Abstract The coordination of pituitary development is complicated and requires input from multiple cellular processes. Recent research has provided insight into key molecular determinants that govern cell fate specification in the pituitary. Moreover, increasing research aimed to identify, characterize, and functionally describe the presumptive pituitary stem cell population has allowed for a better understanding of the processes that govern endocrine cell differentiation in the developing pituitary. The culmination of this research has led to the ability of investigators to recapitulate some of embryonic pituitary development in vitro, the first steps to developing novel regenerative therapies for pituitary diseases. In this current review, we cover the major players in pituitary stem/progenitor cell function and maintenance, and the key molecular determinants of endocrine cell specification. In addition, we discuss the contribution of peripheral hormonal regulation of pituitary gland development, an understudied area of research.

ABSTRACT Removal of the pituitary gland in rats reduces basal lipolysis and greatly diminishes the lipolytic response of isolated fat cells towards L-epinephrine, ACTH and dibutyryl-cyclic-3′5′-AMP (DB-cAMP). Subcutaneous application for 5 days of ACTH, LH, FSH, GH and TSH, single or in combination, does not appreciably influence the responsiveness of fat cells towards lipolytic stimulation. Administration of a hypophyscal homogenate restores the sensitivity of fat cells of hypophysectomized rats. A similar effect is obtained with a combination of growth hormone and corticosterone. In hypophysectomized-adrenalectomized animals only the combination of growth hormone and corticosterone, but not a pituitary homogenate, produces a normal responsiveness of fat cells towards lipolytic stimuli. It is concluded that both the pituitary and adrenal gland are intimately involved in the hormonal regulation of lipolysis in fat cells.
