Les cellules, au cœur du vivant | Un microcosme complexe | ARTE

La cellule est à la base de la vie. Percer ses secrets permet aujourd’hui de mieux comprendre le fonctionnement de notre corps, la source des maladies et d’imaginer de nouvelles façons d’agir sur le vivant.

Que se passe-t-il au sein de nos cellules ? En 1951, la mort d’une Américaine atteinte d'un cancer foudroyant, Henrietta Lacks, a permis de découvrir les promesses de la culture cellulaire. L’étude de ses cellules, toujours cultivées en laboratoire, a marqué un tournant dans la médecine. Grâce aux nouvelles techniques de microscopie, la science peut désormais agir sur les protéines, moteurs moléculaires et les mitochondries, qui produisent l’énergie et coordonnent les fonctions vitales. Du diabète de type 1 de l’ancien footballeur Sergi Samper à l’intervention exceptionnelle menée sur le cœur d'une fillette, la recherche cellulaire transforme notre compréhension des maladies et fait émerger de nouvelles thérapies.
