Autoactivation and autoinhibition can close a feedback loop of body size control. Here, an error in the published parameter values is found and corrected. Introduction Insect larvae grow until an appropriate body size is reached for molting or metamorphosis.

How does morphogen transport in a growing tissue feed back on tissue growth through morphogen signaling and cell division? Introduction The Drosophila wing primordium is a two-dimensional epithelial tissue that grows in response to the concentration profile of the morphogen Dpp (see Fig.

Autoregulatory multicellular incoherent feedforward loop (mIFFL) that generates the 7-stripe even-skipped (eve) expression pattern in Drosophila melanogaster embryogenesis Introduction This model demonstrates the influence of maternal effect genes and gap genes on the even-skipped (eve) gene.

Organs mainly attain their size by cell growth and proliferation, but sometimes also grow through recruitment of undifferentiated …
