Early Segregation of the Adrenal Cortex and Gonad in Chicken Embryos

This study provides a new basis for understanding how the adrenal gland forms and how steroid hormone‐producing tissues arise during development.

We found that early medial coelomic epithelium (CE) consists of a two‐cell layer‐thick band of epithelial‐like cells, the outer and inner CEs. Lineage tracing experiments suggested that the adrenocortex derives from the inner CE but not from the outer CE, from which the gonad derives. This is the first demonstration of early segregation of adrenocortex and gonad in the CE upon the opening of the coelomic cavity.
