Fig. 5. Mitotic and apoptotic trigger wave speeds at different cytoplasmic concentrations follow the generalized Luther’s formula.

a Apoptotic wave speeds at different cytoplasmic concentrations. The solid black curve is the generalized Luther’s formula fitted to the means. Error bars are means ± S.E.M. Data are taken from the same 9 experiments as the ones shown in Fig. 2d. b The value of $A$, calculated as the product of the experimentally determined parameters $k_0$, $D_0$, and $C_1$, is compared to the fitted value (left panel). Likewise, the value of $g$ calculated as the sum of the experimentally determined parameters $g_k$ and $g_D$, is compared to the fitted value (right panel). $k_0$, $D_0$, $g_k$, and $g_D$ are from the exponential fits shown in Fig. 4. Error bars are S.E.M.s calculated directly from the fittings or propagated from the individual experimentally determined parameters. c Apoptotic wave speeds at low cytoplasmic concentrations. Dashed line shows the same fitted curve as in (a), which was obtained from only higher concentration data. Shown are means ± S.E.M. from 3 independent samples. d Mitotic wave speeds at different cytoplasmic concentrations, replotted from Fig. 1g and fitted to the generalized Luther’s formula (black curve). Error bars are means ± S.E.M. Data are from 8 independent experiments. Source data are provided as a Source Data file.
