WebOogenesis as a model system for Delta/Notch signaling Drosophila oogenesis provides an excellent system in which to analyze the Notch signaling pathway for several reasons. First, Delta signals to activate Notch in a large number of follicle cells at the same time, because ∼1000 epithelial follicle cells receive the second signal during stages 5 through 7.
WebOogenesis. The formation of female sex cells from oogonia is called oogenesis. It takes place in the ovary. The primary oocyte divides to form a single ovum. The primary oocyte undergoes meiosis.
