Introduction: Hormone-producing pituitary cell lineages derive from SOX2+ embryonic precursors. These cells maintain multipotency into early postnatal life, acting as the resident population of pituitary stem cells (PSCs) and contributing extensively to all the endocrine cell lineages. Additionally, paracrine signalling from PSCs is important for cell proliferation of neighbouring progenitors (PMC7803373). It is not known if SOX2+ PSCs are involved in the regulation of additio...

The pituitary gland is a critical endocrine organ regulating multiple essential physiological processes including growth, reproduction, metabolism and the stress response. Hormone-producing pituitary cell lineages are derived from a population of embryonic precursors expressing the transcription factor SOX2. These cells maintain multipotency into early postnatal life, acting as the resident population of pituitary stem cells (PSCs) and contributing to all the endocrine cell li...

Subpopulations of beta cells dictate overall ‘pacing’ of insulin secretion across the islet and therefore the control of glycaemia. Functional beta cell subpopulations also exist in human islets and have an altered subtype distribution in type 2 diabetes. However, the molecular control of the establishment and maintenance of beta cell hierarchy is poorly understood. We hypothesised that the epigenome would govern this heterogeneity. We have identified a novel subpopu...
