Evidence that cervical cancer cells secrete IL-2, which becomes an autocrine growth factor

We present evidence that cervical cancer cells express a functional IL-2 receptor (IL-2R). In fact, by RT-PCR we obtained that the IL-2R is present in CALO, and INBL cells, and that it consisted of the αIL-2R, βIL-2R, and γIL-2R chains. We also found that IL-2 is a growth factor for these cell lines...
