The adrenal gland controls a plethora of crucial physiological functions, and dysfunction is associated with severe morbidity. Because of the vital importance of appropriate adrenal function, the development and function of the gland have been intensively studied, and these investigations have revealed fascinating developmental origins and a remarkable remodeling and regenerative capacity in the adult. This chapter, focusing on the adrenal cortex, will describe our current understanding of the development and maintenance of the adrenal gland, which has been advanced over recent years by the use of sophisticated genetic models in the study of both normal function and disease. This work has shed light on the transcriptional networks and signaling pathways involved in development and maintenance of the gland and in its pathology; these are discussed in the light of the wealth of physiological information gathered in studies of human and rodent adrenal development and function.
