Production of surfactant DSPC in the developing lung of Balb/C mice. Relative DSPC content (in μg inorganic phosphorus/mg dry wt) in Balb/C fetal lungs according to developmental time (day). A one-hour mating window was used (± 0.02 day). Within the developmental time window studied, DSPC varied significantly (P < 0.0001, one-way ANOVA) between GD 18.50 and 18.75 (P < 0.05, Tukey's multiple comparison test).
