The paper

X. Wang, et al., “Light-mediated activation reveals a key role for Rac in collective guidance of cell movement in vivo,” Nature Cell Biology, 12:591–98, 2010. 

The finding

When Denise Montell and her team at the Johns Hopkins School of Medicine engineered an actin cytoskeleton-regulating protein to be light sensitive, they discovered it could also control cellular movement in vivo. Read More >
