A study published last week in the journal Biofabrication describes a new technique to build replacements for damaged three dimensional human tissues. The researchers running the study are trying to make an eardrum. But their technique, if successful, might also one day create replacements for complex reproductive…
Using advanced techniques in tissue engineering and regenerative medicine, doctors in the U.S. are reporting their first successes with lab-grown penises. They've worked in rabbits, and now scientists say they're ready to begin testing the penises on humans.
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.
Yes, this man actually has a nose growing on his forehead. It's part of a cutting-edge transplant procedure, and doctors will eventually replace his damaged nose with the new, healthy organ.
A 5-oz beef patty assembled from thousands of teeny-tiny meat strips, cultured from the stem cells of a single cow, is to be served next week week in London. The price: £250,000, or about $385,000.
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.
Scientists at Harvard University have developed a cyborg-like tissue that can facilitate cell growth, while simultaneously measuring the ongoing activity and status of those cells. They did so by embedding a three-dimensional network of functional, biocompatible, nanoscale wires into engineered human tissues. The…
The prospect of lab-grown meat has intrigued both vegetarians and environmentalists for years. Humans eat about 240 billion kilograms of meat each year — a voracious demand for animal protein that has resulted in environmental degradation, cruelty to livestock, and the spread of dangerous diseases. And now, owing to…
In this video, released yesterday, you can watch what might be called the world's first cyborg lifeform. Called a medusoid, it's a completely engineered jellyfish that blends living and non-living parts — specifically, the creature is a thin layer of rat heart muscle cells grown on top of a layer of elastic…
For the first time ever, scientists have genetically transformed skin cells from heart failure patients into healthy, beating, "young" heart tissue. This is a fantastic achievement for the field of regenerative medicine.
There's no two ways about it: humans love meat. By 2030, it's estimated that the world's annual meat production will reach 376 million tons, up from 218 million tons in 1999.
There is no denying that growing an anal sphincter in a petri dish is hilarious. There is also no denying that nobody reading this would enjoy being without an anal sphincter, so it's good that there are back-ups being developed.
A new technique has been developed that uses spider silk to make human skin, suitable for skin grafts. And the world trembles. Find out why spider webs offer the best possible material to use for a skin replacement.
Mice are the first step in trying out new drugs that may one day help humans. The problem is that these rodents metabolize drugs in often a very different way than we do, meaning that much of the research in mice can't be applied to humans. Researchers from Stanford University may have found a way around this by…
Scientists have refined tissue repair techniques using stem cells to the point where they believe we might have pills that repair heart muscles in 10 years. Reports the BBC:
The cool trick about stem cells is that they're super adaptable, and can become any other sort of cell, right? So why not use a mass of stem cells to regenerate a limb? Or grow an extra one? Well, it looks like it's all a bit more complicated than that. According to new research on the self-regenerating Zebrafish,…
For the first time, scientists have coaxed a damaged heart to regrow healthy tissues on its own. They applied living "patches" to a heart, in what is a major breakthrough for people recovering from heart attacks.
A new cocktail that allows sodium ions to pour into cells makes tadpoles grow new tails. A similar one could be used to regenerate human spinal cords and lost limbs.
Hold off on the megadoses of antioxidant vitamins like C and E. A study by researchers at Cedars-Sinai Heart Institute shows that you can overdose on these health aids, and the result could be mutated stem cells that cause cancer.
A woman, blind for 9 years, can see again after doctors performed a rare surgery where her own tooth was inserted into eye. How does this procedure work?
