Abstract
Cover Photograph: Could imaginal discs in insects prove to be an important model for regenerative biology? Authors from Barcelona, Spain, present a summary of current research into imaginal disc regeneration and discuss the power of this tissue as a tool for understanding the genetics of regeneration. See the review “Imaginal discs: Renaissance of a model for regenerative biology” by Cora Bergantiños, Xavier Vilana, Montserrat Corominas and Florenci Serras in this issue (http://dx.doi.org/10.1002/bies.200900105). Images show blastema formation in wing discs that have been cultured for 2 days. Immunostaining reveals mitotic cells (red, stained with anti‐HP3), JNK activation (green, staining of puckered (puc) expression) and the dorsal‐ventral boundary (blue, stained with anti‐Senseless). SPIM (Selective Plane Illumination Microscopy) autofluorescence image of Drosophila was kindly provided by Daniel James White (Max Planck Institute of Molecular Cell Biology and Genetics, Dresden, Germany).
