Research Abstract |
We have proven that low serum cultured adipose derived mesenchymal stem cells (LASC) suppress T cell proliferation and induce polarization of macrophages into immunomodulatory M2 type, and that these effects of LASC were much stronger than high serum cultured adipose derived mesenchymal stem cells (HASC) or bone marrow derived mesenchymal stem cells (BM-MSC). Inthis study, we studied the mechanisms involved in the immunosuppressive functionof LASC by comparing with HASC or BM-MSC. We found by neutralization experiment and stimulation experiment that LASC derived PGE2 and IL-6 are necessary for the polarization of M2 macrophages, and that PGE2 function via EP4 receptor.
