We sought to determine if the changes in umbilical blood proteins observed were related either to the onset of labor or to the gestational age of the infant. No significant changes were observed for PAI-1, VEGF, or FGF-2 in association with labor in either group. Similarly, umbilical cord oxygen levels were unaffected in our subjects (Supplemental Figure 1). There was also no change in PAI-1 or VEGF associated with GA. There was a significant negative correlation of FGF-2 with GA for controls that could not be seen in IUGR patients (supplemental Figure 2). FGF-2 has previously been reported to gradually decrease in fetal circulation after 20 weeks in normal pregnancy (Hill et al., 1995).

Hill, D.J., Tevaarwerk, G.J., Arany, E., Kilkenny, D., Gregory, M., Langford, K.S., and Miell, J. (1995). Fibroblast growth factor-2 (FGF-2) is present in maternal and cord serum, and in the mother is associated with a binding protein immunologically related to the FGF receptor-1. J. Clin. Endocrinol.
