Mechanistic Studies of the Regulation of Cardiomyocytes Spatial Distributions by Heterogeneous Erbb2 Expression [scRNA-Seq]

Purpose: To explore the endogenous expression pattern of Erbb2. Methods: Approximately 1000 hearts dissected from 72 hpf Tg(myl7:mCherry) embryos were digested in 0.25% trypsin-EDTA solution for single-cell RNA sequencing. Results: We found that ventricular Erbb2 expression was highly enriched in subcluster 0 and 2, but weakly expressed in subcluster 3, 10 and 12. Conclusions: Erbb2 exhibits heterogeneous expression during trabeculation. Overall design: 72 hpf Tg(myl7:mCherry) zebrafish hearts were collected for single-cell RNA sequencing.
