Use of the TetON System to Study Molecular Mechanisms of Zebrafish Regeneration

Overview

This article outlines the workflow for using the TetON system to achieve tissue-specific gene expression in the adult regenerating zebrafish tail fin. The procedure involves generating transgenic lines and inducing gene expression through doxycycline administration.
