The Vertebrate Organizer
Springer-Verlag approached me about editing a book about the Spemann Mangold Organizer, to be published as an issue of a series concerning phy siology. I already had some experience as an editor together with Michael Trendelenburg from the special issue, "Developmental Biology in Germany" [Int. J. Dev. Biol. 40(1), 1996]. Primarily, I wondered if it was reasonable to publish another book about the Spemann organizer so shortly after the appearance of the special issue "Spemann-Mangold Organizer [Eds. Eddy De Robertis and Juan Arechaga; Int. J. Dev. Biol. 40(1), 2000]. It could, how ever, be argued that knowledge in this field is growing exponentially and that a lot of new data are available. Since homologous zones of the Spemann-Mangold Organizer have mean while been identified in zebrafish, chicken and mice, we decided that the "Ver tebrate Organizer" would be a better title for the book. I invited many col leagues to participate as contributors. Since the response was very positive, Springer has decided to publish the book as a separate volume.
