Figure 3: Analysis of angiogenesis following staining with hematoxylin and eosin in uteri of control nude mice (A), 6 months after LAM/TSC cell administration (B), following treatment with anti-EGFR Ab (C) or rapamycin (D). Representative images are shown (H&E X20). Scale bars: 100 μm. Quantification was done by counting the number of blood vessels in a field (6 fields for 8 mice for each group) as described in Material and Methods (E). Data are expressed as mean ± SEM. **P<0.01 vs control mice. ##P<0.01 vs LAM/TSC-cell administered mice.
