Sox Genes Show Spatiotemporal Expression during Murine Tongue and Eyelid Development

Figure 5

Expression of Sox genes in tongue development at E18. Frontal sections showing histology ((a)–(a″)) and in situ hybridization ((b)–(i″)) at the anterior, middle, and posterior regions of mandible in wild-type at E18. Arrowheads indicate weak expression. Scale bar: 700 μm for (a)–(i″).
