• Early evolution of radial glial cells in Bilateria 

      Helm, Conrad; Karl, Anett; Beckers, Patrick; Kaul-Strehlow, Sabrina; Ulbricht, Elke; Kourtesis, Ioannis; Kuhrt, Heidrun; Hausen, Harald; Bartolomaeus, Thomas; Reichenbach, Andreas; Bleidorn, Christoph (Journal article; Peer reviewed, 2017)
      Bilaterians usually possess a central nervous system, composed of neurons and supportive cells called glial cells. Whereas neuronal cells are highly comparable in all these animals, glial cells apparently differ, and in ...
    • Morphological investigations of posttraumatic regeneration in Timarete cf. punctata (Annelida: Cirratulidae) 

      Weidhase, Michael; Helm, Conrad; Bleidorn, Christoph (Journal article; Peer reviewed, 2015-08-06)
      Introduction: Annelids exhibit great regenerative abilities, which are mainly used after injury or during reproduction. These lophotrochozoans thus represent excellent models for regeneration research. However, detailed ...
    • Owenia fusiformis – a basally branching annelid suitable for studying ancestral features of annelid neural development 

      Helm, Conrad; Vöcking, Oliver; Kourtesis, Ioannis; Hausen, Harald (Journal article; Peer reviewed, 2016-06-16)
      Background Comparative investigations on bilaterian neurogenesis shed light on conserved developmental mechanisms across taxa. With respect to annelids, most studies focus on taxa deeply nested within the annelid tree, ...
