FIGURE 1.
Transcript expression of FOS family members in seven trophoblast cell lines. RNA was extracted from three cell lines derived from choriocarcinoma (Chorio. lines; BeWo, Jar, and JEG3), three cell lines derived from first trimester extravillous trophoblast (1st trim. EVT; HTR8, Swan 71, and SGHPL4), and a cell line derived from term trophoblast cells (Term; TCL1). All cell lines were grown according to standard culture conditions and were plated for at least 24 h. BeWo trophoblast cells exposed to 250 μm 8-bromo-cyclic adenosine monophosphate for 24 h were used as a positive control. 18 S rRNA was used as a loading control.
