Pituitary stem cells (PSCs) expressing SOX2 persist throughout life, giving rise to all pituitary endocrine lineages. These cells are highly active at early postnatal stages but this potential declines with age, rendering them mostly inactive in adulthood. The LATS/YAP/TAZ signaling cascade can influence stem cell fate and activity in multiple tissues and we previously identified activity of this axis in the developing and postnatal pituitary. Using a series of genetic manipul...

A tightly regulated stress system is pivotal for health and the adrenal cortex is a master regulator of the endocrine stress response. The adrenal cortex is characterized by constant cell renewal in part mediated by differentiation and lineage conversion of undifferentiated cell types. To date, the contribution of stem cells to organ plasticity during stress has been implicated but is not fully understood. Recently, we were able to show that a prolonged stress exposure leads t...

The anterior pituitary gland is a critical endocrine organ responsible for many important physiological processes including puberty, fertility, metabolism and the stress response. It is derived from, and maintained by, a population of SOX2+ progenitor/stem cells which become more quiescent with age until their direct contribution to tissue turnover becomes negligible. Previous research has demonstrated that the postnatal SOX2+ population exhibits heterogeneity in terms of mark...

Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumours, which arise from neural crest (NC)-derived structures: the adrenal medulla and the paraganglia. Around one third of PPGLs are associated with inherited cancer susceptibility genes, the highest rate among all tumour types. Currently, the only diagnostic criterion for malignant disease is the presence of metastasis and no molecular or histological features have been identified that help predict risk. A...
