This is something created by the Wyss Institute in Boston, and what they have done here, if we can run the little video, is to take cells from an individual, turn them into the kinds of cells that are present in the lung, and determine what would happen if you added to this various drug compounds to see if they are toxic or safe.
É unha creación do Wyss Institute  en Boston, e o que fixeron,  se poñemos en marcha o vídeo, foi coller células dun individuo, transformalas en células que hai nos pulmóns, e ver que acontece se se engaden varios compostos para ver se son seguros ou tóxicos.
