Mixture of fibroblast, epithelial and endothelial cells conditioned media induce monocyte-derived dendritic cell maturation.
Fully matured DCs with large amount cytoplasm and copious dendritic projections were visible at the end of culturing period in the presence of MCM, TNF-α and poly (I:C), with or without FEECM. Thus, DCs generated with these maturation factors are nonadherent and have typical satellite morphology. Flow cytometric analysis using anti-CD14, -CD80, -CD86, -HLA-DR and -CD83 revealed that expression of CD14 is decreased in particular in FEECM treated DCs, on day 5 and expression of CD80, CD86 and HLA-DR was the higher when FEECM are added to maturation factor. Functionally, when DCs matured in the presence of FEECM elicited stronger MLR, reduced phagocytic activity. These results support the use of the FEECM with MCM, TNF-α and poly (I-C) as maturation factor in DC generation that could result in functionally mature monocyte-derived DCs in comparison to either alone.
