Regulation of Growth during Development: Role of Mechanics — •Lars Hufnagel — EMBL Heidelberg, Heidelberg, Germany

A fundamental and unresolved problem in animal development is the question of how a growing tissue knows when it has achieved its correct final size. A widely held view suggests that this process is controlled by morphogen gradients, which adapt to tissue size and become flatter as tissue grows, leading eventually to growth arrest. I will discuss the spatio-temporal dynamics of that the decapentaplegic (Dpp) morphogen distribution in the developing Drosophila wing imaginal disk and present an alternative model for wing size determination and proliferation control in tissues.
