In the Berg Lab, we use the fruit fly Drosophila melanogaster to investigate cell communication and cell migration, two processes critical for development and human disease progression. We study the signaling pathways that pattern the follicular epithelium surrounding the oocyte. We also investigate the link between these cell fates and the subsequent cell shape changes and movements that reorganize the flat epithelium into two closed tubes. Patterning and morphogenesis are the fundamental building blocks of all developmental processes. Learn more about these processes and the scientists who study them by exploring our site.
