Fig. 3From: Preterm birth impairs postnatal lung development in the neonatal rabbit modelSurfactant expression in term and preterm pups at birth. a, b Surfactant protein B and C mRNA expression is significantly lower in preterm pups before the first breath (n = 5). c The level of surfactant protein B in lung homogenate is lower in preterm pups, compared to term pups (n = 10–15). *p < 0.05Back to article page
