Progesterone induces surface expression of EMP2 in RL95-2 cells. RL95-2 cells were treated for 72 hours with 25 μM progesterone, 20 μM estradiol, or a vehicle control, and processed for confocal microscopy with antibodies for EMP2 (FITC) and γ-adaptin (Rhodamine). Images were captured at a magnification of 600×. Scale bar, 10 μM. The experiment was repeated at least 3 times with similar results.
