The Skinbow

An uncommonly beautiful experiment yields technicolor zebrafish.

Duke scientists programmed individual cells in zebrafish skin to be different colors, a technique similar to a “brainbow,” where individual neurons in the brain are distinguished from one another using fluorescent proteins. This “skinbow” allowed the scientists to visualize how cells respond to injury in zebrafish skin.

Duke has 12,000 tanks full of zebrafish, which lend themselves to study because they reproduce rapidly, we’ve sequenced their full genome, and we can easily manipulate their genes to be favorable to study.
