Background: Using genetic lineage tracing in the mouse pituitary, we previously revealed that SOX2 positive cells can act as stem cells in vivo and contribute to all hormone-secreting cell types during postnatal life. However, SOX2-expressing stem cells are not the sole source of new endocrine cells, instead they complement contribution from more committed cell types during organ homeostasis.Objective and hypotheses: We seek to determine key sig...
