Comparison of the expression profiles of kdrl:mCherry-positive cells in injured versus uninjured zebrafish cardiac ventricle and analysis of the expression prolife of postnb:citrin-positive cells upon injury compared to the rest of cardiac cells.. Danio rerio

Contrary to mammals, zebrafish regenerate their heart upon cryoinjury of the cardiac ventricular apex. Regeneration is preceed by a fibrotic response. To understand the contribution of different cell sources to zebrafish cardiac fibrosis we performed an RNASeq including endocardial kdrl:mCherry cells from an uninjured heart, and activated endocardial kdrl:mCherry cells, postnb:citrine fibroblasts and the rest of the cells at 7 days post injury. Overall design: Three to six biological replicates consisting of different cell types obtained from the ventricular apex.
