Expression of CD127 (A), BCL11B (B), and RORC (C) in the endometrium during the estrous cycle and pregnancy. Endometrial tissue samples from cyclic (Cy) and pregnant gilts (Px) were analyzed by real-time RT-PCR, and data are reported as expression relative to that detected on Day 12 of the estrous cycle after normalization of the transcript amount to the endogenous ribosomal protein L7 (RPL7), ubiquitin B (UBB), and TATA binding protein (TBP) controls. Data are presented as mean with standard error. ns, not significant. **p < 0.01.
