found that fibronectin deficiency

xinhuanet.com Tokyo on 8 May, Cheap St.Louis Browns Jerseys (reporter Lan Jianzhong) women increased with age, the chance of pregnancy will be reduced, and the older pregnancy prone to abortion and abnormal. A research team in Japan has found that, women in the egg cells connected chromosome laminin decreases with age, leading to infertility, abortion or birth babies "problems".

team Fujita Health University Assistant Tsutsumima Kiko leadership in the new issue of America "Public Library of science synthesis volume" the report said, they asked 8 19 to 49 year old women with ovarian provided by disease, study its internal egg cells, and analyze the relationship between age and laminin number. The researchers found that, although there are Cheap Rockies Jerseys individual differences, but the older women, egg cells adhesion protein less.

The

researchers in the experiments with mice, found that fibronectin deficiency, abnormal chromosome probability will be increased. This is because the adhesion protein decrease, in the egg cell formation, chromosome Cheap Cardinals jerseys may not be evenly distributed, Cheap Mets jerseys and the normal standard, the chromosome number of egg cells is not more is less. Therefore, the fertilized egg will be abnormal, leading to increased frequency of abortion, or give birth to children with Down's syndrome.

researchers think, though not fertility sterility simply by laminin caused less, but a survey of women and sticky gene even protein related to, whether they are prone to chromosome abnormality.

Tsutsumima Kiko points out: "if be developed to stop the laminin reduction method, it may reduce the risk of chromosome abnormalities in elderly pregnancy."
