Fig 2. Guinea pig glucocorticoid receptor isoforms in the placentae of pregnancies delivered preterm or at term and in the presence and absence of betamethasone exposure.

Glucocorticoid receptor isoforms were measured in cytoplasmic and nuclear fractions of guinea pig placentae. Human placental tissue was used as a positive control and present in lanes 1 and 2 of Fig 2a and 2b. Fig 2a represents female guinea pig placental tissues delivered preterm and exposed to betamethasone (BTPTF) or term female placentae exposed to betamethasone (BTTF) and compared to control preterm females (CPTF) and control term females (CTF). Fig 2b represents placental tissues of male guinea pigs delivered preterm and exposed to betamethasone (BTPTM) or term male placentae exposed to betamethasone (BTTM) and compared to placentae of control preterm males (CPTM) and control term males (CTM).
