مستخلص: | Objective: Mitigation of local pathologic fibrotic tissue deposition is a target area of interest for volumetric muscle loss (VML); nintedanib has shown promise for reduction of fibrosis following VML. Herein studies investigate how in sequence anti-fibrotic treatment administered immediately following VML and delayed rehabilitation could improve functional recovery after VML. Approach: Adult male C57BL/6 mice (n=36) were VML injured or Naïve, and randomly assigned to nintedanib (6 mg/kg/day) for 2 weeks or were left untreated; additionally, mice were given access to a running wheel beginning at 2 weeks until 8 weeks. Terminally, mice underwent maximal in vivo functional testing in addition to quantification of muscle collagen content and fibrotic and myogenic markers. Results: Daily running distances (p=0.17) were similar across groups, but weekly averages were greatest in the VML anti-fibrotic group (p<0.01). As expected, 2 weeks post-VML, all VML-injured mice had lower maximal torque normalized to body and muscle mass than Naïve. By 8 weeks, running alone after VML did not recover function, but mice that received the anti-fibrotic treatment prior to running, had greater torque than those untreated (p<0.01), with functional measurements similar to naïve muscle thar ran, indicating improved functional recovery. Innovation: The ability to translate current FDA-approved pharmaceuticals, in a repurposing approach, is critical to mitigate the pathophysiologic consequences of VML in support of functional recovery. However, foundational and translational studies are still needed to understand feasibility and efficacy. Conclusions: Early prevention of fibrotic tissue deposition supports improvements in muscle quality and force chronically after VML injury. |
