Fetal intravenous cortisol infusion does not increase surfactant protein (SFTP) -A, -B or -C mRNA expression in the lung compared to the late gestation fetus. There was only an increase in normalized mRNA expression of SFTP-A (A), SFTP-B (B) and SFTP-C (C) with age, but SFTP-D (D) expression was increased with both age and cortisol infusion. Data expressed as mean ± SEM. P < 0.05 was considered statistically significant; columns with different letters are significantly different from each other. 116-day saline-infused, open bars; 116-day cortisol-infused, black bars; 140-day saline-infused, gray bars.
