Blood loses it when nerves go bad

Abstract

Myeloproliferative neoplasms are diseases that arise in the stem cells of the blood. In a recent paper published in Nature, Arranz et al. demonstrated that abrogation of sympathetic nerve fibers reduced bone marrow Nestin mesenchymal cells, which in turn led to an expansion of hematopoietic stem cells and progression of myeloproliferative neoplasms.
