Fibroblast growth factors (FGFs) play a key role in lung development by mediating complex interactions between epithelial and mesenchymal cells, which are central to processes such as branching morphogenesis, epithelial differentiation, and alveolarization. The findings regarding this interplay highlight the complexity of FGF signaling, as different FGFs contribute to various aspects of lung formation and maturation. Understanding the role of FGF proteins in shaping the lung is crucial for gaining insight into the biology of its development. Furthermore, FGFs orchestrate complex signaling pathways that regulate lung regeneration in adulthood. Therapeutic strategies targeting FGF-dependent pathways appear promising for repairing and improving lung function in diverse pulmonary diseases. In this review, we describe the current perception of the role of FGF proteins in lung development and regeneration, together with an overview of emerging therapeutic strategies aiming at FGF signaling in lung-related disorders.
