Cientista diz que desenvolveu cérebro humano em laboratório nos EUA

    Cientistas americanos conseguiram fazer crescer em um laboratório uma versão quase completa de um pequeno cérebro humano, algo que, segundo alegam, pode representar um avanço crucial para o tratamento de doenças neurológicas. Rene Anand, professor da Universidade Estadual de Ohio, conseguiu fazer crescer um cérebro com uma maturidade similar a de um feto de cinco semanas, informou a universidade.

    “Não apenas se parece com um cérebro em desenvolvimento, seus diversos tipos de células expressam quase todos os genes como um cérebro”, disse Anand. Com o tamanho de uma ervilha, o cérebro inclui múltiplos tipos de células, todas as principais regiões do cérebro e uma medula espinhal, mas carece de sistema vascular, explicou a universidade. O modelo foi desenvolvido a partir de células de pele humana e, segundo os cientistas, é o modelo de laboratório mais completo conhecido até agora. Anand apresentou seu trabalho nesta terça-feira (18) durante um evento militar sobre saúde na Flórida.

    Em geral, os avanços científicos importantes são divulgados em publicações especializadas, após avaliações de comitês independentes. Anand e um colega fundaram uma empresa em Ohio para comercializar o sistema de crescimento cerebral, segundo a universidade. “O poder deste modelo de cérebro é um bom presságio para a saúde humana porque nos dá opções melhores e mais relevantes para testar e desenvolver tratamentos que em roedores”, afirmou Anand em um comunicado.
