Category: Basic Sciences/Biologics Introduction/Purpose: Skeletal muscle fibrosis induced by the increase of collagen occurs after limb lengthening which is also called distraction osteogenesis. Although there are studies about influence of platelet rich plasma (PRP) on tissues healing process, its effectiveness is still controversial. The aim of this study was to examine whether PRP decreased the skeletal muscle fibrosis induced by limb lengthening. Methods: Tibial osteotomy was done to 8-week-old wild type mice. Tibia was lengthened at a rate of 0.42 mm/day during 2 weeks, launching 1 week after tibial osteotomy. Just after lengthening completed (3 weeks after tibial osteotomy), PRP was injected into the gastrocnemius muscle (PRP group). As a sham group, phosphate buffered saline (PBS) was injected into the gastrocnemius muscle (non-PRP group). The gastrocnemius (GC) muscles were taken and analyzed at 4, 6, 8 and 10 weeks after tibial osteotomy. Results: The fibrotic area of the GC muscles in the both groups increased at 4 weeks after tibial osteotomy in histological analysis (Figure). Then, it gradually decreased at 6, 8, and 10 weeks after tibial osteotomy. There were no significant differences between the both groups at 6, 8, and 10 weeks after tibial osteotomy. Hydroxyproline, which was a major constituent of collagen, increased in the non-PRP and PRP groups by limb lengthening as well. However, significant changes were not found between the both groups at all any points. Conclusion: At first, we anticipated that PRP should reduce the skeletal muscle fibrosis after limb lengthening significantly. But our results implied that PRP did not decrease the skeletal muscle fibrosis induced by limb lengthening.

Extracellular matrix (ECM) components play an important role in maintaining skeletal muscle function, but excessive accumulation of ECM components interferes with skeletal muscle regeneration after injury, eventually inducing fibrosis. Increased oxidative stress level caused by dystrophin deficiency is a key factor in fibrosis in Duchenne muscular dystrophy (DMD) patients. Mesenchymal stem cells (MSCs) are considered a promising therapeutic agent for various diseases involving fibrosis. In particular, the paracrine factors secreted by MSCs play an important role in the therapeutic effects of MSCs. In this study, we investigated the effects of MSCs on skeletal muscle fibrosis. In 2–5-month-old mdx mice intravenously injected with 1 × 105 Wharton’s jelly (WJ)-derived MSCs (WJ-MSCs), fibrosis intensity and accumulation of calcium/necrotic fibers were significantly decreased. To elucidate the mechanism of this effect, we verified the effect of WJ-MSCs in a hydrogen peroxide-induced fibrosis myotubes model. In addition, we demonstrated that matrix metalloproteinase-1 (MMP-1), a paracrine factor, is critical for this anti-fibrotic effect of WJ-MSCs. These findings demonstrate that WJ-MSCs exert anti-fibrotic effects against skeletal muscle fibrosis, primarily via MMP-1, indicating a novel target for the treatment of muscle diseases, such as DMD.

Complementary therapies, such as acupuncture and massage, had been previously reported to have therapeutic effects on skeletal muscle contusions. However, the recovery mechanisms on skeletal muscles after blunt trauma via the combination of electroacupuncture (EA) and massage therapy remain unclear. In the present study, a rat model of the skeletal muscle fibrosis following blunt trauma to rat skeletal muscle was established, and the potential molecular mechanisms of EA + massage therapy on the skeletal muscle fibrosis were investigated. The results suggested that EA + massage therapy could significantly decrease inflammatory cells infiltration and collagenous fiber content and ameliorate the disarrangement of sarcomeres within myofibrils compared to the model group. Further analysis revealed that EA + massage therapy could reduce the degree of fibrosis and increase the degree of myofibroblast apoptosis by downregulating the mRNA and protein expression of transforming growth factor- (TGF-) β1 and connective tissue growth factor (CTGF). Furthermore, the fibrosis of injured skeletal muscle was inhibited after treatment through the normalization of balance between matrix metalloproteinase- (MMP-) 1 and tissue inhibitor of matrix metalloproteinase (TIMP). These findings suggested that the combination of electroacupuncture and massage therapy could alleviate the fibrotic process by regulating TGF β1-CTGF-induced myofibroblast transdifferentiation and MMP-1/TIMP-1 balance for extracellular matrix production.
