The patterns of <i>Foxf1</i> and <i>Foxf2</i> expression during palate development.

<p>(A-D) Whole-mount <i>in situ</i> hybridization detection of <i>Foxf1</i> (A, C) and <i>Foxf2</i> (B, D) mRNAs in the developing palate shelves in E12.5 (A, B) and E13.5 (C, D) mouse embryos. White dashes demarcate the palatal shelf on the right side. Yellow dashes mark the molar tooth germ. (E-H) Immunofluorescent staining of Foxf1 (green) and RFP (red) on sections from the anterior to posterior regions of the palatal shelves in E13.5 <i>Osr2</i>^<i>RFP/+</i> embryos. (I-L) Immunofluorescent staining of Foxf2 (green) and RFP (red) on sections in E13.5 <i>Osr2</i>^<i>RFP/+</i> embryos. p, palatal shelf; t, tongue; l, lower molar; u, upper molar.
