PC3 (PC-3) human prostate cancer cell lines are one of the cell lines used in prostate cancer research. These cells are useful in investigating the biochemical changes in advanced prostatic cancer cells and in assessing their response to chemotherapeutic agents. Moreover, they can be used to create subcutaneous tumors in mice in order to investigate a model of the tumor environment in the context of the organism.
PC3 cell lines were established in 1979 from bone metastasis of grade IV of prostate cancer in a 62-year-old Caucasian male. These cells do not respond to androgens, glucocorticoids, or epidermal or fibroblast growth factors.
Furthermore, karyotypic analysis has shown that PC3 are near-triploid, presenting 62 chromosomes. Q-band analysis showed no Y chromosome. From a morphological point of view, electron microscopy revealed that PC3 show characteristics of poorly-differentiated adenocarcinoma. They have features common to neoplastic cells of epithelial origins, such as numerous microvilli, junctional complexes, abnormal nuclei and nucleoli, abnormal mitochondria, annulate lamellae, and lipoidal bodies.
