WebConclusion: Thus, we conclude that genistein diet does not affect overall cellular proliferation or crypt morphology, other than for the modest increased crypt length measured via clearing in the ob/ob genistein group. The increase in crypt length is likely indicative of the greater accuracy of the 3D measures compared to single plane. WebTo test whether it is possible to distinguish the two categories of ROS that affect crypt proliferation in vivo, we examined the consequences of deletion of Rac1 and TIGAR.
