Figure 7-7. Epithelial and Fibroblastic Morphologies Exhibited by 



theCHO-KI Cell. 



Note: (A) shows the standard epithelial morphology usually adopted by the 

 cell. (B) illustrates the highly fibroblastic form assumed by a potentially 

 contact-inhibited cell isolated from a population treated with the known 

 carcinogenic agent chromium trioxide.
