Research Abstract

Bloods are born in the bone. Here, we present the severe impairment of granulocyte-colony stimulating factor(G-CSF)-induced hematopoietic stem cell(HSC) mobilization in vitamin D receptor(VDR) deficient mice. VDR is essential for durableβ2-adrenergic receptor signaling in stem cell niche. Our study demonstrates not only a novel function of VDR as a critical modulator of HSC trafficking, but also the presence of a sympathetic nervous system-mediated bone remodeling mechanism through VDR. VDR plays a pivotal role in the regulation of hematopoietic stem cell niche.
