Association between morula development and endometrial inflammation. Endometrial expression of CXCL8 (A), IL1B (B), IL6 (C), PTGES (D), PTGS2 (E), and TNF (F) was determined by real-time RT-PCR on day 6 relative to infusion. Linear correlation was performed using the total proportion of cleaved oocytes to develop to morulae from all cows.
