The role of the forkhead transcription factor, Foxc1, in the development of the mouse lacrimal gland

D Mattiske, P Sommer, SH Kidson, BLM Hogan



The lacrimal gland produces secretions that lubricate and protect the cornea of the eye. Foxc1 encodes a forkhead/winged helix transcription factor required for the development of many embryonic organs. Autosomal dominant mutations in human FOXC1 cause eye disorders such as Axenfeld-Rieger Syndrome and glaucoma iris hypoplasia, resulting from malformation of the anterior segment of the eye. We show here that lacrimal gland development is severely impaired in homozygous null Foxc1 mouse mutants, with reduced outgrowth and branching. Foxc1 is expressed in both the epithelium of the lacrimal gland and the surrounding mesenchyme. FGF10 stimulates the growth and branching morphogenesis in culture..
