WebDrosophila egg chamber development depends on a number of dynamic cellular processes that contribute to the final shape and function of the egg. We can gain insight into the mechanisms underlying these events by combining the power of Drosophila genetics and ex vivo live imaging. WebDuring stages 9 and 10, the egg chamber continues to elongate because of oscillating, myosin-mediated contraction, and the oocyte grows dramatically because of the uptake of yolk proteins (i.e., vitellogenin, Vg). After stage 10, growth stops, and the active phase of egg chamber elongation is complete.
