This study identifies SOX2+ sustentacular cells as stem cells for postnatal adrenal medulla chromaffin cells, showing their ability to generate both adrenaline and noradrenaline lineages and maintain homeostasis via WNT6 secretion.

The paper shows that glucose metabolism and morphogen signaling interact to establish tonotopic identity in developing hair cells by altering metabolic gradients and morphogen signaling.

The paper shows that pituitary stem cells secrete WNT signals that promote the proliferation of neighboring progenitor cells.
