Lineage tracing using a knockin Pdgfra-rtTA tool indicates distinct contributions of this cell lineage to myofibroblasts in normal development, fibrosis and bronchopulmonary dysplasia models.

Regulation of cellular properties such as ligand secretion and migratory ability through changes in the cytoskeleton mediated by a Wnt5a–Ror2–Vangl2 axis is a major determinant of alveolar formation.

Stromal cell levels and localization of active α₅β₁-integrin are regulated by desmoplastic extracellular matrix control of α_vβ₅-integrin signaling, and predict clinical outcomes for pancreatic and renal cancer patients.

Directed differentiation of stem cells can generate ventral-anterior foregut spheroids that can expand into three-dimensional lung organoids with striking structural, cellular and molecular similarities to the human fetal lung.

RNA profiles from lungs of mice exposed to intermittent hypoxia shared similarity with gene expression changes in human lung from patients with pulmonary diseases, including pulmonary hypertension, COPD, and asthma.

Inhibition of S100a4 represents a novel anti-fibrotic target to improve tendon healing.

Editors' Summary: This Replication Study has reproduced important parts of the original paper.

Comprehensive scRNA-seq analysis of cardiac stromal cells in healthy and injured hearts reveals novel cell types and non-linear cell dynamics, providing new insights into cardiac inflammation, fibrosis and repair.

Macrophage production of MT1-MMP upon MI contributes to adverse cardiac remodeling and worsened function by promoting EndMT via TGFB, suggesting MT1-MMP inhibition as a therapeutic option for patients with MI.

TGFß signaling regulates migration of tenogenic cells from Scx- and non-Scx lineages and is required for functional regeneration after neonatal tendon injury.
