Clusterin expression during mouse mammary gland development in vivo. Total RNA was isolated from mammary glands at different stages of postnatal development and analyzed by Northern blot. Virgin mice: 5, 7, 12 and 18 weeks after birth; Pregnant mice: 2, 5, 12, and 18 d after onset of pregnancy; Lactating mice: 2, 7, 12, and 20 d after onset of lactation; Involuting mice: 1, 2, 3, 5 and 6 d after onset of involution.
