Adipose stem cells (ASCs) are an attractive source of stem cells with therapeutic applicability in various fields for regenerating damaged tissues because they show stemness characteristics. However, little investigation has been done to evaluate adverse responses caused by human ASCs therapy. Therefore, in the present study, a clinical assessment after human ASCs transplantation in dogs was investigated.
A total of 12 healthy male dogs were selected and divided into 4 groups: 1) saline infusion and bolus groups, and 2) ASCs infusion and bolus groups. Physical assessment and blood analysis were performed following ASCs transplantation, and the concentration of angiogenic factors, and pro- and anti-inflammatory cytokines was measured by enzyme-linked immunosorbent assay.
There were no adverse responses in vital signs among the dogs. In blood analysis, there were no remarkable findings in CBC and serum chemistry parameters. In ELISA assay, level of angiogenic and anti-inflammatory factors including MMP9, VEGF, bFGF, HGF and IL-10 were significantly increased in ASCs groups compared with control.
In conclusion, this study demonstrated that transplantation of human ASCs showed no adverse effects and could be used in dogs. Also, human ASCs could be involved in modulating secretion of angiogenic factors including MMP9, VEGF, bFGF, HGF and anti-inflammatory factor IL-10.
