Alveologenesis: key cellular players and fibroblast growth factor 10 signaling

Conclusions
A better understanding of the cellular and molecular processes underlying the formation of the secondary septae is critical for the development of new therapies to protect or regenerate the alveoli. This review summarizes briefly the alveologenesis process in mouse and human. Further, it discusses the current knowledge on the epithelial and mesenchymal progenitor cells during early lung development giving rise to the key cellular players (e.g., alveolar epithelial cell type I, alveolar epithelial cell type II, alveolar myofibroblast, lipofibroblast) involved in alveologenesis. This review focusses mainly on the role of fibroblast growth factor 10 (FGF10), one of the most important signaling molecules during lung development, in epithelial and mesenchymal cell lineage formation.
