(D) Percentage of motile ookinetes after 20-26 hours of incubation between hydrogels compared to parasites directly imaged after setting up the experiment as shown in (B). Shown is the average ± S.D. from at least two independent experiments. (E) Speed of motile ookinetes after 20-26 hours of incubation between hydrogels. Speed on glass was not analyzed (n.a.) due to the low fraction of motile ookinetes at this timepoint.
