VALENCIA (EUROPA PRESS) The director of research’n of the Valencian Infertility Institute (IVI), Charles Sim’n, present’ a study on the population’n células mothers that exist in the &number;tero of women, and that enable the regeneration’n monthly of the endometrium with the aim of explaining diseases such as endometriosis, which affects up to 40 per cent of women and causes enormous pain, bleeding and infertility, así as cáncer of endometrium, the second más common in the female genital tract afterés of the breast.
The scientificífico, present’, this study, called ‘Adult Progenitor stem Cell population in the Human Mice Endometrium’, in the International Symposium on Reproductive Medicine, which is developed in the Museum príncipe Felipe, Valencia with the participation’n más of 200 international researchers. In this regard, explanation’ that two-thirds of the endometrium, the mucosa that covers the inside of the &number;tero whose function’n you can host the zygote afterés of the fecundaci’re allowing your implantaci’n, are lost each month with the period if the woman does not become pregnant, but there is always the layer basalis, a tissue of a centímeters of thickness that allows the generation’re full. Así, the project aims at identifying’n and study of the people’n células madre adult human endometrium, and once known the células normal, studyá differences in the cáncer, and endometriosis. To identify this population’n, detail’ before’ a biopsy of the endometrium of the woman, sought asylum the células, were selected and implanted in a rat’n immunosuppressed and "it was possible’ make these to 10,000 células a endometrium full". "This –recalc’– it is a proof that these células give rise to a endometrium". Sim’ve highlighted wi’ the obtenci’n of these células adult stem offers a great power terapétherapeutic because it allows us to better understand diseases diagnosed for 150 to&years but still’is unknown c’mo occur such as endometriosis, which arises when there are foci of endometrial tissue outside the uterine cavity. The hip’thesis is that this situation’n cr’nico-degenerative, which cause infertility, bleeding and strong menstrual pain and ne sex, to the point that it has had to operate on patients to remove the &number;tero and the ovaries, may be caused by a disordered growth of this population’n células mother. In the same way, study if the cáncer of endometrium arises because "está population’n crazy". METHOD NON-INVASIVE. In the same way, the researcher, IVI, Francisco Domínguez, present’ the study, ‘Diagnosis’forecast non-invasive health of the embri’n’, a new tétechnique in the breeding’n assisted that prevents the extracci’n of a célula del embri’n for further study, with the which prevé to achieve a &number;nico embri’n, that esté healthy and to ensure your implant and prevent ace’ pregnancies m&number;multiple. Until now extraía célula del embri’n to know his health, but this study has allowed to identify 10 proteínas that consumes the embri’n of the 120 studied that are thought to be those that guarantee the implantaci’re. This análysis of the environment in which they live the embri’n, with the that it prevents the extracci’n must be done in the fifth díto the growth of the blastocyst, as s’lives six d’s out of the mother, and just before you go to be implemented and the result is known in two hours. Once published, this first stage of the study, which is expected to be approved this week, to startá phase retrospective, in which analyzing the environment in which they live these embryos, previously frozen, predictá its ability to implantaci’n, and verifyá – if the woman stayed with us’ pregnant, that showá the reliability of the méeverything. Así, confían, in order to implement this tétechnique on the term máximo a&bath;or, with which prevé improve the rate implantacional natural 30 percent of the human species because they allowá select the embri’re healthy with más chances of ésuccess. Sim’n&bath;’ that there is scientificígraphics that are opposed to the biopsy of a embri’n to learn about your health by believing that it can decrease up to 10 percent of the ésuccess of implantaci’re by removing one of the six células in which in that time it has been divided, although apunt’ that there is a serious study that confirms this hip’thesis, and in fact, is&bathrooms;’ that his experience in the IVI contradicts it. In any case highlighted wi’ that we are before a "was biol’magic" and that the reproduction’n assisted must alsoén to adapt to this trend by the advantages that it brings. For the &number;last, the professor Antonio Pellicer presented the results of a study on an animal model of endometriosis that has been created to investigate the vascularizaci’n and the factors that affect it. This advance couldíto open new v’s terapéuticas for this disease así as to improve the quality of life of women affected of endometriosis. NEW CONTRACEPTIVE PILL. For its part, a researcher at the Karolinska Institute in Stockholm, informá ma&bath;ana of the research on a new pípill contraceptive based on blocking the implantaci’n del embri’re in the endometrium, that s’it may be between four and seven días afterés of the ovulaci’re. Así, s&number;n beyon’ Sim’n this pípill makes the endometrium "not responsive" so that "when it comes to embri’n to the wall of the &number;tero bounces, and prevents the implantaci’n". This pípill s’what you take’to those d’s for vía vaginal.
