Melatonin, circadian metabolism, mitochondrial remodeling, and cell size dynamics in primitive hematopoietic stem cells.
Primitive hematopoietic stem cells (pHSCs) sustain lifelong hematopoiesis through tightly regulated transitions between quiescence and activation. Circadian oscillations influence hematopoiesis; however, the mechanisms coordinating metabolic state and stem cell function daily remain incompletely defined. Here, we show...
