Abstract Sleep deficit and related disorders are becoming increasingly prevalent in modern life and an extensive literature has documented that acute or chronic sleep deprivation can lead to several physiological consequences. Here, we evaluated the effects of sleep deprivation on hematopoietic composition of either bone marrow or peripheral blood. Mice were subjected to paradoxical sleep deprivation (PSD) for 72 h by modified multiple platform method, with or without an additional sleep recovery (SR) period of 10 days. PSD decreased total cellularity of the bone marrow and peripheral blood concomitantly. Subsequent analysis of cell composition showed that absolute number of hematopoietic stem/progenitor cells and colony-forming units was decreased. Moreover, the absolute number of granulocytes and monocytes in bone marrow was reduced in PSD group. These alterations were paralleled by an accumulation of neutrophils and monocytes in peripheral blood. PSD also induced lymphopenia in the circulation. To the best of our knowledge, this is the first study that demonstrates the importance of sleep on the hematopoietic microenvironment and provides new insights into the relationship between sleep and the immune system.
