Fig. 1. Regulation of EGF family expression by O2. (A)
Immunohistochemical labeling of EGF family members in cytotrophoblast cells.
Antibodies against EGF, TGF
(TGF-a), HBEGF, amphiregulin (AR),
betacellulin (BC) and epiregulin (ER) were used, as well as a non-immune goat
IgG control. (B) Antibody labeling was quantified by image analysis in
cells cultured for 24 hours at either ambient O2 levels (black
bars) or 2% O2 (gray bars). *P<0.05;
**P<0.001, compared with ambient culture.
