Description:
Dermal fibroblasts represent a heterogeneous population of cells with diverse features that remain largely undefined. We reveal the presence of at least two fibroblast lineages in murine dorsal skin. Lineage tracing and transplantation assays demonstrate that a single fibroblast lineage is responsible for the bulk of connective tissue deposition during embryonic development, cutaneous wound healing, radiation fibrosis, and cancer stroma formation. Lineage-specific cell ablation leads to diminished connective tissue deposition in wounds and reduces melanoma growth. Using flow cytometry, we identify CD26/DPP4 as a surface marker that allows isolation of this lineage. Small molecule-based inhibition of CD26/DPP4 enzymatic activity during wound healing results in diminished cutaneous scarring. Identification and isolation of these lineages hold promise for translational medicine aimed at in vivo modulation of fibrogenic behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rinkevich, Yuval -- Walmsley, Graham G -- Hu, Michael S -- Maan, Zeshaan N -- Newman, Aaron M -- Drukker, Micha -- Januszyk, Michael -- Krampitz, Geoffrey W -- Gurtner, Geoffrey C -- Lorenz, H Peter -- Weissman, Irving L -- Longaker, Michael T -- GM07365/GM/NIGMS NIH HHS/ -- R01 GM087609/GM/NIGMS NIH HHS/ -- U01 HL099776/HL/NHLBI NIH HHS/ -- U01 HL099999/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2015 Apr 17;348(6232):aaa2151. doi: 10.1126/science.aaa2151.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Stem Cell Biology and Regenerative Medicine, Departments of Pathology and Developmental Biology, Stanford University School of Medicine, Stanford, CA 94305, USA. ryuval@stanford.edu irv@stanford.edu longaker@stanford.edu. ; Institute for Stem Cell Biology and Regenerative Medicine, Departments of Pathology and Developmental Biology, Stanford University School of Medicine, Stanford, CA 94305, USA.
