Developmental and adult tissue expression profiles of differentially expressed genes in the three cardiac chambers.

<p>The heat maps represent spatiotemporal expression profile of 96 chamber-restricted genes across 11 zebrafish developmental stages and 6 adult tissue types. The colour key represents transcripts in the range of 0 for genes with least expression to 10 for transcripts with maximum expression. Genes marked with asterisks (*) represent those mentioned in the text (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0147823#sec012" target="_blank">Results</a> & <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0147823#sec023" target="_blank">Discussion</a>).
