RT-qPCR analysis of mRNA coding for StAR, P450scc, P45017α, 3β-HSD and 17β-HSD on chick embryonic days 8 (n = 10), 10 (n = 17), 12 (n = 14), 14 (n = 10), 16 (n = 14), and 18 (n = 12). Data are reported as relative mRNA expression and represent mean normalized mRNA transcript number in copies/µL±SEM. 3β-HSD increased (F_{5, 68} = 89.282, p<0.0001) and 17β-HSD decreased (F_{5, 68} = 16.027, p<0.0001) significantly between embryonic day 8 and day 18.
