Ⅱ.[2020·原创] 阅读理解
Today, people who need heart transplants(移植) must wait and hope to receive a donation. Even if they survive the wait, they might experience organ rejection (器官排异) and die. But this problem could be solved soon.
On April 15, 2019, scientists announced that they had created a human heart using 3-D printing. “This is the first time anyone anywhere has successfully engineered and printed an entire heart,” scientist Tal Dvir told Ha’aretz.
The heart has cells, blood vessels(血管), ven-tricles(心室) and chambers(心房), just like a real heart. But scientists still have more to figure out before they can start using the heart. For one thing, the new experimental organ is tiny, about half the size of your thumb. It also can’t pump(抽吸) blood, yet. It’s like a tiny airplane that has all of the right parts, but can’t fly.
Don’t be sad, though! This is still a major achievement. The World Health Organization(WHO) says more people die each year from heart diseases than any other cause of death.
Dvir and his team used a complicated(复杂的) process, turning human fat tissue(脂肪组织) into human heart tissue with stem cell(干细胞) technology. The tissue was then turned into “bio-ink” for the 3-D printer.
Ideally, each printed heart would use tissue taken from the person who needs it. In this way, the patients’ bodies will be less likely to reject the organ, making transplants much safer. In theory, the technique could be used to produce a new heart in just one day.
The team’s next step is to develop the technology further and to use it to print other human organs.
