Figure 1. Advanced lung and somatic fetal growth in C57BL/6J (parturition = E19.5) compared to A/J (parturition = 20.5) fetuses.

Figure 1

Body weight (A), lung weight (B), and lung-to-body weight ratios (C) of C57BL/6J and A/J mice were measured from fetuses harvested at E15.5, E16.5, E17.5, E18.5, E19.5 (A/J), and E20.5 (A/J), and pups at PN0, PN1 and PN2. Prior to birth, data obtained at E19.5 and E20.5 in the A/J strain were compared to E18.5 data in the C57BL/6J strain. Values are means ± SEM of 12 animals per strain; *p< 0.05, **p< 0.01, ***p< 0.001 for A/J vs. C57BL/6J.
