The expansion kinetics of PBLs revealed a highly significant increase ( p < 0.001) in cell numbers in the client-owned group starting from day 8 and in the short-term group starting from day 10, and a significant increase ( p < 0.01) in the long-term shelter group starting from day 10 after CD3/CD28 MicroBeads-mediated activation, compared with non-stimulated cells.
