Fig 2D. Whole-mount in situ analysis of MEL1 in Xenopus. (1, 2) Lateral views of early tailbud stage embryos. Note MEL1 expression in cranial crest cells, in the head mesenchyme and in the otic vesicle. (3, 5) High magnification view of the head and transversal sections of early tadpoles. Note that MEL1 staining is now also apparent in various parts of the brain and in the retinal pigment epithelium. (6) Lateral view and horizontal sections of late tadpoles. Note that additional MEL1 staining is seen in the heart and in the pronephric distal tubule and duct.
