Choriocarcinoma Cells (CCC)

Choriocarcinoma is a malignant, trophoblastic cancer, usually of the placenta. It is characterized by "early hematogenous spread to the lungs. It belongs to the malignant end of the spectrum in gestational trophoblastic disease (GTD). Rarely, choriocarcinoma occurs in primary locations other than the placenta; very rarely, it occurs in testicles. Although trophoblastic components are common components of mixed germ cell tumors, pure choriocarcinoma of the adult testis is rare. It is also classified as a germ cell tumor and may arise in the testis or ovary. JEG-3 and BeWo are the commonly cultured human choriocarcinoma cells.
