Osteogenic Differentiation of Rat Mesenchymal Stem Cells from Adipose Tissue in Comparison with Bone Marrow Mesenchymal Stem Cells: Melatonin As a Differentiation Factor
Authors
Abstract:
Background: Adipose-derived stem cells (ADSC) could be an appealing alternative to bone marrow stem cells (BMSC) for engineering cell-based osteoinductive grafts. Meanwhile, prior studies have demonstrated that melatonin can stimulate osteogenic differentiation. Therefore, we assayed and compared the melatonin effect on osteogenic differentiation of BMSC with that of ADSC. Methods: Mesenchymal stem cells (MSC) were isolated from the bone marrow and fat of adult rats. Both cell types were cultured in osteogenic medium in the absence and presence of melatonin at physiological concentrations (20-200 pg/ml). After 4 weeks, the expression of osteocalcin gene was analyzed by reverse transcription-PCR, alkaline phosphatase (ALP) activity was assayed and alizarin red S and von Kossa staining were done. Cell viability and apoptosis were also assayed by 3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide, a tetrazole (MTT) and flow cytometry, respectively. Results: The osteoblastic differentiation of ADSC as demonstrated by ALP activity was less than that of BMSC. The amount of matrix mineralization has shown by alizarin red S and von Kossa staining also showed statistical differences between the two MSC. The incidence of apoptotic cells was higher among ADSC than BMSC. The flow cytometry proves that cell growth reduction is due to a decrease in the number of the cells entering the S phase of the cell cycle. MTT assay indicated that viable cells were fewer among ADSC than BMSC in control groups. Conclusion: The results of the study suggest that BMSC have greater osteogenic potential than ADSC and that melatonin promotes osteogenic differentiation to BMSC, but has a negative effect on ADSC osteogenic differentiation.

full textHarvesting of bone marrow mesenchymal stem cells from live rats and the in vitro differentiation of bone marrow mesenchymal stem cells into neuron-like cells
In the bone marrow, there are certain populations of stem cell sources with the capacity to differentiate into several different types of cells. Ideally, cell transplants would be readily obtainable, easy to expand and bank, and capable of surviving for sufficient periods of time. Bone marrow mesenchymal stem cells (BM-MSCs) possess all of these characteristics. One of the most important benefi...
full textIsolation, Characterization and Differentiation of Rat Adipose Tissue Derived Mesenchymal Stem Cells
Introduction: Mesenchymal stem cells have the potential of self-renewal and differentiation into different cell types, including blood cells, heart, nerves and cartilage, and have unlimited power for division. These cells can be obtained from cord, before implantation from fertilized cells and also from various tissues of adults although the differentiation power and the ability to reproduce ...
