Abstract
Background: Mesenchymal stem cells are one of the most interesting cell sources used in regenerative medicine.
Objective: In the present study, we isolated and characterized the mesenchymal stem cells from various compartments of human adipose tissue and tunica adventitia layer of the arteries.
Methods: Tissue explant culture was done from various compartments of the human adipose tissue and tunica adventitia layer of the arteries, including adipose tissue far from the vessels, perivascular tissues that are completely attached to the vessels, and tunica adventitia layer of the arteries. After the cell culture, characterization of the cells was determined at 3rd-5th passages. Flow cytometry was performed for antigen expression analysis of CD34, CD45, CD44, CD90, CD29, CD73, and CD105. For the evaluation of cell differentiation potential, adipogenic and osteogenic differentiation was conducted under appropriate protocols.
Results: The cells were positive for CD44, CD90, CD29, and CD73 and negative for CD34, CD45, and CD105. Adipogenic and osteogenic differentiation potentials were different among the cells from various compartments. The cells derived from perivascular tissue demonstrated better adipogenic and osteogenic differentiation.
Conclusion: It is essential to characterize the cells from different tissues and compartments for different purposes in regenerative medicine.
期刊介绍：
The International Journal of Organ Transplantation Medicine (IJOTM) is a quarterly peer-reviewed English-language journal that publishes high-quality basic sciences and clinical research on transplantation. The scope of the journal includes organ and tissue donation, procurement and preservation; surgical techniques, innovations, and novelties in all aspects of transplantation; genomics and immunobiology; immunosuppressive drugs and pharmacology relevant to transplantation; graft survival and prevention of graft dysfunction and failure; clinical trials and population analyses in the field of transplantation; transplant complications; cell and tissue transplantation; infection; post-transplant malignancies; sociological and ethical issues and xenotransplantation.
