HBEGF expression in villous explants during culture. Immunohistochemical staining of non-cultured (A,B) and in vitro cultured (C,D) villi that were labeled with non-immune IgG (A) or antibody to HBEGF (B-D). Explants were cultured for 24 h at 20% (C) or 2% (D) O2. Bar = 50 μm. E. HBEGF immunohistochemical staining during culture at 20% (solid bars) or 2% (striped bars) O2. The intensity of labeling (grey level) was quantified by image analysis in stained sections of villi cultured for the indicated times. A one-way ANOVA demonstrated no significant differences in HBEGF labeling among the treatments shown.
