Abstract:
:The aim of the present study was to investigate the presence and localization of the main G protein alpha-subunits in the human fetal adrenal gland during the second trimester of gestation. Immunofluorescence studies conducted on sections from frozen glands obtained immediately after therapeutic abortion indicated that the alpha s subunit of the heterotrimeric Gs protein was detected in all adrenal cell types, except for endothelial cells. The other alpha-subunits had a more specific pattern of distribution. Indeed, the alpha il-2 protein was restricted to the definitive zone, whereas alpha i3 labeling was mainly expressed in the fetal zone. The alpha q protein subunit was localized in vascular endothelial cells at the periphery of the adrenal gland and in fetal cells at the center. Finally, chromaffin cells expressed alpha s, alpha q, and alpha o1, but not alpha o2 nor alpha i. Altogether, these results indicate that the human fetal adrenal gland is not only unique in its particular morphology and expression of steroidogenic enzymes, but also by the differential expression of G protein alpha-subunits. Such cell specific distribution in glands from midgestational fetuses may account for the absence or the different responses to stimuli, when compared with the adult adrenal gland.
