Re-engineering force-regulating proteins inside cells to control their behavior with specific wavelengths of light. Side view of a small group of optogenetically activated cells forming a furrow toward the inside of the embryo (top image, far left); Side view of a large group of optogenetically activated cells bending toward the outside of the embryo (bottom image, far left); Top view of a large group of optogenetically activated cells bending toward the outside of the embryo (center); Patterns of myosin–a contractile protein–associated with optogenetic activation of a large group of cells (far right).
