cell trans·for·ma·tion

morphologic and physiologic changes including loss of contact inhibition resulting from infection of an animal cell by an oncogenic virus.


change of form or structure; conversion from one form to another. In oncology, the change that a normal cell undergoes as it becomes malignant. In statistics a functional change to the variable.

bacterial transformation
the process of intercellular transfer of genetic information in which a small portion of the total DNA of a lysed bacterium enters a related bacterium and is incorporated into the DNA genome of the recipient.
cell transformation
the changes in types of proteins expressed and growth characteristics that take place in cells infected by some viruses, including tumor formation by retroviruses.
