WebCrypts of the colon can reproduce by fission, as seen in panel C, where a crypt is dividing to form two crypts, and in panel B where at least one crypt appears to be fissioning. Most crypts deficient in CCOI are in clusters of crypts (clones of crypts) with two or more CCOI-deficient crypts adjacent to each other (see panel D). [7] WebCADs were subdivided into four groups: i) Crypts with fission distortions, ii) Crypts with length distortions, iii) Crypts with outlines distortions and iv) Crypts with axial polarity distortions. The most frequent CAD group hadaxial polarity distortions (33.4%), and the less frequent CAD group, outline distortions (21.1%) (P< 0.05).
