Analysis of the mechanisms that maintain tissue integrity in seam epithelium

Analysis of the mechanisms that maintain tissue integrity in seam epithelium involves a) generation of strains in which apical-basal polarity, cell adhesion, tissue polarity, and various tumour suppressors can be disrupted specifically in the seam epithelium, and b) analysis of genetic interactions between these regulators, with the goal of causing seam cells to leave the epithelium.
