Smudge cells are. CLL cells ruptured during smear preparation. We hypothesized. that smudge cell formation is inversely correlated with expression. of vimentin, a cytoskeletal protein and prognostic marker, and. that the percentage of smudge cells would predict prognosis in.
The main difference between the Acadia and Traverse is their styling and price. Acadia is expensive, and holds standard equipment when compared to the Traverse. The Acadia is available for around $31,740, whereas the Traverseâs price starts at $29,224. Both of them have the same destination charges, which are $775.
Summary: Vessels have perforations at the end plates while tracheids do not have end plates. Tracheids are derived from single individual cells while vessels are derived from a pile of cells. Tracheids are present in all vascular plants whereas vessels are confined to angiosperms.Tracheids are thin whereas vessel elements are wide. Tracheids have a much higher surface-to-volume ratio as compared to vessel elements.Vessels are broader than tracheids with which they are associated.Morphology of the perforation plate is different from that in tracheids.racheids are thin whereas vessel elements are wide.
