| Pattern | The mls-1 transgenes were expressed in the sex myoblast lineage and in a subset of the enteric muscles. Expression of the mls-1 transgenes in the M lineage was detected as early as the sex myoblast granddaughters (M.vl/rpaaa/pa/p). The transgene product was initially observed to accumulate in the uterine muscle progenitors and persisted throughout uterine muscle differentiation. In the initial period after segregation of uterine muscle and vulval muscle fate, the vulval muscle progenitor lineage lacked mls-1 transgene activity. However, after division of the vulval muscle progenitors to Type 1 and Type 2 vulval muscle precursors, mls-1 transgenes were expressed in Type 2 vulval muscles. Expression of mls-1 transgenes was not observed in Type 1 vulval muscles. mls-1 transgenes were also expressed in a subset of the enteric muscles. mls-1 was expressed in the left intestinal muscle (AB.plpppppaa), right intestinal muscle (MS.ppaapp), and the anal depressor muscle (AB.plpppppap). Expression was not detected in the sphincter muscle (AB.prppppap). | |
