Student Project Figures Figure 35 Peculiar feature found in one of the H&E slides. Blue regions indicate the presence of positively charged molecules such as DNA, while pink areas indicate the presence of acidic (negatively charged) molecules such as proteins. This observation is consistent with those in Figure 33 (higher concentration of ribonucleoproteins on the inside of the polyp). Scale bar = 100 um.  Figure 32 Figure 33 Figure 34 Figure 35 Figure 36
