FIG. 3.

Comparison of functional recovery observed after application of various keratin hydrogel formulations to TA VML injury at 4 and 8 weeks postimplantation. Peak isometric torque measured at (A) 4 weeks and (B) 8 weeks. There was no statistically significant functional benefit to the inclusion of cells in the various injected KN hydrogel treatments. In all cases, individual responses are presented as a ratio of the respective group mean of the initial maximum preinjury isometric torque response (presented in Fig. 2) as well as their body weight. Data are presented as mean ± SEM. *Significantly different at the p < 0.05 level using Fisher's PLSD post hoc test; after performing a two-way ANOVA for matched samples. Group sample sizes are listed in parentheses. KN, keratin. PLSD, protected least significant difference. Color images available online at www.liebertpub.com/tea
