Figure 6: Progesterone receptor (PR) and host markers expression on T. spiralis cells. (a) T. spiralis cells were stained with anti-mCD3, anti-mCD19, and anti-mMac-1 (upper row); cultured in presence of media (green line), E2 (orange line), P4 (blue line), and T4 (pink line) and stained with anti-Cav-1 of T. spiralis and anti-PR specific antibodies (middle row). (b) Ovary-derived cells were stained with anti-PR antibody as a positive control for PR.
