Citando:
"The company and its collaborators published their work in the journal Science, where they explain how they created the PERV-less piglets.

Using a genome-editing tool named CRISPR, the researchers created PERV-free embryos, implanted them into surrogate female pigs, which gave birth to piglets without the retrovirus. 

The piglets are now four-and-a-half months old and will be monitored for any long-term effects. "

(...)
"But the fear of transmitting PERVs to humans was, among other hurdles, blocking progress toward successful xenotransplantation, making the eGenesis find an important one."

Futuro: curar feridas e renovar órgãos?

"“By using our novel nanochip technology, injured or compromised organs can be replaced,” said Chandan Sen, from the Ohio State University, who co-led the study. “We have shown that skin is a fertile land where we can grow the elements of any organ that is declining.”"
