Abstract
OBJECTIVE The aim of the present study was to evaluate the effects of myoblast inoculation in combination with photobiomodulation therapy (PBMT) on skeletal muscle tissue following injury. MATERIALS AND METHODS Sixty-five Wistar rats were divided into five groups: Control-animals not submitted to any procedure; Injury-cryoinjury of the tibialis anterior muscle; HBSS-animals submitted to cryoinjury and intramuscular Hank's Balanced Salt Solution; Injury + Cells-animals submitted to cryoinjury, followed by myogenic precursor cells (C2C12) transplantation; Injury + Cells + LLLT-animals submitted to cryoinjury, followed by myogenic precursor cells (C2C12) transplantation and PBMT (780 nm, 40 mW, 3.2 J in 8 points). The periods analyzed were 1, 3, and 7 days. The tibialis anterior muscle was harvest for histological analysis, collagen analysis, and immunolabeling of macrophages. RESULTS No differences were found between the HBSS group and injury group. The Injury + Cells group exhibited an increase of inflammatory cells and immature fibers as well as a decrease in the number of macrophages on Day 1. The Injury + Cells + LLLT group exhibited a decrease in myonecrosis and inflammatory infiltrate at 7 days, but an increase in inflammatory infiltrate at 1 and 3 days as well as an increase in blood vessels at 3 and 7 days, an increase in macrophages at 3 days and better collagen organization at 7 days. CONCLUSION Cell transplantation combined with PBMT led to an increase in the number of blood vessels, a reduction in myonecrosis and total inflammatory cells as well as better organization of collagen fibers during the skeletal muscle repair process.

Treatment of experimental esophagogastric myotomy with bone marrow mesenchymal stem cells in a rat model. Neurogastroenterol Motil 2013; 25:e669-79. [PMID: 23859028 DOI: 10.1111/nmo.12182] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2013] [Accepted: 06/16/2013] [Indexed: 12/17/2022]
Abstract
BACKGROUND Over the last 15 years, many studies demonstrated the myogenic regenerative potential of bone marrow mesenchymal stem cells (BM-MSC), making them an attractive tool for the regeneration of damaged tissues. In this study, we have developed an animal model of esophagogastric myotomy (MY) aimed at determining the role of autologous MSC in the regeneration of the lower esophageal sphincter (LES) after surgery. METHODS Syngeneic BM-MSC were locally injected at the site of MY. Histological and functional analysis were performed to evaluate muscle regeneration, contractive capacity, and the presence of green fluorescent protein-positive BM-MSC (BM-MSC-GFP(+) ) in the damaged area at different time points from implantation. KEY RESULTS Treatment with syngeneic BM-MSC improved muscle regeneration and increased contractile function of damaged LES. Transplanted BM-MSC-GFP(+) remained on site up to 30 days post injection. Immunohistochemical analysis demonstrated that MSC maintain their phenotype and no differentiation toward smooth or striated muscle was shown at any time point. CONCLUSIONS & INFERENCES Our data support the use of autologous BM-MSC to both improve sphincter regeneration of LES and to control the gastro-esophageal reflux after MY.

Abstract
In this study, we attempt to examine the feasibility of the bioactive tissue-engineered sling by using muscle precursor cells (MPCs)-seeded Poly(ε-caprolactone) (PCL) nanofiber sheet in a rat model of stress urinary incontinence (SUI). In vitro, MPCs were cultured on a PCL nanofiber sheet for one week, where the MPCs-seeded PCL nanofiber sheet showed constant twitching contraction by electrical field stimulation in an organ bath. In vivo, MPCs-seeded PCL nanofiber sheet was placed under the female rat's urethra after pudendal nerve denervation (animal model of SUI). The leak point pressure (LPP) was evaluated with the vertical tilt table after the operation for four weeks. The resulting LPP of MPCs-seeded PCL nanofiber sheet group was observed to be significantly higher than the denervation-only group's. Furthermore, PKH-26-labeled MPCs were observed under the urethral sphincter by immunohistochemistry. These results indicated that, the MPCs-seeded PCL nanofiber sheet have not only provided support for the deficient sphincter, but also actively improved the sphincter's function overall. In conclusion, this bioactive tissue-engineered sling could be used as an ideal material for the treatment of SUI.

Abstract
Adult stem cells are multipotent and self-renewing cells that contain several functions; i) migration and homing potential: stem cells can migrate to injured and inflamed tissues. ii) differentiation potential: stem cells which migrated to injured tissues can be differentiated into multiple cell types for repairing and regenerating the tissues. iii) immunomodulatory properties: stem cells, especially mesenchymal stem cells can suppress immune system such as inflammation. All those characteristics might be useful for the treatment of the digestive tract diseases which are complex and encompass a broad spectrum of different pathogenesis. Preclinical stem cell therapy showed some promising results, especially in liver failure, pancreatitis, sepsis, and inflammatory bowel disease. If we can understand more about the mechanism of stem cell action, stem cell therapy can become a promising alternative treatment for refractory digestive disease in the near future. In this review, we summarized current preclinical experiences in diseases of the digestive tract using stem cells. (Korean J Gastroenterol 2011;58:133-138).
