06 - As células-tronco humanas podem ser obtidas e colocadas em meios de cultura 
adequados para se diferenciarem em células formadoras de tecidos especializados. 
Adaptado de Ciência e Vida, "O Globo", 10/07/01. (200) 
Cientistas acreditam que dentro de alguns anos poderão produzir células suficientes 
para tratar pacientes com doenças graves no coração, no fígado ou nos pulmões. 
a) Em que fase da formação embrionária pode-se obter o maior número de células 
tronco? Justifique sua resposta. 
b) A partir de células-tronco, que folhetos devem ser produzidos para originar células 
musculares e células hepáticas?
