Figure 1.

Effect of treating bovine granulosa cells in vitro with FSH (0.33 ng/ml), IGF-I (10 ng/ml) or FSH plus IGF-I on cell number and secretion of oestradiol, progesterone, inhibin-A, activin-A and follistatin. Treatment effects were highly significant (P < 0.0001) in all cases (4 replicates with 6 wells included per treatment per replicate). Bars with no common superscript are different (P < 0.05).
