Introduction: In inflammatory situations, SHED-MSCs exhibit properties that can modulate the immune response. These cells interact with various types of immune cells, including naïve or M1 macrophages. We believe that when SHED-MSCs are co-cultured with M1 macrophages, it may have an impact on oxidative stress markers such as total antioxidant capacity (TAC) and malondialdehyde (MDA), a peroxidation product. To examine the connection between TAC and MDA as biomarkers for oxidative stress in the supernatant of co-cultured SHED-MSCs and M1 macrophage cells.
Methods: The differentiation of the THP-1 monocyte cell line resulted in the formation of M1 macrophage cells. Once confirmed through flow cytometry, these cells were co-cultured with SHED-MSCs in a trans-well system. The levels of TAC and MDA in the supernatant were then measured using FRAP and TBARS methods, respectively.
Results: In the co-cultures supernatant, the average TAC levels in M1/SHED-MSCs were significantly higher compared to the control group. On the other hand, the average MDA concentrations in the co-cultures supernatant were lower compared to those of controls.
Conclusion: SHED-MSCs have the ability to alter oxidative stress indicators through their interaction with M1 macrophages. This indicates that SHED-MSCs have the ability to alter inflammation markers and modulate the inflammatory condition.
