So you could really say that researchers trying to understand the cause of disease without being able to have human stem cell models were much like investigators trying to figure out what had gone terribly wrong in a plane crash without having a black box, or a flight recorder.
Podemos mesmo dizer que, para os cientistas, tentar perceber a causa de uma doença sem terem acesso a modelos de células estaminais humanas é como os detetives tentarem perceber o que aconteceu de errado num acidente aéreo sem terem a caixa negra ou o registo de vôo.
