EpCAM and CD44 antibodies did bind distinctively throughout the FNAB tumor sample as seen through multiple z-axis images with 40 μm from the surface of the tumor (z/5), through the interior of the tumor (z/7 and z/9), with completion on the opposing side, 30μm from the surface (z/11) (Fig 3B). This evidence concerns the gene CD44 and neoplasm.
