By leveraging the regenerative powers of migraine medication, researchers at Tufts University have restored the vision of blind tadpoles after grafting eyes to their tails. Sounds bizarre, but a similar technique could one day be used on humans.
An unproven stem cell therapy conducted by a Florida clinic has blinded three patients in an apparent clinical trial gone horribly wrong. The incident showcases the extent to which unscrupulous clinics will take advantage of desperate patients—and how the lack of government oversight contributes to the problem.
Using stem cells, Japanese scientists have grown artificial skin that contains sweat glands and hair follicles. These highly realistic skin patches could eventually be used to treat burn victims and replace animals in the testing of chemicals.
Scientists from China have made history by taking a cell that’s not a sperm cell and then used it to create a live animal. A similar technique could be used one day to treat infertility in humans.
Scientists have developed an innovative 3D bioprinter capable of generating replacement tissue that’s strong enough to withstand transplantation. To show its power, the scientists printed a jaw bone, muscle, and cartilage structures, as well as a stunningly accurate human ear.
Researchers at Johns Hopkins Bloomberg School of Public Health have produced tiny brains made of human neurons and cells. These mini-brains could radically change how drugs are tested, replacing the many animals currently being used for neurological scientific research.
People with type 1 diabetes have to inject insulin daily, and it often results in pain, redness, swelling, and itching at the injection site. But this could soon be a thing of the past, thanks to a new breakthrough that takes us one step closer to a functional cure for type 1 diabetes.
Researchers in Germany have have grown the innermost layer of human fallopian tubes in a lab. The new technique is offering fresh insights into this essential component of the female reproductive system, while also hinting at potential new directions for the treatment of various reproductive disorders.
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.
After decades of work, a team of doctors say they've successfully engineered vaginas that have been implanted and grown in women. The vaginas were grown in a lab from the female patients' own cells and later transferred to their bodies, where they formed into normal vaginas. The breakthrough bears some huge…
