Outline of Final Research Achievements

In this study, optogenetics techniques were introduced into zebrafish pigment cells. When illuminated by blue light, Channelrhodopsin-2 expressing melanophores were artificially depolarized and showed enhanced cellular motility in vitro. Using this technique, we then artificially altered skin pattern in vivo by switching rearing light conditions. The resulting pattern indicated that a reaction-diffusion system is viable in zebrafish skin pattern formation process.
