Movie 1

TEAZ can be used to introduce transgenes in the adult heart. Casper fish were injected into the heart through the gills with 1 μl of 1000ng/μl of a plasmid carrying the myl7:GFP transgene (along with a ubb:Cre cassette that is unrelated for the purposes of this study) (n=2/4). Video of the beating fluorescent heart was taken in the GFP channel.
