Outline of Final Research Achievements

To explore the potential role in pattern formation processes as one of the possible cell-cell communication protocols, the shifts of cellular membrane potential were examined. We generated transgenic zebrafish expressing voltage-sensitive fluorescent probes in pigment cells. We also developed an individual tracking and irradiation system that can optically and separately stimulate the left and right side of the body, which enables the analysis of the effects of membrane potential on the pigment pattern formation.
