FIGURE 9.

Comparison in PCDH12 content of maternal sera in normal and pathological gestations. Sera from pregnant women in their first trimester of pregnancy were collected (see Table 1 for gestation characteristics) and analyzed by Western blot for their PCDH12 content (see supplemental Fig. S4 for a representative example of serum analysis). PCDH12 signals were quantified and plotted. The solid lines represent the means, and the dashed line is the 2-fold S.D. value for nonpathological gestations.
