title: Plaque-forming cells in human cord blood: studies on T and B cell function.
abstract: Fewer plaque-forming cells (PFC) were found in the cord blood than in adult blood. B cells of newborns seem to be functionally mature. T cells of newborns provide enough help but exert increased suppressor activity.
