Abstract
Introduction This study aimed to investigate the effect of muscle-derived stem cell (MDSC) exosomes with overexpressed miR-214 on the regeneration and repair of rat sciatic nerve after crush injury and its molecular mechanism. Methods First, primary MDSCs, Schwann cells (SCs) and dorsal root ganglion (DRG) neurons were isolated and cultured, and the characteristics of MDSCs-derived exosomes were identified by molecular biology and immunohistochemistry. NC mimics and miR-214 mimics were transfected to obtain exo-NC and exo-miR-214. An in vitro co-culture system was established to determine the effect of exo-miR-214 on nerve regeneration. The restoration of sciatic nerve function of rats by exo-miR-214 was evaluated by walking track analysis. Immunofluorescence for NF and S100 was used to detect the regeneration of axon and myelin sheath in injured nerve. The Starbase database was used to analyze the downstream target genes of miR-214. QRT-PCR and dual luciferase reporter assays were used to validate the miR-214 and PTEN interaction relationship. And the expression of the JAK2/STAT3 pathway-related proteins in sciatic nerve tissues were detected by western blot. Results The above experiments showed that MDSCs-derived exosomes with overexpressed miR-214 was found to promote the proliferation and migration of SCs, increase the expression of neurotrophic factors, promote axon extension of DRG neurons and positively affect the recovery of nerve structure and function. In addition, PTEN was a target gene of miR-214. Exo-miR-214 can significantly inhibit the expression level of PTEN, increase the protein expression levels of p-JAK2 and p-STAT3 and the ratio of p-JAK2/JAK2 and p-STAT3/STAT3, also MDSCs-derived exosomes with overexpressed miR-214 can reduce the occurrence of denervated muscle atrophy. Conclusion In summary, the MDSCs-derived exosomes with overexpressed miR-214 is involved in peripheral nerve regeneration and repair in rats after sciatic nerve crush injury to activate the JAK2/ STAT3 pathway by targeting PTEN.

Abstract
Stem cell therapy represents one of the most promising approaches for tissue repair and regeneration. However, the full potential of stem cell therapy remains to be realized. One major challenge is the insufficient homing and retention of stem cells at the desired sites after in vivo delivery. Here, we provide a proof-of-principle demonstration of magnetic targeting and retention of human muscle-derived stem cells (hMDSCs) in vitro through magnetic force-mediated internalization of magnetic iron oxide nanoparticles (MIONs) and the use of a micropatterned magnet. We found that the magnetic force-mediated cellular uptake of MIONs occurs through an endocytic pathway, and the MIONs were exclusively localized in the lysosomes. The intracellular MIONs had no detrimental effect on the proliferation of hMDSCs or their multilineage differentiation, and no MIONs were translocated to other cells in a coculture system. Using hMDSCs and three other cell types including human umbilical vein endothelial cells (HUVECs), human dermal fibroblasts (HDFs), and HeLa cells, we further discovered that the magnetic force-mediated MION uptake increased with MION size and decreased with cell membrane tension. We found that the cellular uptake rate was initially increased with MION concentration in solution and approached saturation. These findings provide important insight and guidance for magnetic targeting of stem cells in therapeutic applications.

Application of adipose-derived, muscle-derived, and co-cultured stem cells for the treatment of stress urinary incontinence in rat models. Low Urin Tract Symptoms 2020; 13:308-318.

Abstract
OBJECTIVES Based on the recent advancements in cell therapy techniques, we aimed to evaluate the efficacy of transurethral injection of autologous adipose-derived stem cells, muscle-derived stem cells, and co-cultured cells for the rehabilitation of stress urinary incontinence rat models. We hypothesized that the utilization of co-cultured stem cells could result in enhanced therapeutic outcomes attributed to their more comprehensive environment of paracrine factors and cytokines. METHODS We performed bilateral pudendal nerve transection surgeries to simulate urinary incontinence in 25 female Wistar rats and employed urodynamic evaluations to confirm the injury. We autologously isolated and cultured adipose-derived mesenchymal stem cells, muscle-derived stem cells, and a mixed culture of the two types, which we subsequently injected into the urethral lumen of the damaged animals. Three weeks after the injection, urodynamic assays, histological staining, and immunohistochemical evaluations were performed to determine the efficacy of the implanted cell cultures in sphincter function improvements or structural modifications. RESULTS Histological evaluations suggested a regenerative process in the muscular layer of the external sphincter 3 weeks after the injection. Also, immunohistochemical analysis revealed a thickened periurethral striated muscle layer in the co-cultured group. Postinjection urodynamic analysis indicated that the urethral pressure profile significantly increased in the co-cultured group compared with other groups. CONCLUSIONS The outcomes of this investigation indicated that the application of co-cultured adipose-derived and muscle-derived stem cells could be associated with higher therapeutic value in stress urinary incontinence patients compared with singular-cell treatments.

Abstract
PURPOSE This study was designed to determine whether the injection of muscle-derived stem cells into the anal sphincter can improve functional properties in a fecal incontinence rat model. METHODS Cryoinjured rats were utilized as a fecal incontinence model. The gastrocnemius muscles of normal three-week-old female Sprague-Dawley rats were used for the purification of the muscle-derived stem cells. The experimental group was divided into three subgroups: normal control; cryoinjured; and muscle-derived stem cells (3 x 10(6) cells) injection group of cryoinjured rats. All groups were subsequently employed in contractility experiments using muscle strips from the anal sphincter, one week after preparation. RESULTS Contractility in the cryoinjured group was significantly lower than in the control after treatment with acetylcholine and KCl. In the muscle-derived stem cells injection group, contraction amplitude was higher than in the cryoinjured group but not significantly (20.5 +/- 21.3 vs. 17.3 +/- 3.4 g per gram tissue, with acetylcholine (10(-4) mol/l); 31 +/- 14.2 vs. 18.4 +/- 7.9 g per gram tissue, with KCl (10(-4) mol/l)). PKH-26-labeled transplanted cells were detected in all of the grafted sphincters. Differentiated muscle masses stained positively for alpha smooth muscle actin and myosin heavy chain at the muscle-derived stem cells injection sites. CONCLUSIONS This is the first study reporting that autologous muscle-derived stem cell grafts may be a tool for improving anal sphincter function.
