Cientistas chineses clonam macacos com tAi??cnica da ovelha Dolly

Autores afirmam que esse tipo de clonagem permitirA? pesquisas com populaAi??Ai??es de macacos “geneticamente uniformes”, ajudando no estudo de doenAi??as

Em 1996, a ovelhaAi??DollyAi??ficou conhecida por ser o primeiro animal clonado a partir de uma cAi??lula adulta, com uma tAi??cnica conhecida como transferA?ncia nuclear de cAi??lula somA?tica (SCNT, na sigla em inglA?s). Agora, mais de duas dAi??cadas depois, cientistas chineses utilizaram pela primeira vez a mesma tAi??cnica para produzir os primeirosAi??clonesAi??deAi??macacos.

Segundo os autores do estudo, publicado nesta quarta-feira, na revista Cell, esse tipo de clonagem em macacos permitirA? pesquisas com populaAi??Ai??es de animais geneticamente uniformes. Assim, serA? possAi??vel estudar uma doenAi??a genAi??tica, por exemplo, produzindo dois macacos idA?nticos, com uma modificaAi??A?o A?nica no gene de interesse. Assim, os animais clonados poderiam ser utilizados como modelos para pesquisas sobre doenAi??as cerebrais, metabA?licas, genAi??ticas, imunolA?gicas, ou celulares (como o cA?ncer), alAi??m de servirem para testes clAi??nicos de novas drogas.
