In the multiheaded strain (mh‐1) of Hydra magnipapillata the ectodermal epithelial cells are responsible for the formation of additional heads and the endodermal epithelial cells for the reduced ability to regenerate a foot by Zeretzke, Stefanie, Berking, Stefan

“…Hydra consist of three self‐renewing cell lineages: the ectodermal epithelial, endodermal epithelial and interstitial cell lineages. The role of these cell…”

Principles of branch formation and branch patterning in Hydrozoa by Berking, Stefan

“…The freshwater polyp Hydra produces buds which separate from the parent. Other Hydrozoa produce branches which remain connected to the parent, thus forming a…”

A model for budding in hydra: pattern formation in concentric rings by Berking, Stefan

“…Current models of pattern formation in Hydra propose head-and foot-specific morphogens to control the development of the body ends and along the body length…”

Commitment of stem cells to nerve cells and migration of nerve cell precursors in preparatory bud development in Hydra by Berking, Stefan

“…Budding in Hydra starts as an evagination of the double-layered tissue in the parent animal's gastric region. Five hours later the density of nerve cells in…”

Compartments in Scyphozoa by Berking, Stefan, Herrmann, Klaus

“…Polyps of Scyphozoa have a cup-shaped body. At one end is the mouth opening surrounded by tentacles, at the other end is an attachment disc. The body wall…”

A newly discovered oxidant defence system and its involvement in the development of Aurelia aurita (Scyphozoa, Cnidaria): reactive oxygen species and elemental iodine control medusa formation by Berking, Stefan, Czech, Nicole, Gerharz, Melanie, Herrmann, Klaus, Hoffmann, Uwe, Raifer, Hartmann, Sekul, Guy, Siefker, Barbara, Sommerei, Andrea, Vedder, Fritz

“…In Aurelia aurita, applied iodine induces medusa formation (strobilation). This process also occurs when the temperature is lowered. This was found to increase…”

A shoot meristem-like organ in animals; monopodial and sympodial growth in Hydrozoa by Berking, Stefan, Hesse, Marco, Herrmann, Klaus

“…Thecate Hydrozoa produce stems from which polyps branch off. Similar to plants these stems form in two ways, either in a sympodial or in a monopodial type of…”

Sterile polystyrene culture dishes induce transformation of polyps into medusae in Aurelia aurita (Scyphozoa, Cnidaria) by Herrmann, Klaus, Siefker, Barbara, Berking, Stefan

“…Polyps of Aurelia aurita produce medusae once a year. Under laboratory conditions this process, termed strobilation, can be induced by lowering the incubation…”

Ca2+-ions and pattern control in Hydra by Zeretzke, Stefanie, Pérez, Fernando, Velden, Kirsten, Berking, Stefan

“…The fresh water polyp Hydraforms buds which develop a foot at their base and separate from the parent. In the strain H. vulgaris (Zürich), various compounds…”

Shaping of Colony Elements in Laomedea flexuosa Hinks (Hydrozoa, Thecaphora) Includes a Temporal and Spatial Control of Skeleton Hardening by Kossevitch, Igor A., Herrmann, Klaus, Berking, Stefan

“…The colonies of thecate hydroids are covered with a chitinous tubelike outer skeleton, the perisarc. The perisarc shows a species-specific pattern of annuli,…”
