Examination of the Therapeutic Potential of Mouse Oral Mucosa Stem Cells in a Wound-Healing Diabetic Mice Model.

ABSTRACT: Diabetic wounds' delayed healing response is still considered a major therapeutic challenge. Stem cells and derived cellular products have been an active field of research for novel therapies referred to as regenerative medicine. It has recently been shown that human oral mucosa stem cells (hOMSCs) are a readily accessible source for obtaining large quantities of stem cells. This study evaluates the potential of mouse oral mucosa stem cells (mOMSCs) to enhance wound healing in a diabetic (db/db) mouse model by morphological and histological analysis. We show that mOMSCs-treated wounds displayed a significantly faster wound-healing response (p ? 0.0001), featuring faster re-epithelialization and a larger area of granulation tissue (p ? 0.05). Taken together, these results suggest that oral mucosa stem cells might have therapeutic potential in diabetic wound healing.

Project description:IntroductionLeptin, a 16 kDa circulating anti-obesity hormone, exhibits many physiological properties. Recently, leptin was isolated from saliva; however, its function in the oral cavity is still unclear. In this study, we investigated the physiological role of leptin in the oral cavity by focusing on its effect on wound healing in the oral mucosa.MethodsImmunohistochemical analysis was used to examine the expression of the leptin receptor (Ob-R) in human/rabbit oral mucosa. To investigate the effect of leptin on wound healing in the oral mucosa, chemical wounds were created in rabbit oral mucosa, and leptin was topically administered to the wound. The process of wound repair was histologically observed and quantitatively analyzed by measuring the area of ulceration and the duration required for complete healing. The effect of leptin on the proliferation, differentiation and migration of human oral mucosal epithelial cells (RT7 cells) was investigated using crystal violet staining, reverse transcription polymerase chain reaction (RT-PCR) and a wound healing assay, respectively.ResultsOb-R was expressed in spinous/granular cells in the epithelial tissue and vascular endothelial cells in the subepithelial connective tissue of the oral mucosa. Topical administration of leptin significantly promoted wound healing and shortened the duration required for complete healing. Histological analysis of gingival tissue beneath the ulceration showed a denser distribution of blood vessels in the leptin-treated group. Although the proliferation and differentiation of RT7 cells were not affected by leptin, the migration of these cells was accelerated in the presence of leptin.ConclusionTopically administered leptin was shown to promote wound healing in the oral mucosa by accelerating epithelial cell migration and enhancing angiogenesis around the wounded area. These results strongly suggest that topical administration of leptin may be useful as a treatment to promote wound healing in the oral mucosa.

Project description:BackgroundAdipose-derived mesenchymal stem cells (ASCs) therapy is emerging as a novel therapeutic option for the treatment of a variety of diseases including diabetes and diabetic wound healing. Multiple studies indicate that ASCs could promote wound healing and reverse diabetes. However, whether ASCs from diabetic donors retain their therapeutic functions and the mechanisms of how ASCs contribute to wound healing remain largely unknown. In this study, we explored the cutaneous wound healing ability of ASCs collected from C57BL/6 mice that had been rendered diabetic with streptozotocin (STZ).MethodsASCs were harvested from adipose tissues of type 1 diabetic (T1D) or normal C57BL/6 mice. Cell phenotypes were evaluated by flow cytometry analysis, and cell differentiation into adipocytes, chondrocytes, and osteocytes was compared. Secretions of transforming growth factor β (TGF-β1), basic fibroblast growth factor (bFGF), and vascular endothelial growth factor (VEGF) by ASCs were assessed by ELISA. Migration and proliferation of fibroblasts co-cultured with T1D ASCs or control ASCs were also compared. The therapeutic effects of T1D and control ASCs in promoting wound closure were measured in vivo in a T1D wound mouse model. Granulation tissues were collected and stained with H&E at 14th day. CD34 and collagen I were detected by immunohistochemistry. Expressions of IL-6, α-SMA, CD31, collagen I, and collagen III were quantified by real-time PCR. GFP-expressing ASCs were used to trace in vivo cell differentiation.ResultsT1D ASCs and control ASCs showed similar expression of cell surface markers (CD29, CD34, CD105) and proliferation pattern. They can both differentiate into different cell types. T1D ASCs secreted similar amounts of VEGF and bFGF, but less TGF-β compared with control ASCs. Like control ASCs, T1D ASCs promoted the proliferation and migration of skin fibroblast cells. When injected in cutaneous wound of T1D mice, T1D ASCs increased wound closure and hair follicle regeneration at a comparable extent as ASCs. Mice receiving T1D ASCs or ASCs exhibited significantly higher expressions of collagen I, collagen III, and CD31 and reduced expression of IL-6 in wound tissues. Immunohistochemistry staining showed increased angiogenesis in mice receiving ASCs as was evident by increased CD34+ cells and collagen I staining. GFP+ ASCs injection showed that ASCs differentiated into fibroblasts and endothelial cells in vivo.ConclusionsOur results suggest that T1D ASCs could accelerate cutaneous wound healing. Mechanisms may include increasing fibroblast growth and migration, skin angiogenesis, and differentiation into fibroblasts and endothelial cells. This study provides evidence that diabetic ASCs may be used as a therapeutic option in cutaneous wound healing in diabetic recipients.
