Fig. 2From: Understanding alveolarization to induce lung regenerationMesenchymal cell-types during alveolarization. Alveolar mesenchymal fibroblasts such as myofibroblasts and lipofibroblasts differentiate from mesenchymal progenitor cells. Key cell lineages involved are the platelet-derived growth factor receptor (PDGFR)α lineage, the fibroblast growth factor (FGF)10 lineage and the GLI-Kruppel family member (Gli-1) lineage. Elastin deposition by myofibroblasts takes place at the so called “secondary crests” visualized in 2D lung sectionsBack to article page
