P{twi-CD2} has been used to examine the development of the embryonic mesoderm after gastrulation and to locate the progenitor cell populations for different mesodermal derivatives. Results demonstrate that the metamerically repeated anterior-posterior subdivision of the mesoderm is an essential element in laying out the pattern of mesodermal progenitor cells and in distinguishing between an internal cell layer which will give rise to the visceral muscle progenitors and an external layer which will generate the somatic muscles and the heart.
