چکیده

Background & Objective:  Wound dressing and healing in diabetic patients is encountered with many problems. This study aims to investigate the effect of bone marrow derived mesenchymal stem cells (BM-MSCs) on the survival of random skin flap (RSF) on Streptozotocin-induced diabetic rats (STZ) using an optical microscope. Materials & Methods:  In this study, 60 male Albino Wistar rats were used (average weight 250-300 gr). The rats were divided into six groups: 1). Health-Non (HN), 2). Health- Cells (HC), 3). Health –Sham (HS), 4). Diabetic-Non (DN) that were became diabetic by injecting STZ 70 mg/kg intraperitoneally), 5). Diabetic-Sham (DS), 6). And Diabetic-Cell (DC). In all groups, the day of surgery was considered as the zero day, on the back area of animal, the flap was created with a size of 8 × 3 cm and the BM-MSCs were performed. The sampling was performed on day 7 after surgery from the region where Transitional Zone (TZ) necrosis was initiated. Results:  BM-MSCs increased the number of blood vessels (P=0.009) and the histology parameters (wound demarcation P=0.0001, granulation tissue P=0.0001) significantly compared to the control group. But this increase was not significant in the area of the survival region. Conclusion:  It was concluded that after treatment with BM-MSCs, the wound healing process in both non-diabetic and diabetic groups was increased in accordance with histological characteristics.

The present study determined the regenerative effect of bone marrow-derived stem cells (BMSCs) on thioacetamide (TA)-induced liver fibrosis in rats. A total of 30 male Wistar rats were randomly divided into sham control and treatment groups. The rats of the sham control group were subdivided into three groups and sampled on the 14th, 18th, and 20th weeks after fibrosis induction. The rats of th...

Objective(s):Some evidence showed that calcitriol has an important role in regulating growth and differentiation of mesenchymal stem cells (MSCs). However, the interaction between mesenchymal stem cells and macrophage is not clear yet.  The current study was done to investigate the in vitro effects of calcitriol on the interactions between bone marrow-derived MSCs and rat macrophages. Material...

Both cultured Bone Marrow Mesenchymal Stem Cells (BMSCs) and non-cultured Bone Marrow Mononuclear Cells (BM-MNCs) can improve random-pattern skin flap survival. However, whether prior culture expansion of bone marrow cells is beneficial for this therapy remains unclear. In the current study, the protective effects of BM-MNCs and BMSCs derived from identical bone marrow aspirates were compared i...

Objective(s): Allergic Asthma is an inflammatory disease of the lungs that is characterized by increased infiltration of leukocytes into the airways, limiting the respiratory function. Studies suggest that a defective general regulatory system against inflammation could be a significant factor in allergic asthma. It has been shown that Mesenchymal stem cells (MSCs) have a cellular immunosuppres...

Introduction: Preconditioning of mesenchymal stem cells (MSCs) is a promising strategy to enhance the therapeutic properties of transplanted MSCs. In this study, we investigated the synergistic effects of treadmill exercise and dimethyloxalylglycine (DMOG)-preconditioned stem cells in an Alzheimer’s disease (AD) model. Materials and Methods: DMOG- treated MSCs were intravenously transplanted in...
