Comment on “Dynamics of Dpp Signaling and Proliferation Controlâ€
Gerald Schwank; Schu-Fee Yang; Simon Restrepo; Konrad Basler
<jats:p> Wartlick <jats:italic>et al</jats:italic> . (Research Articles, 4 March 2011, p. 1154) reported that growth rates in the <jats:italic>Drosophila</jats:italic> wing disc correlate with increasing Dpp signaling levels, suggesting that the rate of Dpp increase determines the cell-cycle length. Contradicting their model, we found that cells in which the increase of Dpp signaling levels was genetically abrogated grew at rates comparable to those of wild-type cells. </jats:p>

Response to Comment on “Dynamics of Dpp Signaling and Proliferation Controlâ€
Ortrud Wartlick; Peer Mumcu; Frank Jülicher; Marcos Gonzalez-Gaitan
<jats:p> Schwank <jats:italic>et al</jats:italic> . challenge the temporal growth model with an experiment in which Dpp signal transduction is abrogated. They claim that in this condition, cellular Dpp signaling levels do not increase over time but that cells do grow normally. We repeated this experiment and observed an increase of signaling over time. The results are consistent with a temporal model of growth control. </jats:p>
