LOS ANGELES (EFE) .- During pregnancy, the exposure of nicotine in embryonic cell communication affects cell growth and changes the work of gene-regulating functions such as heartbeat, according to a study by Stanford University of America.
Joseph Wu, director of the Stanford Cardiovascular Institute and the author of the research, on Thursday, on Cell Press, said that in three weeks the exposure to nicotine may "have a negative effect on the different organs that develop the embryonic" pregnancy.
The research provides information on new products, such as electronic cigarettes, patches and nicotine-containing gums, such as quitting and cigar smoking as an alternative to consumption.
"Unfortunately, the introduction and dissemination of new nicotine products, such as e-cigarettes, compare recent advances in tobacco reduction during pregnancy," said the report.
The researchers examined 12,500 embryonic stem cells (hESC derivatives) of human embryos, related to the growth of brain, heart, liver, blood and muscles, among others.
Wu and his team also found that the survival of the cells had decreased, and nicotine can affect embryonic development from the first stages.
Additionally, "the embryo reduces the size of the body, damaging the damaging molecules called reactive oxygen" and creates deformations in the embryonic body development.
New methods also offer better research into embryonic stem cells, but do not take into account other factors, such as exercise, stress, diet or hormonal changes.
"An important involvement of our research is the validation of a new method for assessing the development of human embryo developed and the toxicity of the environment," said Wu.
