Rull et al. aimed to profile whole-genome differential gene expression in the first trimester placental tissue in cases of recurrent miscarriage (RM) compared to gestational age-matched uncomplicated pregnancies. Placental tissue samples were obtained during elective surgical abortion of uncomplicated pregnancy or uterine curettage due to recurrent incomplete or delayed miscarriage. The recruited RM patients had experienced at least three consecutive miscarriage events.
