This shell less model, makes it possible to graft dissociated cells or fragments of tissues without risk of immune rejection. The implants, revascularized by the egg, find a complex environment (ex vivo ...

Cnidarians are diploblastic, have organized tissue
... All cnidarians show the presence of two membrane layers in the body that are derived from the endoderm and ectodermof the embryo. The outer layer (from ectoderm) is called the epidermis and lines the outside of the animal, whereas the inner layer (from endoderm) is called the gastrodermis and lines ...
