Mice and human tumor tissue sections exhibit rough surface topography compared to the normal control tissue sections. SEM images of (A) tumor sections from nude mice treated with control B16F1 cells (photographs taken at lower magnifications of 3,300 × and 4000 × and higher magnification of 12,000 ×) and SMAR1-P44 (photographs taken at lower magnification of 3,300 × and 7,500 × and higher magnification of 12,000 ×), (B) sections from human breast cancer cells of different patients. Images from normal breast tissue section and various grades of breast cancer cells: Grade I, Grade II, Grade III and giant multinucleate cells are shown. Photographs have been taken at 1000 ×, 3000 × and 8500 × magnification for all the tissue sections except for the normal breast tissue as well as Grade I tumor section wherein the highest magnification used was 27,000 ×.
