Abstract
Background: According to a number of studies, calcitriol and tretinoin are able to regulate differentiation as well as the growth and of mesenchymal stem cells (MSCs). Nevertheless, the relationship between the supernatant of macrophage and mesenchymal stem cells is still under investigation. In the present work, a comparison is made between the modulated impacts of calcitriol and tretinoin treated mesenchymal stem cell supernatant on macrophage functions. Materials and Methods: The isolation of mesenchymal stem cells was done using mouse bone marrow and the various concentrations of calcitriol (200 and 400 nM) and tretinoin (25, 50, and 100 nM) were used to pulse MSCs for 48 h. Macrophages were then applied to co-culture the supernatant of MSCs for 4 hr. Consequently, macrophages were assessed for respiratory burst. Results: ?Based on the obtained results, supernatant of bone marrow?derived MSCs pulsed with calcitriol and tretinoin can have the potential for decreasing the respiratory burst of macrophages considerably in comparison with the control group.? Conclusion: The anti?inflammatory M2 macrophage polarization can be accelerated using calcitriol and tretinoin by mesenchymal stem cells.
