Fig. 7. Tendon cell specification is normal in gyc76C mutant embryos.

In gyc76C²³⁸⁸ heterozygous (A,C) and homozygous (B,D) embryos, tendon cells are specified as indicated by Stripe (Sr) expression (A,A′,B,B′, red, arrows) and differentiate as indicated by HOW expression (C,C′,D,D′, red, arrows). Embryos in A,B were stained for Sr (red) and in C,D for HOW (red) and all embryos were co-stained for β3t to label dorsal muscles and β-gal to distinguish heterozygous from homozygous embryos (not shown). All embryos shown are at stage 16. Scale bar in A represents 5 µm.
