Rate of Progression through a Continuum of Transit-Amplifying Progenitor Cell States Regulates Blood Cell Production

？ Transcriptomic continuums correlate with phenotypic continuums in erythropoiesis ？ Degree of developmental progression per cell cycle governs proliferative capacity ？ Glucocorticoids uncouple cell division and differentiation speed in erythropoiesis ？ Erythroid progenitor cell divisions are symmetri
