Cientistas da USP conseguiram transformar c\u00e9lulas-tronco presentes na gordura em c\u00e9lulas musculares humanas. O experimento foi feito no corpo de camundongos.<\/div>\n

Cientistas da Universidade de S\u00e3o Paulo (USP) fizeram novas descobertas sobre o poder das c\u00e9lulas-tronco. Testes em laborat\u00f3rio tiveram resultados surpreendentes em rela\u00e7\u00e3o \u00e0 distrofia muscular.<\/p>\n

A mat\u00e9ria-prima da descoberta veio daqueles pneuzinhos indesejados e eliminados com lipoaspira\u00e7\u00e3o em cl\u00ednicas de cirurgia pl\u00e1stica. A gordurinha posta de lado virou material de pesquisa nas m\u00e3os destas cientistas. Material rico em c\u00e9lulas-tronco adultas, que t\u00eam a fun\u00e7\u00e3o de fazer pequenos reparos em determinadas partes do corpo.<\/p>\n

Estas s\u00e3o capazes de se transformar em c\u00e9lulas \u00f3sseas, de cartilagens e tamb\u00e9m em c\u00e9lulas musculares. Mas o mecanismo que dispara a ordem de transforma\u00e7\u00e3o destas c\u00e9lulas dentro do corpo ainda \u00e9 desconhecido.<\/p>\n

Depois de quase um ano de tentativas, os cientistas conseguiram transformar as c\u00e9lulas-tronco da gordura em c\u00e9lulas musculares humanas no corpo dos camundongos. E junto com elas, veio tamb\u00e9m um resultado impressionante.<\/p>\n

Os camundongos tinham distrofia muscular, uma doen\u00e7a gen\u00e9tica grave que afeta a for\u00e7a dos m\u00fasculos aos poucos e que ainda n\u00e3o tem cura. Pois veja o que aconteceu: um camundongo n\u00e3o recebeu c\u00e9lulas-tronco. Por causa da distrofia muscular, ele n\u00e3o consegue se segurar no arame e cai.<\/p>\n

J\u00e1 o camundongo que recebeu as c\u00e9lulas-tronco de gordura parece que ter\u00e1 o mesmo destino. Mas, de repente, ele reage e se agarra com firmeza ao arame. As c\u00e9lulas de gordura viraram m\u00fasculos que funcionam.<\/p>\n

Para Mayana Zatz, coordenadora da pesquisa, a descoberta \u00e9 um passo importante na dire\u00e7\u00e3o do tratamento da distrofia muscular. \u201cA chave \u00e9 a gente descobrir e poder controlar totalmente esse processo. S\u00f3 a\u00ed \u00e9 que a gente vai ficar seguro de injetar. Eu acho que se essas experi\u00eancias que estamos testando agora derem certo, a gente pode pensar talvez em 2 ou 3 anos come\u00e7ar ensaios cl\u00ednicos em pessoas\u201d, acredita Zatz, do Centro de Estudos do Genoma da USP.<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"
