Abstract

The in vitro response of cord blood lymphocytes from full-term newborn infants and premature infants to phytohaemagglutinin (PHA) stimulation was investigated. The effect of foetal plasma on adult cellular reactivity also was studied. It was shown that foetal lymphocytes suspended in either foetal or adult plasma reacted significantly less than adult cells in adult plasma. Adult cells suspended in foetal plasma showed a significant suppression of reactivity as compared with adult cells in adult plasma. It seems that foetal plasma contains a factor which suppresses the response of adult lymphocytes to PHA stimulation. At the present, the nature of this inhibitory factor is unknown. However, our demonstration of the relationship between the level of α1-fetoglycoprotein (fetuin) and inhibitory activity in premature plasma would suggest that fetuin in foetal plasma might be responsible for its inhibitory activity.
