Mature monocyte-derived DCs obtained with (CM+) or without (CM-) conditioned medium from GFs were used to stimulate allogeneic CD4+ T cells purified from the PBMCs from two donors (PBMC1 and PBMC2); thymidine incorporation is expressed in counts per minute (cpm).

<p>Mature monocyte-derived DCs obtained in the presence of CM from GFs displayed a significantly capacity than controls to stimulate the proliferation of allogeneic CD4+T cells. Mean ± SD of triplicates are shown and results are representative of two independent experiments. *Significant difference (P = 0.002) and **Significant difference (P<0.001).
