Fig. 2

ff1a is expressed in the migrating slow muscle precursor cells. Cross-sections of 24-hpf embryos showing that the migration patterns of (A) ff1a-expressing and (B) F59 positive slow muscle cells are comparable. Dorsal to the top. Somite number counting from the most posterior end is referred to by Roman Numerals and may have 1 somite difference, i.e., Somite I for newly formed 1st and 2nd somites, IV for 3rd to 5th somites, VII for 6th to 8th somites, and so on. In sections of Somite I, the slow muscle precursor cells are located in the adaxial region. These ff1a-expressing cells migrate dorso-ventrally first as shown for Somites IV and VII and then migrate laterally (somites X and XIV). During lateral migration, ff1a transcripts start to be down-regulated (in Somites X and XIV). The pattern of slow muscle heavy chain detected by F59 staining is similar to that of ff1a expression, except that F59 staining remains strong in Somite XIV.
