Fig. 4. Neonatal rGM-CSF corrects increased SP-D in LPL^−/− mice.

(A) SP-D or (B) SP-A concentrations in whole-lung homogenates obtained from PND3 pups or adult WT or LPL^−/− mice that had received neonatal rGM-CSF therapy (gray bars) or PBS (control; open bars). Line shows the median value. P values are determined using the Mann-Whitney U test. n of each group is listed below x axes. Data are combined from two independent cohorts of animals.
