Primary in vitro antibody response in human cord blood lymphocytes
Abstract:
Human cord blood lymphocytes were stimulated with trinitrophenyl--polyacrylamide beads (TNP--PAA) in order to induce a primary IgM anti-TNP response. With few exceptions, no anti-TPN response was obtained, whereas peripheral blood lymphomonocytic cells (PBL) from 18-mth-old children were able to respond to TNP-PAA. The addition of lipopolysaccharide (LPS) or of mitomycin-treated adult PBL to cultures of cord blood lymphocytes significantly enhanced their anti-TNP response, thus showing that functional anti-TNP B cell precursors are present in the human neonate.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
