results indicated that the fetal zone was present until birth and it will disappear gradually after birth. The medullary cells were found at the fetal stages as an irregular structure of small islands of chromaffin cells in the fetal zone. This structure migrated slowly to the center of the adrenal glands. The characteristics of mature chromaffin cells were found in the adrenal glands at postnatal period. In conclusion, the cortex adrenal of the newborn of long-tailed macaque consisted of zona glomerulosa, zona fasciculata, zona transitional, and the remaining fetal zone that has dissapeared gradually after birth.

Abstract

The objective of this study is to observe the relationship of development of adrenocorticotropic hormone (ACTH) cells of adenohypophysis?adrenal cortex axis during pre and postnatal period of longtailed monkey (Macaca fascicularis). Five fetuses aged 70, 85, 100, 120, and 150 days of gestation and 2new born aged 10 and 105 days old were used as research materials. The sections of the pituitary gland stained immunohistochemically using human ACTH antiserum and the adrenal glands stained by Hematoxylin-Eosin procedures. At the fetus 120 days old, the ACTH cells and blood vessel of fetaladenohypophysis developed well and its similar that found in older age. This condition suggested distributing the ACTH to whole body optimally. At the same time, the adrenal cortex cells of fetus 120 days old were active in proliferation and differentiation processes to form transition zone that lies between definitive and fetal zones, and central vein also developed in adrenal gland. In fetus aged 150 days, the cortex adrenal structure was similar with found in older fetus. The adenohypophysis ACTH cells developed earlier than adrenal cortex and their secretion suggested influencing the development of adrenal cortex cells of long-tailed monkey.
