- SCPP cluster genes associated with enamel formation are barely expressed in the RNA-seq dataset. Abbreviations: N/A not annotated, NE not expressed, NRC normalised read count; ?: suggestive expression based on genomic clustering in zebrafish. Table separates human SCPP ‘bone/dentin’ genomic cluster, SCPP ‘enamel’ genomic cluster, and human ‘ancestral’ SCPP genes. Green numbering represents passing arbitrary Log2 fold change thresholds. Mean NRC is mean read count taken from the three ontogenetic and regenerating samples. AMELX and AMELY have been omitted from analysis as zebrafish do not have sex chromosomes
