A) At euthanasia, wet heart weight (mg) and tibia length (mm) was measured for each animal. Graphs show the mean heart weight: tibia length +/− standard deviation per treatment group, graphed as nude, tumor-bearing and C57Bl/6 mice. Each symbol represents the value for one mouse. B) Representative H & E staining and DAPI/WGA staining of heart sections from each treatment group of nude, tumor-bearing mice at high magnification (40×) and low magnification (10×). The average width of 100 cardiomyocytes per heart were used to obtain one value per heart, depicted in the graph.
