Fast and slow-twitch muscle fibres are correctly specified in jambHU3319 and jamcsa0037 embryos. (A) Superimposed confocal microscopy images of 24 h. p. f. wild-type, jambHU3319, and jamcsa0037 embryos stained with monoclonal antibody F59, which detects slow-muscle-specific myosin heavy chain (sMyHC), show normal slow muscle development in both mutants. (B) Single optical sections of 48 h. p. f. wild-type, jambHU3319, and jamcsa0037 embryos stained with monoclonal antibody EB165, which detects fast-muscle-specific myosin heavy chain (fMyHC), show that the medial mononuclear fibres in both mutants have differentiated as fast-twitch muscle. Myotomes 12–13 shown, anterior left. Scale bars represent 50 μm. |
