Summary

The aim of the approach was to use RNAseq analysis to identify genes expressed in Xenopus epicardium that were affected by embryonic depletion of the epicardial transcription factor Tcf21 compared to control-MO injected siblings. Both upregulated and downregulated genes were validated by RT-PCR and whole embryo in situ hybridization to validate gene expression and assess spatio-temporal distribution of genes of interest within the heart and epicardium. Approximately 70-100 stage 44-46 Xenopus laevis hearts were dissected to isolate total mRNA from which poly-adenylated RNA was extracted using the Illumina standard protocol. This experiment represents one replicate from pooled hearts.
