Mom Knows Best: Imprinted Control of Hematopoietic Stem Cell Quiescence

Cell Stem Cell. 2016 Feb 4;18(2):158-60. doi: 10.1016/j.stem.2016.01.004.

Abstract

The mechanisms by which imprinted loci control activity of hematopoietic stem cells (HSCs) are not known. In this issue of Cell Stem Cell, Qian et al. (2016) demonstrate that non-coding RNAs expressed by the maternal-imprinted locus Dlk1-Gtl2 maintain HSC self-renewal through the inhibition of PI3K-mTOR signaling, mitochondrial biogenesis, and metabolic activity.
