Introduction: The human adrenal gland originates from the adrenogonadal primordium at around 4 weeks post conception (wpc) and undergoes marked developmental changes throughout the first half of pregnancy. Several key aspects of adrenal maturation are well-established, such as the formation of a large inner fetal zone (FZ) and synthesis of dehydroepiandrosterone, but many other processes contributing to adrenal gland development and function in humans are stil...

Introduction: Ovary development was once considered a largely passive process. RNA sequencing (RNAseq) approaches have allowed us to begin to characterise ovary development in previously unparalleled detail, revealing the process to be complex and, still, little understood. A challenge is synthesising and using these data to advance our understanding of clinical disease. Through a clinically-focused lens, we elucidate novel aspects of the transcriptional lands...
