In a breakthrough that could lead to printable organs and an enhanced understanding of human physiology, researchers from Lawrence Livermore National Labs have 3D-printed functional blood vessels that look and function like the real thing.
The U.S. National Institutes of Health has stopped funding experiments in which human stem cells are transplanted into the embryo of an animal. Now, a group of researchers from Stanford University are speaking out, claiming that the restrictions are holding back important medical research—and that the NIH’s reasons…
For years, biologists have sought to understand how the genes of planarians, a group of free-living flatworms, direct growth in specific body parts. An artificial intelligence tasked with the problem appears to have cracked the code, a breakthrough that demonstrates the incredible potential for “robot science.”
The waiting list for organ transplants is growing at an alarming rate while the number of potential organ donors has failed to keep pace. Encouragingly, scientists are working several high-tech solutions in the field of regenerative medicine. We spoke to the experts to learn how organ shortages will soon become a…
Growing nerve tissue and organs is a sci-fi dream — but one that's poised to become a reality. Here's the remarkable story of a pioneering researcher who has actually figured out how to grow eyes and brain cells.
Two genetic programs have been discovered that turn stem cells into blood. The method, which mirrors the way blood is produced in the body, allows researchers to make both white and red blood cells. Encouragingly, the researchers produced 30 million blood cells for every million stem cells.
A German museum is exhibiting a 3D-printed copy of Dutch artist Vincent Van Gogh's ear grown from the genetic material of a distant relative.
In a recent experiment, mice with MS-like symptoms were able to walk and run again just two weeks after being injected with human neural stem cells. Even the researchers were unprepared for these incredible results. Though we're still far from a cure, it's a remarkable finding that hints at similar therapies for…
A few years ago, scientists from Stanford discovered that it's possible to reverse cognitive decline in old mice by injecting them with the blood of the young. Now, researchers have isolated the mechanism responsible for this rejuvenation — and it's a protein that's found in humans as well.
Scientists from South Korea have devised a technique for cloning adult stem cells that doesn't involve the destruction of human embryos. The resulting stem cells, which are highly personalized, could be used to treat illnesses such as heart disease and blindness — but the technique could also be used to clone adults.
Four women born with abnormal or missing vaginas were recently implanted with lab-grown replacements created from their own cells. All four women are now sexually active and report normal vaginal function.
For the first time ever, biologists have regenerated an organ in a living animal. They did so by manipulating a single protein in elderly mice that makes their bodies rebuild their thymuses, an organ of the immune system. It's the first time an organ has been repaired with a chemical trigger and not via stem cell…
A potential Nobel-winning stem-cell study is now under investigation for irregularities. Haruko Obokata rocked the science world last month by showing how stem-cells could be reprogrammed by an acid bath. Japan's RIKEN institute has now launched an inquiry following allegations of duplicate images and numerous failed…
Swiss researchers have achieved a major breakthrough in the development of bioengineered skin. The new grafts, which are about to undergo clinical trials, work a lot like the real thing — because they actually contain functioning blood vessels and lymph capillaries.
Michael Levin is a regenerative and developmental biologist at Tufts University in Massachusetts. He has spent most of his career studying how electrical signals travel between cells in the body. Now, he thinks we could use those signals to program our cells to regrow arms, legs, and even faces.
In a major scientific first, a team of developmental biologists has built a functional mouse heart from human tissues. The results herald a future where specific patches of heart muscle – or even the whole organ – could be grown for transplantation.
A new study shows that stem cells extracted from urine can be turned into rudimentary tooth-like structures. Oh, and the researchers did so by growing the teeth inside the kidneys of mice.
Two year-old Hannah Warren passed away this past Saturday at the Children’s Hospital of Illinois. Born without a trachea, she was the youngest recipient of a bioengineered organ — one that was grown from her very own stem cells. She will be remembered as a pioneer in regenerative medicine.
Two decades is not a lot in the grand scheme of things, but owing to accelerating change we can expect to see the emergence of some fairly disruptive technological innovations in the coming years. Here are 10 mindblowingly futuristic technologies that should appear by the 2030s.
The day is fast approaching when scientists will finally be able to reconstruct a person's heart from a clump of cells and a simple scaffold. We're not there yet, but this video will show you how it's done.
