- Vasa unveils a common origin of germ cells and of somatic stem cells from the posterior growth zone in the polychaete Platynereis dumeriliiN Rebscher
Institute of Zoology, Philipps University Marburg, Karl von Frisch Strasse 8, 35032 Marburg, Germany
Dev Biol 306:599-611. 2007..Our data suggest a common origin of germ cells and of somatic stem cells, similar to the situation found in planarians and cnidarians, which may constitute the ancestral mode of germ cell specification in Metazoa...
- The germ plasm component Vasa allows tracing of the interstitial stem cells in the cnidarian Hydractinia echinataNicole Rebscher
Institute of Zoology, University of Marburg, Marburg, Germany
Dev Dyn 237:1736-45. 2008..These results suggest that, in Hydractinia, maternal Vasa protein, but not the mRNA, is a maternal constituent of a germ plasm and might be involved in the specification and maintenance of interstitial stem cells...
- Conserved intron positions in FGFR genes reflect the modular structure of FGFR and reveal stepwise addition of domains to an already complex ancestral FGFRNicole Rebscher
FB 17, Morphology and Evolution of Invertebrates, Philipps Universitaet Marburg, Karl von Frisch Str 8, 35032, Marburg, Germany
Dev Genes Evol 219:455-68. 2009..We propose that the first multidomain FGFR originated in the last common ancestor of Placozoa, Cnidaria, and Bilateria. Additional domains were introduced mainly in the ancestor of triploblasts and in the Ecdysozoa...
