There's been a potential breakthrough in making organs in the lab. Israeli researchers have 3D printed a heart, complete with muscle and blood vessels. But how long before it is ready for actual use? Not for a while, according to Dr. Max Gomez of CBS New York. Printing an organ is much more complicated than squirting a bunch of cells into the shape of a heart or kidney.That said, researchers at Tel Aviv University have taken a big step toward off-the-shelf organs. Video shows a living heart being printed out. The 3D printing includes not just heart cells, but blood vessels and other supporting structures. It's a small heart, about the size of a rabbit's. Not only are the cells alive, but all of the different cell types in the heart came from a single human donor."That's important because it prevents the possibility of rejection," said Dr. Anthony Atala of the Wake Forest Institute for Regenerative Medicine.Dr. Atala is a pioneer in 3D printing of organs and tissues. He … [Read more...] about Researchers claim they’ve 3D-printed artificial heart using patient’s cells
What makes stem cells different from other cells
1 A whole new world BIOLOGY IS A way of structuring matter at a molecular scale by slotting each atom into its needful place. It is a way of controlling flows of energy on every scale from that of the smallest living cell to that of the whole living planet. It is a way of growing order and surprise in a universe that in all other respects tends towards entropic stagnation. And it is a thicket of limits on how long lives can last and how much life can accomplish. Get our daily newsletter Upgrade your inbox and get our Daily Dispatch and Editor's Picks. It is also a way of packing 3,500 excited young people into the Hynes Convention Centre in Boston, Massachusetts. More than 300 teams from 42 countries took part in the annual International Genetically Engineered Machine (iGEM) competition there last October. By encouraging such teams to co-operate and compete in its Grand Jamboree, the iGEM foundation is hoping to create a framework for a synthetic-biology industry which combines … [Read more...] about The engineering of living organisms could soon start changing everything
Nearly 20 years ago, scientists stunned the world when they announced they had decoded the genes that make up a human being. They hoped to use that genetic blueprint to advance something called gene therapy which locates and fixes the genes responsible for different diseases. Now, a clinical trial at the National Institutes of Health is doing exactly that in an attempt to cure sickle cell anemia, a devastating genetic disease that kills hundreds of thousands of people around the world every year. For the past 15 months we've been following the scientists, and patients, who are ushering in a genetic revolution. Jennelle Stephenson: I'm excited. Ray Stephenson Today is the big day. It's the day after Christmas, 2017, and 27-year-old Jennelle Stephenson has come with her father and brother from Florida to the National Institutes of Health, just outside Washington, DC. Jennelle Stephenson: Good morning. Dr. John Tisdale: Good morning. She's one of a small group of patients to receive an … [Read more...] about Could gene therapy cure sickle cell anemia?

Father-of-two Scott Wallace (36) from Glengormley underwent the procedure last year and is urging others to become "a lifesaver in waiting". He signed up as a donor in 2012 with the charity DKMS. He explained: "As a child my cousin had always been ill before we realised he had blood cancer. "When I signed up as a donor it was because of a child of my wife's friend who needed a donation."
