Cell-to-Cell Interactions during Early Drosophila Oogenesis: An Ultrastructural Analysis.

Abstract excerpt

Drosophila oogenesis requires the subsequent growth of distinct egg chambers each containing a group of sixteen germline cells surrounded by a simple epithelium of follicle cells. The oocyte occupies a posterior position within the germ cells, thus giving a distinct asymmetry to the egg chamber. Although this disposition is critical for the formation of the anterior-posterior axis of the embryo, the interplay...
