iPSC-MSC-DCs inhibited the effects of mature dendritic cells (mDCs) on peripheral blood mononuclear cell (PBMC) proliferation. a Representative experiments assessing lymphocyte proliferation. b The effects of iPSC-MSC-DCs on the function of mDCs in lymphocyte proliferation. The findings were confirmed using U-iPSC-MSCs and A-iPSC-MSCs and the data represent the means ± SD of six independent experiments using U-iPSC-MSCs. *P < 0.05. CFSE carboxyfluorescein diacetate succinimidyl diester, iPSC-MSC-DCs dendritic cells co-cultured with induced pluripotent stem cell-mesenchymal stem cells from day 5 to day 7 in the presence of GM-CSF, IL-4, and LPS.
