Western blot levels and ImageJ analysis of (A) neuregulin 1 Types I and III, (B) ErbB2, and (C) AKT in WT and αBC^−/− animals before injury (N) and at various time points (3, 5, 7, 14, and 28 d) after crush damage (one experiment; n = 4 per group). Displayed are two animals per time point, with each quantification time point consisting of four animals. All data represent mean ± SEM. *P < 0.05 (independent t test).
