insuffisance ovarienne pr\u00e9matur\u00e9e<\/strong> touche environ 1 femme sur 100 de moins de 40 ans.<\/p>\nIVI a lanc\u00e9 une \u00e9tude exp\u00e9rimentale. Le but est de cr\u00e9er une technique plus efficace mais aussi moins invasive pour tester la capacit\u00e9 de r\u00e9activation des ovaires de diff\u00e9rents facteurs s\u00e9cr\u00e9t\u00e9s par les cellules souches. La priorit\u00e9 sont les patientes qui doivent recourir \u00e0 un don d\u2019ovocytes pour avoir un enfant.<\/p>\n
\u00ab Nos pr\u00e9c\u00e9dentes \u00e9tudes montrent que l’autogreffe de cellules souches ovariennes avait permis d\u2019optimiser la croissance des follicules existants. Cel\u00e0 a conduit \u00e0 des grossesses et des naissances chez les patientes ayant une faible r\u00e9ponse et un pronostic tr\u00e8s d\u00e9favorable. Au cours de cette \u00e9tude exp\u00e9rimentale, nous avons observ\u00e9 diff\u00e9rents fait. Des sources de plasma ou de facteurs de cellules souches ou de plasma sanguin de cordon ombilical, pouvaient induire diff\u00e9rents degr\u00e9s de vascularisation locale de l\u2019ovaire, de prolif\u00e9ration cellulaire. En m\u00eame temps, cel\u00e0 r\u00e9duit l’apoptose et favorise la croissance folliculaire chez des souris aux ovaires endommag\u00e9s \u00bb, explique le Pr. Pellicer.<\/p>\n
Ce traitement pourrait s\u2019av\u00e9rer efficace pour les patientes pr\u00e9sentant une faible r\u00e9serve ovarienne. Il leur donnerait alors la possibilit\u00e9 d\u2019utiliser leurs propres ovocytes avec des r\u00e9sultats encourageants.<\/p>\n
