3D-reconstructions based on confocal laser scanning microscopy of specimen stained with antibodies showing the effects of bapx1 upregulation on cranial muscle morphology in Xenopus laevis larvae. Lateral view of the jaw articulation and selected muscles of ZO 17 larvae. a Muscle morphology in a control specimen. b Muscle morphology in a specimen after bapx1 upregulation. The m. levator mandibulae articularis originates more anteriorly on the dorsal surface of the processus muscularis than in control specimens. The m. quadratohyoangularis surrounds the ectopic cartilage without originating from or inserting onto this cartilage. cm, Meckel’s cartilage; ec, ectopic cartilage; lma, M. levator mandibulae articularis; qha, M. quadratohyoangularis
