MMP12 and Paralysis: We further quantified the sciatic nerve functional status and PNI severity using the sciatic functional index and sciatic functional scores. Consistent with the paralysis findings, the indices and scores were significantly higher in the SRC‐1‐/‐ and MMP12 inhibitor groups than in the controls (WT and WT+vehicle groups) (Figure 7E,F), suggesting more optimized preservation of sciatic nerve function and reduced PNI severity.
