How do animals produce a healthy egg cell? To answer this, many developmental biologists investigate the complex choreography of factors required for successful egg cell development, called oogenesis. This process is crucial to the survival and reproduction of many vertebrate and invertebrate species and, remarkably, diverse species often employ a common strategy where the growth of the egg cell is supported by an interconnected network of germline, or reproductive, cells. Like cellular factories, the job of the germline cells is to produce and export nutrients to the egg via connecting cytoplasmic canals. The nutrients these support cells supply to the egg include proteins and the nucleic acids that code for them, called RNA transcripts.
