  • Background

    The human placenta is a highly invasive tumor-like structure in which a subpopulation of placental trophoblast cells known as the "extravillous trophoblast" (EVT) invades the uterine decidua and its vasculature to establish adequate fetal-maternal exchange of molecules. In vitro-propagated short-lived EVT cell lines such as JEG-3 cells are used to study molecular mechanisms responsible for this invasiveness, which are identical to those of cancer cells; however, unlike cancer cells, their proliferation, migration, and invasiveness in situ are stringently controlled by decidua-derived transforming growth factor (TGF)-beta. These epithelial-trophoblast-like cells are therefore used in identifying genetic changes underlying epithelial tumor progression as well as gonadotrophin secretion studies.

Answer

Thank you for your enquiry. JEG-3 cells are known to express the HLA-G protein. Please note though that ab14841 is a nuclear lysate, so HLA-G protein levels are expected to be low, if at all. There are a lot of publications on JEG-3 expressing HLA-G. For example: http://www.ncbi.nlm.nih.gov/pubmed/9831130 and an update: http://www.ncbi.nlm.nih.gov/pubmed/19508383 I hope this information helps. Please do not hesitate to contact us if you need any more advice or information.
