THE CHANGES OF CYTOKINE LEVEL IN THE BLOOD OF COPD PATIENTS AFTER ALLOGENEIC UMBILICAL CORD-DERIVED MESENCHYMAL STEM CELL TRANSPLANTATION WITH PLALETE RICH PLASMA
Main Article Content
Abstract
Objective: To study the changes of cytokine level in the blood of COPD patients after allogeneic umbilical cord-derived mesenchymal stem cell (UC-MSC) transplantation with platelets rich protein. Subjects and methods: Plasma of 10 COPD patients treated by internal medicine and 18 ones by UC-MSC transtplantation were collected at the National Lung Hospital and Van Hanh Hospital at the time points before transplantation (0) and after 1, 3, 7 and 12 months of transplantation. The quantitative concentrations of cytokines were measured by ELISA. Results: Before the treatment, the cytokine levels of the control group were not significantly higher than that of the treated group (p>0,05). After the treatment, in the control group, IL-8, IL-1β, IL-6, IFN-γ and IL-10 levels tended to increase, while TNF-α and VEGF decreased (p>0,05). In contrast, the cytokine levels of the treated group decreased; IL-10 and VEGF expression increased (p<0,05). Conclusion: The inflammatory cytokine levels of UC-MSC transplantation with platelets rich protein patients decreased and VEGF increased after treatment, which may limit the inflammation and enhanced the tissue regeneration.
