Figure 4.

Comparison of the T-cell stimulatory capacity of cord and adult dendritic cells (DCs) in medium alone (med) or after stimulation by LPS, early apoptotic (apo) or necrotic (nec) lymphoblastoid cells (LCLs) for 36 hr. The cord and adult DCs were irradiated before coculturing with allogeneic adult T cells at different DC : T cell ratios as indicated. T-cell proliferation was measured by BrdU incorporation and the data are expressed as mean absorbance at A₄₅₀ ± SEM of three independent experiments.
