Secretion of C-C chemokines by cord and adult blood cells.
MIP-1α, MIP-1β, and RANTES secretion in cord and adult blood were compared using 3 groups of cells: CBMC and ABMC (n = 15 pairs); purified lymphocytes CBL and ABL (n = 10 pairs); and purified monocytes (n = 6 pairs). CBMC, ABMC, CBL, and ABL were incubated with PMA (5 ng/mL) for 24 hours. Monocytes from cord and adult blood were incubated with LPS (5 ng/mL) for 24 hours. Results are shown as chemokine concentrations in the supernatants (mean ± SEM [standard error of mean]). *Indicates cord versus adult,P < .05.
