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. WebThe Drosophila egg chamber contains a syncytium of 15 nurse cells and 1 oocyte. These cells are enclosed in an epithelial layer of follicle cells. The nurse cells produce ... timized for egg chamber development from stage 9 or 10 to stage 14.
