Background: Mesenchymal stem cells are a potential candidate for regenerative medicine. Many factors may influence the physiological characteristics of stem cells that may lead to the alteration in their potential. Methods: The impact of age on mesenchymal stem cell characteristics was investigated in older buffaloes (aged over 10 years) and compared to younger counterparts (aged less than 2 years). Following isolation through enzymatic digestion, the mesenchymal stem cells were cultured in DMEM containing 12.5% FBS and antibiotics. Different variables indicating stem cell characteristics were evaluated at subsequent cultures. Result: The results revealed both groups displayed positive staining for alkaline phosphatase (AP) and expressed stem cell markers, including CD73, CD105 and OCT4, while remain negative for CD34. Furthermore, both sets of stem cells demonstrated the ability to differentiate into adipogenic, osteogenicand chondrogenic lineages. There were no notable variations observed between the two groups in terms of the cell yield, percentages of senescent cells, necrotic cells, dead cells and the apoptotic index. Expression of the P53 gene in RT-PCR amplicon in both groups confirms that stem cells are dividing normally as healthy cells and not tumor cells. Consequently, it was concluded from the present investigation that the age of the animal does not influence the characteristics of mesenchymal stem cells derived from adipose tissue. Thus, the stem cells derived from older and younger buffaloes are suited equally as a cell source for regenerative therapeutics.
