FIGURE 8

Craniofacial morphometric measurements among Wildtype, Fgf9+/–, and Fgf9–/– embryos during palatal elevation. (A) Oral volume, tongue size, tongue height, tongue width, intra-Meckel’s width (distance between the bilateral centers of Meckel’s cartilages), and oral height based on selected serial sections of embryonic heads from three litters. Orange, green, and blue regions indicate the oral volume, tongue size, and head size, respectively. (B) Ratios of craniofacial morphometric parameters. *P < 0.1, **P < 0.05, ***P < 0.001.
