  Figure 3. A: Double in situ hybridization analysis of X. laevis Ngn1, Ngnr-1, Ngn3 (dark blue) with the mid-hindbrain boundary marker En-2 (red), marked by black arrowheads. Stages are indicated in the lower left corner, embryos are shown in an anterior view. B: Double in situ hybridization analysis of X. laevis Ngn1, Ngnr-1, Ngn3 (dark blue) with the marker for postmitotic neurons N-tubulin (red). The medial (m), intermediate (i) and lateral stripes (l) of N-tubulin expression are indicated in the transversal sections.
