Motifs to target specific cardiac cells or cell organelles. a Overview of genes that are higher expressed in subareas of the heart and can be used to target specific cells [73]. The red region indicates atrial cells, the blue region ventricular cells. Genes from cardiac progenitor cells are between brackets, since it is unclear if they are indeed progenitor cell specific. Gene names can differ between species and gene expression may be dependent on developmental stage and specie. *Ly6a is only found in the mouse. b Overview of motifs that can be used to target specific locations within the cell
