Where this comes from

Abstract

Leptin is an adipocyte-derived hormone involved in energy sensing. In this issue of Cell Stem Cell, Yue et al. (2016) show that leptin is a physiologic signal that acts directly on Leptin-Receptor-expressing mesenchymal stromal cells in adult bone marrow to influence their lineage allocation in vivo, inhibiting bone formation and inducing marrow adipogenesis.
