夏说英语新闻晨读 第411期:人工猪肺移植成功

 本期内容：

Scientists have successfully transplanted a bioengineered lung into a pig. To create a new lung, experts used a "scaffold" that provided structural¹ support and slowly built up the lung tissue around it, using cells from the pig that was due to get the transplant. This was done to prevent the lung being rejected by the pig's immune system.
