Description
Here we compare the effects of stimulation on cord blood derived CD4+ CD25+ (Treg) and CD4+ CD25- (Thelper) cells, isolated by MACS protocols & expanded in vitro using dynabeads. Expansion was carried out at a ratio of 3 beads/cell in the presence of 1000units/ml of recombinant human IL2 for 8 days, followed by 3 days of culture without beads.
