Comparison of cytokine levels produced by DC from SP or DP HPC cultures.

Supernatants of mature DCs, prepared as described in “Materials and methods,” were assessed by ELISA for the indicated cytokines. Each point indicates the supernatant of an individual DC culture. CD1a-DC (○): DCs differentiated from CD1a⁺CD14⁻precursors in SP or DP HPC cultures; CD14-DC (▵): DCs differentiated from CD1a⁻CD14⁺ precursors in SP or DP HPC cultures.
