TGF-β1, -β2 and -β3 expressions in rat endometrium during rat pregnancy. Total endometrial proteins were collected at different days of pregnancy. β-actin blots shown were used as controls to correct for loading in each lane. Blots shown are from one representative experiment. Graphics represent Western blot densitometrical analysis. Data represent the mean ± SEM of six independent experiments (six different rats). C+: positive control (day 14 endometrial protein extract).
