Figure 6. Myelin markers expressed in brain of shark embryo.
Section staining for MPZ in hindbrain (A, C) in early stage 32 embryo showed that myelination is starting. In later stage 32 embryos MBP (B, D) showed that a cranial ganglion is undergoing extensive myelination (arrows point to myelinated nerves). Pre-hatching tegmental areas showed myelinated fibers crossing the brain (E, F). MPZ labeled also cell bodies in E.
