Endocardial-Derived Fibroblast (EndD) Validation in Homeostatic Ventricles
(A) Confocal imaging of the EndD marker DKK3 (in red) on cardiac sections from adult Wt1Cre; ZsGreenf/+ mice. ZsGreen labels epicardial derived cells.
(B) Quantification of the percentage of DKK3+ cells co-labelled with the reporter ZsGreen. Data are represented as mean ± SEM. N = 3 biological replicates, 7 technical replicates.
(C) Confocal imaging of DKK3 (in red) on cardiac sections from adult TekCre; ZsGreenf/+ mice. ZsGreen labels endocardial-derived cells.
(D) Quantification of the percentage of DKK3+ cells co-labelled with the reporter ZsGreen. Data are represented as mean ± SEM. N = 3 biological replicates, 7 technical replicates.(E) Enrichr analysis of EndD marker genes identified top related cell (mouse gene atlas) and tissue (ARCHS4 tissues) types.
