Sox Genes Show Spatiotemporal Expression during Murine Tongue and Eyelid Development

Figure 2

Expression of Sox genes in tongue development at E12. Frontal sections showing histology ((a)–(a″)) and in situ hybridization ((b)–(k″)) at the anterior, middle, and posterior regions of mandible in wild-type at E12. Vertical and transverse muscle (vt), genioglossus muscle (gg), superior and inferior longitudinal muscle (sil), geniohyoid muscle (gh), mylohyoid (mm), and hyoglossus muscle (hg). Arrowheads indicate weak expression. Scale bar: 125 μm for (a)–(k″).
