Two hypothetical models for the induction of CD44v8-10 after chemotherapy. Cancer cells expressing CD44v8-10 are present in the original tumor and clonally expand in response to anti-cancer drugs (a). Cancer cells with CD44v8-10 are absent from the original tumor, but oxidative stress caused by chemotherapy induces the ectopic expression of CD44v8-10 (b)
