Formation of striated abdominal body muscles Z-projection of a multi-photon movie showing developing dorsal abdominal muscles expressing Mhc-GFP. Note the simultaneous establishment of the periodic Mhc-GFP pattern that aligns at about 52h APF across the entire muscle. Round moving cells are hemocytes digesting larval Mhc-GFP. Movie plays with 5 frames per second. Time is indicated in hh:mm APF.
