title: Heat induced developmental uncoupling of mesoderm from ectoderm and endoderm germ layer derivatives during Artemia postembryonic segmentation.
abstract: Taking advantage of the fact than segmentation inArtemia is largely a postembryonic process making it more susceptible to environmental influences, heat treatments ofArtemia newly-hatched nauplii were shown to induce a severe inhibition of mesodermal structures, without apparently affecting the corresponding ectodermal and endodermal derivaives. This inhibition was reversible and with enough time the missing mesodermal structures developed. These results indicate that ectoderm and endoderm development can proceed without neccessarily a concomitant mesodermal differentiation, which in turn can be largely uncoupled from that of the rest of the germ layer derivatives.
