Fig. S4. Xenopus lungs lack the branching program and Sox9 expression, and initiates alveolar differentiation immediately after lung specification. Whole mount in situ hybridization of Xenopus embryos at indicated stages (St). The lungs are indicated with dashed lines if stained or arrowheads if unstained. Open arrowheads indicate Sox9 expression in the pharyngeal arches. The onset of Sftpb expression is slightly later than that of Sftpc expression (Fig. 1C). (Scale bar, 200 μm.)
