There was no difference in SpeC-induced proliferation or expression of CD54 by T cells after 4 day incubation in HS or FCS. The differences between the expression of CD25 and CD103 in unstimulated cultures versus SpeC-stimulated HS cultures were highly significant (P < 0·001), although the SpeC-induced stimulation was much stronger in FCS for both these parameters. The columns represent counts per minute (cpm) or percentages of T cells expressing each marker after subtraction of the values observed for unstimulated cultures.
