|A personal message from Dr Mark Hill (May 2020)|
|contributors to the site. The good news is Embryology will remain online and I will continue my association with UNSW Australia. I look forward to updating and including the many exciting new discoveries in Embryology!|

Fibroblast Growth Factor
Fibroblast growth factor 10 (FGF10) expression in mesoderm required for initial lung buds, through FGFR2IIIb transmembrane tyrosine kinase receptor protein.
Fibroblast growth factor 10 (FGF10) and sonic hedgehog (SHH) form a feedback loop for branching
- mesenchyme produced FGF10 signals to the distal epithelium to upregulate SHH expression.
- SHH then feeds back to inhibit Fgf10 expression in the adjacent mesenchyme, dividing in two the Fgf10 expression domain.
- new FGF10 signaling domains serve as two chemoattractant sources, leading to bifurcation of the epithelial tip.
Loop process mediated through FGF-activated transcription factor genes Etv4 and Etv5.

Lipid-containing alveolar interstitial fibroblasts (lipofibroblasts) aid the type 2 alveolar epithelial cells in producing surfactant during neonatal life. A recent study in mouse shows FGF10 is required for this cell population to develop using Fgfr1b and Fgfr2b receptors.
