Examples

  • Hydra are wonderful experimental animals in that one can ablate stem cells for a particular tissue type, and still get an animal that develops and lives; do the same thing to a vertebrate, for instance knocking out the mesodermal lineage in the embryo, and you get an aborted blob.

    No metazoan is an island - The Panda's Thumb

  • Hox genes are primary regulators of the body plan along the length of the animal; they are expressed in overlapping zones that specify morphological regions of the body, such as cervical, thoracic, lumbar, sacral/pelvic, and caudal mesodermal tissues, where, for instance, a thoracic vertebra would have one kind of shape with associated ribs, while lumbar vertebra would have a different shape and no ribs.

  • Hydra are wonderful experimental animals in that one can ablate stem cells for a particular tissue type, and still get an animal that develops and lives; do the same thing to a vertebrate, for instance knocking out the mesodermal lineage in the embryo, and you get an aborted blob.

    No metazoan is an island - The Panda's Thumb

  • The remaining mesodermal tissue is then consistently shown in the same orange-red ignoring the overlap with the ectodermal derivatives noted above, but only until we get out to the extraembryonic mesoderm, which shows up in yet another, lighter shade of orange.

    Evolution of median fins - The Panda's Thumb

  • Although appearing very different, these movements might be related to the invagination of mesodermal and endodermal anlagen, and ventral condensation and extension of the germ band in the Drosophila embryo.

  • To the right and left of it is a row of mesodermal blocks or somites.

    Hans Spemann - Nobel Lecture

  • It invaginates altogether as if it were still in its old place, builds up part of the axial organs and completes itself out of the mesodermal environment.

    Hans Spemann - Nobel Lecture

  • O. Mangold was able to show that mesodermal organs such as notochord, somites and pronephric ducts could arise from presumptive ectoderm by suitable transplantation at the beginning of gastrulation.

    Hans Spemann - Nobel Lecture

  • Thus in many mammals the mesodermal part of the allantois often appears long before the endodermal part, though this is phylogenetically older.

  • At first he made the mistake of supposing that the body-cavity arose from the segmentation-cavity, but in his later paper he rightly surmised that it was formed from the cavities of the "primitive vertebræ," or mesodermal segments.
