Pin1 ablation does not affect the development of virgin mammary glands

Genotypes	Primary ducts	Secondary ducts	Tips
MMTV-Neu/Pin1+/+	7.0±0.7	27.5±3.5	162.5±33.0
MMTV-Neu/Pin1−/−	7.3±1.5	31.0±7.6	160.5±11.7
MMTV-Ras/Pin1+/+	7.2±1.5	31.0±4.1	160.5±16.3
MMTV-Ras/Pin1−/−	6.7±1.5	30.3±8.5	149.3±28.6
Virgin mammary glands from MMTV-Neu or -Ras transgenic mice in Pin1+/+ or Pin1−/− genetic background were stained with carmine red and whole mounts were prepared. Primary ducts, secondary branches and tips and end buds were counted in a representative frame under a dissecting microscope. Three to five animals were analyzed in each cohort.
