Gli-fully Halting the Progression of Fibrosis

Abstract

Activating triggers, selective markers, and the residual regenerative potential of scar-forming myofibroblasts are largely determined by their origin. In this issue of Cell Stem Cell, Schneider et al. report that bone marrow myofibroblasts derive from Gli1⁺ mesenchymal stromal cells and that a Gli inhibitor targets them for elimination in mice and humans, ameliorating fibrosis.
