Abstract:

Objective To observe the immune-suppression ability of umbilical cord mesenchymal stem cells(UC-MSC) on the proliferation of peripheral blood mononuclear cells(PBMC), which were isolated from young(25~35 years) healthy, middle aged(50~60 years) healthy, and middle aged PD(Parkinson's disease) individuals and to explore what cytokines are required to induce UC-MSC to be immune-suppressive. Methods All the recruits were males. Co-culture of the PBMCs and the UC-MSC pretreated by different cytokines and measure the proliferation of PBMC were done. Results The immune-suppression ability of UC-MSC was confirmed with young healthy, middle aged healthy, and middle aged PD individuals. In our experiments, IFN-γ synergized with TNFα, IL-1α, or IL-1β in inducing UC-MSCs was proved to inhibit PBMC proliferation. The combinations of "IFN-γ+IL-1α" and "IFN-α+IL-1β" are more powerful than "IFN-γ+TNF-α" in inducing UC-MSC to inhibit the proliferation of PBMC. We also found that the PBMC proliferation of young after UC-MSC co-culture was significantly lower than that of PD patients, but the proliferation of PD patients' PBMC didn't show any difference when compared with middle aged healthy ones. Conclusions All of these results showed that the immune-suppression ability of UC-MSC is not innate, but is cytokine stimulation dependent. Furthermore, the PBMC inhibition of PD patient, together with that the PD progression did not affect the response of PBMC toward the inhibition of UC-MSC, is the direct evidence that UC-MSC might be a candidate cell type in anti-inflammation therapy of PD.
