ABSTRACT
PURPOSE:
The aim of study was to compare the differentiation capacity of mesenchymal stem cells (MSCs) obtained from human bone marrow (BM) according to the age of the donors. MATERIALS ANDMETHODS:
MSCs were isolated from the BM of young (n=16, 12.5+/-5.8 years) and elder (n=4, 48.5+/-7.2 years) patients with the consent of them. We analyzed the cell morphology and the cell surface markers of the MSCs. In addition, we assessed the cell senescence with serial cultures from both age groups. Cell pluripotentiality was analyzed by osteogenic, chondrogenic, and adipogenic induction media. We performed RT-PCR, a measurement of expression of alkaline phosphatase, and staining with von Kossa, safranin O, and oil red O stain.RESULTS:
All of the MSC samples tested, irrespective of the age of the donors, MSCs were all successfully isolated from twenty bone marrows. However, the number of cells of from the young donors was five times greater than that of the elderly donors. Senescence was observed over 10 passages in both age groups. The immunophenotypes of both age groups showed similar patterns. MSCs obtained from young and older donors showed the potential to differentiate into osteogenic, chondrogenic, and adipogenic lineages with no difference for both age groups.CONCLUSION:
Our study supports that age does not influence the pluripotential capacity of human BM derived MSCs.
