(18) We employed a sensitive in vitro amnion invasion assay to examine the relationship of the invasive ability of numerous mouse and human tumor cell lines and their variants to their ability to spontaneously or artificially metastasize; we also studied possible enzymatic activities involved in the in vitro invasion process.
(19) (5) In the case of transmission the frequency of cellular infiltration of the amnion and umbilical vein wall is significantly higher than in the cases of normal gestations.
(20) All amnions restrict AFP movement into maternal serum, but some are distinctly more restrictive than others; in such cases, a relatively greater increase in amniotic fluid AFP concentration would likely have to occur from a fetal lesion before being reflected in maternal serum.
