Fig. 3. Reduced alveolar development in mammary glands of Dgat1^–/– mice. Epithelial and luminal areas were quantified in Dgat1^+/+ (white bars) and Dgat1^–/– (black bars) mammary glands using digitalized images of the histology sections at P18 and L1. Area was quantified in five random fields. n=4 Dgat1^+/+ mice; n=5 Dgat1^–/– mice. ^*P<0.05; ^**P<0.01
