FIGURE 7:
Amphiphysin and dynamin differentially regulate cleavage furrow ingression. (A) Representative kymographs of ingressing furrows in control and amphiphysin-null Drosophila lines. (B) Quantitation of the velocity of the different stages of furrow ingression during cellularization of embryos in A. Data were compiled from at least five embryos for each condition. (C) A representative kymograph of ingressing furrows in the shibirets Drosophila line at the nonpermissive temperature of 32°C. (D) Quantitation of the velocity of the different stages of furrow ingression during cellularization of embryos in C. Error bars, ±SD. Data were compiled from five embryos for each condition. Bar, 5 μm.
