The Miao Lab investigates the intricate mechanisms governing collective cell movements, with a particular emphasis on delamination—the detachment of cells from their original epithelial layer—and neolamination—the formation of new cell-cell contacts at a distant site. Employing the border cells of the Drosophila ovary as a powerful in vivo model, the laboratory leverages the extensive Drosophila genetic toolkit alongside organ culture methods to perform high-resolution live-cell imaging and optogenetic manipulations. Current studies elucidate how these cells perceive and respond to diverse external cues to orchestrate precise delamination and neolamination. Key molecular players under investigation include gap junction channels, spliceosome components like Cactin, and the channel-independent roles of innexins in regulating microtubules. This research holds significant promise for advancing our understanding of developmental morphogenesis, cancer metastasis—the primary cause of cancer mortality—and applications in tissue engineering and regenerative medicine.
