Africa-Press – Guinee Equatoriale. <\/strong><\/span>Les demandes en sang dans le monde sont nettement supe\u0301rieures aux offres disponibles notamment pour certains groupes sanguins. Il faut pre\u0301ciser le sang disponible est issu uniquement des ope\u0301rations de dons de sang. Des travaux de chercheurs britanniques pourraient permettre de produire du sang humain en laboratoire.<\/p>\n

Selon l\u2019information re\u0301ve\u0301le\u0301e par la re\u0301daction de BBC, des chercheurs britanniques auraient transfuse\u0301 quelques personnes avec de petites quantite\u0301s de sang cre\u0301e\u0301 en laboratoires, l\u2019e\u0301quivalent de quelques cuille\u0300res a\u0300 cafe\u0301. L\u2019essai clinique est en cours pour voir comment se comporte ces globules artificiels.<\/p>\n

Ce projet de recherche associe des e\u0301quipes de Bristol, Cambridge, Londres et de l\u2019unite\u0301 de sang et de dons du NHS. Il se concentre sur les globules rouges qui transportent l\u2019oxyge\u0300ne des poumons vers le reste du corps.<\/p>\n

Deux volontaires ont e\u0301te\u0301 les premiers a\u0300 participer a\u0300 l\u2019essai, qui vise a\u0300 tester le sang d\u2019au moins 10 personnes en bonne sante\u0301. Ils recevront deux dons de 5 a\u0300 10 ml a\u0300 au moins quatre mois d\u2019intervalle : un de sang normal et un de sang cultive\u0301 en laboratoire.<\/p>\n

Le sang artificiel est e\u0301tiquete\u0301 avec une substance radioactive, qui est ge\u0301ne\u0301ralement utilise\u0301e dans les proce\u0301dures me\u0301dicales afin que les scientifiques puissent voir combien de temps il dure dans le corps.<\/p>\n

Le sang cultive\u0301 en laboratoire devrait e\u0302tre plus puissant que la normale.<\/p>\n

Les globules rouges durent normalement environ 120 jours avant de devoir e\u0302tre remplace\u0301s. Un don de sang typique contient un me\u0301lange de globules rouges jeunes et vieux, tandis que le sang cultive\u0301 en laboratoire est frai\u0302chement pre\u0301pare\u0301, il devrait donc durer 120 jours. Les chercheurs soupc\u0327onnent que cela pourrait permettre des dons plus petits et moins fre\u0301quents a\u0300 l\u2019avenir.<\/p>\n

Me\u0302me si le cou\u0302t de cette ope\u0301ration de fabrication de sang en laboratoires demeure e\u0301leve\u0301, il faut croiser les doigts pour sa re\u0301ussite. De nombreuses maladies comme la dre\u0301panocytose pourraient enfin connai\u0302tre des traitements efficaces.<\/p>\n
