Induction of Macrophage M2b/c Polarization by Adipose Tissue-Derived Mesenchymal Stem Cells

iNOS mRNA relative expression in different groups of Mφ. Nonactivated Mφ upregulate mRNA expression of iNOS after LPS induction. Both the nonactivated Mφ and the LPS-induced M1-Mφ downregulate mRNA expression of iNOS after ADMSC-CM induction. The fluorescence intensity of the IL and IL-CM groups does not exceed the fluorescence threshold in 40 cycles in RT-PCR.
