Larval genital discs are sexually dimorphic in many social wasps (Hymenoptera: Vespidae). These sexual traits are visible in vivo and in long-term ethanol-preserved samples. Genital disc morphology provides a cheap, quick, ...

Background: Much of the complex anatomy of a holometabolous insect is built from disc-shaped epithelial structures found inside the larva, i.e., the imaginal discs, which undergo a rapid differentiation during metamorphosis. ...

Imaginal disc growth factor-2 (IDGF-2) is a member of a recently described family of Drosophila melanogaster-soluble polypeptide growth factors that promote cell proliferation in imaginal discs. Although their precise mode ...

Organs mainly attain their size by cell growth and proliferation, but sometimes also grow through recruitment of undifferentiated cells. Here we investigate the participation of cell recruitment in establishing the pattern ...

Wound healing is an essential homeostatic mechanism that maintains the epithelial barrier integrity after tissue damage. Although we know the overall steps in wound healing, many of the underlying molecular mechanisms ...

Many insects, like cockroaches, moths, and flies, can regenerate tissues by extending the growth-competent phases of their life cycle. The molecular and cellular players mediating this coordination between tissue growth ...

Neste estudo foram analisados, histologicamente, o desenvolvimento pós-embrionário das glândulas de veneno e de Dufour, bem como os efeitos da aplicação tópica de hormônio juvenil, sobre a glândula de veneno do híbrido de ...
