Genes are differentially expressed in sporocyst/cercarial pair-wise comparisons (columns and , 'Spo v Cercs') or adult/cercarial pair-wise comparisons (columns and , 'Adults v Cercs'). Genes are highly enriched (three-fold) in sporocysts relative to cercariae (clusters 1-3), in cercariae relative to adults (cluster 3 and 4), and in adults relative to cercariae (clusters 2, 5, and 6).
