Relaxin stimulates plasminogen activator secretion by rat granulosa cells in vitro.

abstract：:Current in vivo and in vitro data indicate that progesterone (P) is required for epithelial proliferation in mammary glands of adult mice. P receptors (PgR) in adult mammary glands are under estrogenic regulation. By contrast in immature, pubertal 5-week-old mice, PgR are present only in low concentration and cannot b...
