Ontogenetic gene expression patterns of mgp (a), bglap (b), SPP1 (c), SPARC (d), and COL1A1 (e). Gene expression measured as the mean expression ratio of the target gene respect to the house-keeping gene (EF1α) at each sample time compared with initial sample time (2 dph). Different letters denote significant differences of the global gene expression (ANOVA, P < 0.05; n = 3).
