| Outline of Final Research Achievements |
In mammals, corpus luteum (CL), formed after ovulation on ovary, is endocrine organ which repeats formation and regression (luteolysis). This study revealed that luteolysis mechanism involve outflow of luteal cells from the CL to lymphatic vessels. We suggested that matrix metalloproteinases (MMPs), which degrade extracellular matrix, secreted by luteal cells have important roles to achieve outflow of luteal cells, and showed that MMPs expression in luteal cells is regulated by PGF2α and IFNG inducing luteolysis.
