Disease:

Choriocarcinoma

Origin:

This is one of six clonally derived lines isolated from the Woods strain of the Erwin-Turner tumor by Kohler and associates by implanting into a hamster cheek pouch and then propagated on irradiated feeder layers of human fibroblasts. JEG-3 has the same DNA profile as BeWo (C0030001); it was established by serial cloning of BeWo. The cell line forms malignant tumor consistent with choriocarcinoma in nude mice. This cell line releases chorionic gonadotrophin and somatomammotrophin and progesterone. The cells are able to transform steroid precursors to estrone and estradiol. This cell line is a suitable transfection host.
