Dormant hematopoietic stem cells (dHSCs) display superior serial reconstitution capacity compared to active HSCs, although their role in normal hematopoiesis has not been thoroughly investigated. Recently in Cell, Cabezas-Wallscheid et al. (2017) demonstrate involvement of retinoic acid signaling in murine dHSCs for preservation of the HSC pool.

维甲酸使造血干细胞重新进入睡眠状态。

休眠造血干细胞（dHSCs）与活跃的造血干细胞相比，显示出更好的系列重建能力，尽管尚未对它们在正常造血中的作用进行彻底研究。最近在Cell中，Cabbezas-Wallscheid等人。（2017）证明了维甲酸信号参与了小鼠dHSC的保存，以保护HSC库。
