La pand\u00e9mie de COVID-19 a exacerb\u00e9 une crise m\u00e9dicale d\u00e9j\u00e0 pr\u00e9occupante : les p\u00e9nuries de sang dans les milieux m\u00e9dicaux.<\/strong><\/em><\/p>\n

Avec des h\u00f4pitaux pleins et des donneurs de sang potentiels mis en quarantaine \u00e0 domicile ces derni\u00e8res ann\u00e9es, les dons de sang ont diminu\u00e9 au moment o\u00f9 ils \u00e9taient le plus n\u00e9cessaires. Alors que les proc\u00e9dures m\u00e9dicales quotidiennes passaient au second plan pour les patients atteints de COVID-19, un arri\u00e9r\u00e9 de traitements s’est produit.<\/p>\n

La soci\u00e9t\u00e9 isra\u00e9lienne RedC Biotech cherche \u00e0 att\u00e9nuer les p\u00e9nuries de sang en d\u00e9veloppant des globules rouges universels dans un laboratoire qui peuvent ensuite \u00eatre utilis\u00e9s pour les patients sans avoir besoin d’un donneur.<\/p>\n

Ses globules universels produits en laboratoire suivent un processus scientifique pr\u00e9cis. Tout d’abord, les scientifiques cr\u00e9ent une \u00abbanque de cellules ma\u00eetresses<\/em>\u00bb en pr\u00e9levant des cellules souches d’un donneur avec du sang O-n\u00e9gatif universel. Les cellules souches sont ensuite cultiv\u00e9es \u00e0 une concentration tr\u00e8s \u00e9lev\u00e9e o\u00f9 elles se diff\u00e9rencient (le processus par lequel les cellules souches deviennent leurs cellules cibles) et se propagent (se multiplient).<\/p>\n

Le fondateur et PDG de RedC, Ari Gargir, explique que ce processus est assez similaire \u00e0 la fa\u00e7on dont la viande cultiv\u00e9e ou cr\u00e9\u00e9e en laboratoire. \u00abLes entreprises de viande cultiv\u00e9e prennent une cellule souche d’une vache et la transforment en composants d’un steak \u2013 muscle, tissu conjonctif et graisse \u2013 et elles composent le steak. Nous pr\u00e9levons une cellule souche humaine d’un donneur universel et la transformons en globule rouge.<\/em> \u00bb<\/p>\n

\u00ab\u00a0On estime qu’il manque au moins 100 millions d’unit\u00e9s de sang dans le monde<\/em>\u00ab\u00a0, a d\u00e9clar\u00e9 Gargir \u00e0 NoCamels dans une interview Zoom. \u00ab\u00a0Mais cette p\u00e9nurie importante et probl\u00e9matique n’impacte pas tous les pays du monde de la m\u00eame mani\u00e8re<\/em>.\u00a0\u00bb<\/p>\n

Gargir s’est fascin\u00e9 pour ce probl\u00e8me en 1990 lorsqu’il a \u00e9t\u00e9 bless\u00e9 dans un accident de parapente sur le plateau du Golan et a eu besoin d’une transfusion sanguine.<\/p>\n

Pour qu’un pays dispose d’un approvisionnement sain en transfusions sanguines, environ trois pour cent de la population doit \u00eatre un donneur, explique Gargir. Dans cet Occident, c’est plus ou moins le cas, mais d’autres pays n’ont qu’environ 1 % de donateurs ; cela laisse certains pays fonctionner avec un important d\u00e9ficit sanguin.<\/p>\n

\u00ab\u00a0Dans le monde, environ 120 millions de transfusions sanguines sont donn\u00e9es chaque ann\u00e9e<\/em>\u00ab\u00a0, d\u00e9clare Gargir. \u00ab La plupart d’entre eux se trouvent dans des r\u00e9gions \u00e0 revenu \u00e9lev\u00e9. Mais le probl\u00e8me se situe principalement dans les r\u00e9gions \u00e0 faible revenu. Plus pr\u00e9cis\u00e9ment en Afrique subsaharienne, o\u00f9 il y a beaucoup d’an\u00e9mie falciforme, d’accidents et de probl\u00e8mes d’accouchement. Des millions de personnes meurent chaque ann\u00e9e \u00e0 cause de transfusions sanguines insuffisantes et inappropri\u00e9es.<\/em>\u00a0\u00bb<\/p>\n

De plus, le mauvais temps, les jours f\u00e9ri\u00e9s et la maladie contribuent \u00e0 la p\u00e9nurie de dons. Dans le cas de COVID-19, les h\u00f4pitaux ont \u00e9t\u00e9 contraints d’annuler des op\u00e9rations ne mettant pas la vie en danger en raison d’un approvisionnement en sang extr\u00eamement bas.<\/p>\n

RedC Biotech r\u00e9duira ce d\u00e9s\u00e9quilibre gr\u00e2ce \u00e0 une production de masse standardis\u00e9e et \u00e0 une mise \u00e0 l’\u00e9chelle, ce qui rendra plus facile et moins cher la production et le transport du sang \u00e0 l’\u00e9chelle mondiale.<\/p>\n

\u00ab La partie la plus importante est que la production se fera dans une usine, dans une installation de production, et ainsi vous pouvez produire en fonction de la demande et selon une pr\u00e9vision afin de ne pas rencontrer de p\u00e9nurie<\/em> \u00bb, explique Gargir. \u00ab\u00a0Vous savez que telle saison, vous aurez besoin de plus de sang, telle saison, vous en aurez besoin de moins et vous pouvez planifier vos besoins.\u00a0\u00bb<\/em><\/p>\n

La soci\u00e9t\u00e9 a r\u00e9cemment re\u00e7u une reconnaissance internationale lorsqu’elle a remport\u00e9 la premi\u00e8re place lors de l’\u00e9v\u00e9nement inaugural \u00ab\u00a0Aviram Awards – Tech for Humanity\u00a0\u00bb, un concours de performances en direct organis\u00e9 par la Fondation de la famille Aviram et Forbes, qui s’est d\u00e9roul\u00e9 \u00e0 Duba\u00ef en mars. Le concours a r\u00e9compens\u00e9 les startups les plus prometteuses du Moyen-Orient et d’Afrique du Nord qui combinent grandes entreprises avec un fort impact sur l’humanit\u00e9. Gargir et RedC Biotech ont remport\u00e9 un grand prix de 500 000 $ et la possibilit\u00e9 d’\u00eatre encadr\u00e9s par l’homme d’affaires isra\u00e9lien Ziv Aviram, qui a cofond\u00e9 Mobileye et OrCam.<\/p>\n

Gargir a expliqu\u00e9 \u00e0 NoCamels que le prix contribuerait \u00e0 \u00ab\u00a0l’exposition et la reconnaissance qui aident \u00e0 cr\u00e9er un dialogue avec des investisseurs potentiels et une collaboration\u00a0\u00bb.<\/em><\/p>\n
