...-vacuolated epithelial-like cells). This cell-fate choice plays an important role in notochord structural integrity, because it determines the formation of vacuoles and the PBM. Furthermore, we found that the Mib-meditated Jagged-Notch signalling is involved in the muscle-patterning activity of the notochord...

... Muscle progenitors Muscle patterning The development of the complex pattern of the larval body wall muscles of Drosophila provides an excellent paradigm of how a final pattern is established through precise genetic control (reviewed by Bate, 1993 ; Baylies et al., 1998 ). Each...

...Charles P. Ordahl; Eli Berdougo; Sara J. Venters; Wilfred F. Denetclaw ABSTRACT The cellular and molecular mechanisms that govern early muscle patterning in vertebrate development are unknown. The earliest skeletal muscle to organize, the primary myotome of the epaxial domain, is a thin sheet...

... to this hypothesis in that we observed that changes in the skull were accompanied by changes within the muscles (i.e., in the absence of the styloid process, the styloid muscles adopt novel points of origin). We observed other muscle patterning defects that are potentially due to a primary neural crest defect...

We conclude that the fate restriction of myoblast pools in early development defines elements of the final adult muscle pattern. The fate restriction of myoblast cells may be a result of genetic...
