用小鼠动物模型证明腹水癌Ehrlich细胞可从母体进入胎儿体内 ,成为继白血病L6 1 5细胞之后第二个可引起母子代癌感染的另一类型癌细胞 .在同一妊娠的多个胎儿中 ,受母体癌细胞感染的可能只有少数或个别的胎儿 .怀孕早期和中期为这两种癌细胞从母体感染胎儿的危险期 :白血病L6 1 5和腹水癌Ehrlich细胞感染胎儿频率分别为 1 0 0 %和 35 % ;但在怀孕后期 ,它们的感染频率分别降至 4.5 %和 0 .可见 ,白血病L6 1 5细胞引起母子代癌感染的频率远远高于腹水癌Ehrlich细胞 The mouse model was used to prove that Ehrlich cells in ascites can enter the fetus from the mother’s body, becoming the second type of cancer cells that can cause maternal-child cancer infection after leukemia L6 15 cells. In multiple fetuses of the same pregnancy, Only a few or individual fetuses may be infected by the maternal cancer cells. The risk of maternal infection of the fetus during the first and second trimesters of pregnancy is at risk: the frequency of fetal leukemia L6 1 5 and ascites Ehrlich cell infections is 10% And 35%; but in the late pregnancy, their frequency of infection was reduced to 4.5% and 0. Visible, leukemia L6 15 cells caused by the frequency of maternal and child cancer infection is much higher than the Ehrlich cells in ascites
