![]() aurita from early cleavage up to the planula larva. We described in detail the embryonic development of A. In this article, we report a comprehensive study of the early development of A. aurita using the modern methods of light microscopy, immunocytochemistry, confocal laser microscopy, scanning and transmission electron microscopy. To answer this question, a detailed study of the cellular mechanisms underlying the early development of Aurelia is required. One of the intriguing questions that can be posed is whether the invagination occurring during gastrulation of different cnidarians relies on the same cellular mechanisms. As a reliable representative of the class Scyphozoa, Aurelia can be used for comparative analysis of embryonic development within Cnidaria and between Cnidaria and Bilateria. For Aurelia, the genome was sequenced, the molecular cascades involved in the life cycle transitions were characterized, and embryogenesis was studied on the level of gross morphology. Currently, it is an emerging model of Evo-Devo for studying evolution and molecular regulation of metazoans’ complex life cycle, early development, and cell differentiation. PeerJ 10: e13361 Īurelia aurita (Scyphozoa, Cnidaria) is an emblematic species of the jellyfish.
