Figure 4. Flow cytometric analysis of
endocytic activity of DCs. Mature DCs (A), DCs treated
with 50% CSC culture supernatant (B), and DCs treated
with 50% CSC culture supernatant in presence of neutralizing
TGF-β2 antibody (C). The empty histograms represent the
uptake of FITC-dextran at 4 °C. The histogram is from one
representative experiment out of three performed.
