Functions for PS Integrins in Tissue Adhesion, Migration, and Shape Changes during Early Embryonic Development in Drosophila

The position-specific (PS) integrins of Drosophila are a family of cell surface heterodimers that function as receptors for extracellular matrix molecules. In this study we used time-lapse videomicroscopy to examine living embryos lacking both maternal and zygotic expression of the genes that encode...
