A, LOX mRNA (tendon); time effect (P= 0.5) and group interaction (P < 0.05). B, MMP-2 mRNA (tendon); time effect (P < 0.05) and group interaction (P= 0.2). C, MMP-9 mRNA (tendon); time effect (P= 0.9) and group interaction (P= 0.7). D, decorin (tendon); time effect (P= 0.5) and group interaction (P= 0.8). E, tenascin-C (tendon); time effect (P= 0.7) and group interaction (P= 0.6). *Time effect, P < 0.05, compared with baseline. $Group effect, P < 0.05, GH vs. Plc. within time point.
