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.
Almost all the cells in your body have two sets of 23 chromosomes, for a total of 46 chromosomes. These are diploid cells. Your sperm or your egg cells, called haploid cells, only have 23 chromosomes. For the first time, scientists have made human stem cells with haploid cells. This could lead to a lot of important…
Scientists have used stem cells to cure blindness in rabbits—which could be incredible news for visually impaired people.
Scientists strongly suspect a link between Zika and microcephaly, a disorder that causes abnormally small heads in newborns, but they’re not entirely sure. Now, a team of researchers may have figured out how this mosquito-borne virus attacks the developing brains of fetuses—and wow, is it nasty.
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.
We’re one step closer to being able to regrow a lost tooth, thanks to a new study showing it’s possible to grow multiple teeth from a single root. These teeth can then be implanted to become fully functional. Thus far it has only been tested in rats, but it could lead to a potential revolution in human dental care.
Two research teams in the last two months have published studies on kidney structures grown from stem cells, which might be a step toward personalized replacement organs grown from patients’ own cells.
You are looking at freshly-made human neurons, or brain cells. But they used to be common skin cells. And their existence could change how we treat Alzheimers.
In 2013, the world’s first lab-grown burger was unveiled to the world. It carried a $330,000 price tag, and apparently, it wasn’t all that tasty. But the scientists behind the idea have been hard at work, and artificial meat that’s both cost-effective and palatable may arrive sooner than we think.
Cancer-curing Cylon baby blood may still be a fantasy, but with the next two years, two human volunteers will be receiving the very first blood transplants manufactured in a lab, the British National Health Service announced last week.
Yep, you heard that one correctly. In what could be a major step forward for personalized medicine, researchers have perfected a technique for growing miniature balls of cortical tissue—the key working tissue in the human brain—in a dish.
Back in 2006, when controversy over embryonic stem cell funding was still raging, a piece of research came along that would make the debate essentially obsolete: normal adult cells can actually be reprogrammed into stem cells. No embryos necessary. The technique went on to win its inventor the Nobel Prize. And now,…
Inside each of our hard, calcified teeth is a small population of living stem cells that can differentiate into many types of tissue. The origin of those stem cells has long been unknown, but scientists may now have a completely surprising answer: Cells of the nervous system can migrate into the middle of a tooth and…
Remember a few months ago when the world stared slack-jawed at the scientist who turned blood cells into stem cells in a matter of minutes? This miraculous breakthrough could change medicine as we know it. Too bad it wasn't true. The study has now been officially retracted.
A team of researchers from the University of Virginia just made scientific history: They figured out how to turn stem cells into full blown fish embryos. In other words, scientists can now control embryonic development, a key to being able to grow organs and even entire organism from stem cells.
This is wild. Chasing the elusive dream of curing paralysis, a team of scientists used stem cells and optogenetics to circumvent the central motor system of lab mice whose nerves had been cut. This enabled them to blast individual motor neurons with a laser, triggering movement in the legs of the mice.
