Fgf7 is expressed in the septal mesenchyme during nasal gland development. (A) At E14.5 Fgf7 expression is not associated with the elongating Steno's duct. (B) When the Steno's gland is branching at E15.5 no Fgf7 is observed near the branching gland. Fgf7 expression is still maintained in the mesenchyme surrounding the NLD (B – inset image). (C) Fgf7 expression is not found associated with the elongate LNG2 and 3 ducts or (D) the budding LNG5 at E15.5. (E) Fgf7 expression is not associated with the epithelium where the MSG will bud at E14.5 or (F) surrounding the branching MSG at E15.5. (G) At E14.5, a section through the nasal septum shows Fgf7 expression throughout the mesenchyme. (H) At E15.5, Fgf7 expression is seen in the anterior mesenchyme of the nasal septum close to the elongating MNG ducts. A–F scale bar=100 µm, G-H scale bar=200 µm.
