A, IGF-1Ea mRNA (tendon); time effect (P < 0.05) and group interaction (P < 0.05). B, COL1A1 mRNA (tendon); time effect (P= 0.07) and group interaction (P < 0.05). C, COL3A1 (tendon); time effect (P= 0.1) and group interaction, (P < 0.05). *Time effect, P < 0.05, compared with baseline (GH). $Group effect, P < 0.05, GH vs. Plc within time point. Data are geometric means ± SEM.
