title: Diameter increase of collagen fibrils of the mouse endometrium during decidualization.
abstract: The diameter of collagen fibrils was measured in different regions of the antimesometrial endometrium of mice on days 5, 6, and 7 of pregnancy as well as in the endometrium of virgin mice. The average diameter of fibrils of virgin mice was 39.18 nm (range: 20-80). In the region of fully decidualized cells, the averages and ranges were 45.32 nm (30-170), 89.39 nm (30-270), and 125.88 nm (20-370), respectively, on days 5, 6, and 7 of pregnancy. Thick fibrils larger than 70 nm had irregular profiles. Our results show that the increase in diameter is associated with the decidualization of the mouse endometrium.
