Scientists Create Blood From Human Skin

It could have huge implications for transplants, transfusions

(Newser) - Researchers from McMaster University in Canada have created blood from tiny pieces of skin in a development hailed as a major breakthrough. Why the big deal? Because the blood created is genetically identical to that of the skin's donor, meaning there's no chance of rejection. Not only that, experiments have...

Stem Cells Return Sight to 76-Year-Old

Woman to see great-grandson for first time

(Newser) - Stem cell treatment gave the gift of sight back to a 76-year-old British grandmother, putting her closer to her goal of seeing her 2-year-old great grandson for the first time, the Daily Mail reports. In an attempt to treat giant cell arteritis, the disease that took her sight in February...

Scientists Grow Human Livers in Lab

Miniature versions created with stem cells

(Newser) - Scientists have grown human livers with stem cells, the BBC reports. The downside is they're really small, about the size of walnuts, and it will take lots more research and probably at least five years before the development is more than just a joke to forward to heavy-drinking friends. "...

First US Stem Cell Trials Begin

Paralyzed patient injected with embryonic cells

(Newser) - American scientists have begun testing embryonic stem cells on a patient for the first time. The groundbreaking, federally-approved clinical trial involves injecting millions of the cells into a patient who suffered paralysis after a recent spinal cord injury, reports Reuters . Scientists hope the stem cells will regenerate nerves in the...

Appeals Court Temporarily Allows Stem Cell Funding

It will continue as case proceeds

(Newser) - A federal appeals court today permitted US government funding of stem cell research to proceed for now, while it considers a judge's ruling that had temporarily shut off the funds. The government is asking the appeals court in Washington to strike down a preliminary order by US District Judge Royce...

Nervous Scientists to Test Stem Cells on Humans

Less-than-positive results could spell disaster

(Newser) - Scientists are preparing the first human tests of stem cell treatments—and they're nervous about it. They plan to inject cells into patients with spinal cord injuries and progressive blindness, a move that, based on animal trials, should improve the patients' condition. But those involved still fear anything less than...

Judge Blocks Stem Cell Research Funding

Ban on using federal funds for embryonic research reinstated

(Newser) - President Obama's executive order expanding embryonic stem cell research has been blocked by a district judge who says it violates a ban on federal money being used to destroy embryos. US District Judge Royce Lamberth granted an injunction to stop federal funding of the research, a move that deals a...

Moms Donate Umbilical Cord Blood With New Kits

Pilot program gets it into public donor banks

(Newser) - A new movement is afoot to save and store potentially life-saving umbilical cord blood and make it available to the public, Time reports. Under a pilot program in Texas and North Carolina, new moms bring a kit to the hospital that doctors use to collect the blood and send it...

Stem Cells Reverse Blindness

Sight restored to people blinded by chemical burns

(Newser) - Stem cell transplants have helped dozens of people blinded by chemical burns to see again, Italian researchers say. Doctors used stem cells from undamaged parts of the patients' eyes to replace the damaged cornea. The procedure resulted in a successful transplant roughly 75% of the time. One man who badly...

Scientists Create Brain Cells From Skin Cells

Stanford breakthrough in mice skips stem cell stage

(Newser) - In what's being heralded as "a huge leap forward," Stanford researchers have successfully turned mouse skin cells into fully functioning brain cells. The process, which took less than a week, upends thinking on how cells develop specialized roles, and could help minimize the controversial role of embryonic stem...

Cord Blood Breakthrough Offers Leukemia Hope

Multiplying umbilical stem cells could overcome need for donor matching

(Newser) - A pioneering technique for multiplying umbilical cord cells has placed the long-elusive "holy grail" of leukemia research in sight, offering new hope for bone marrow transplant recipients. Researchers have manipulated a "signaling pathway" in umbilical cord cells to create more stem cells—thus overcoming the longstanding problem of...

Blindness Cure Could Be 1st Human Stem Cell Trial

Biotech firm aims to reverse macular degeneration

(Newser) - The first-ever clinical trials of stem cell treatment of humans could be under way early next year if a Massachusetts biotech firm wins FDA approval. Advanced Cell Technology yesterday applied for a license to use embryonic stem cells left over from IVF treatment, to aid people suffering from a rare...

Leftover Fat From Lipos Is 'Liquid Gold' for Stem Cells

Siphoned off fat better than skin for producing embyo-free stem cells

(Newser) - Blubber may be the next big thing in stem cell research. Stanford scientists have found that leftover liposuction fat contains cells that can be changed into induced pluripotent stem cells—a type that doesn't require the use of an embryo, the San Jose Mercury News reports. Until now, scientists have...

Study May Yield Better Cancer Drugs, Less Chemo

(Newser) - A breakthrough with cancer stem cells may lead to more potent drugs—ones that pair with chemotherapy in the sort of drug cocktail used against AIDS, reports the New York Times. If borne out, the development—in which researchers figured out how to screen for chemicals that attack only cancerous...

Scientists Retract Paper Touting Sperm From Stem Cells

But say attribution, not science itself, at issue

(Newser) - A paper by British scientists on the creation of synthetic human sperm had to be retracted from the journal Stem Cell and Development, AFP reports. The paper, which reported the revolutionary creation of sperm from stem cells, included text written by another scientist, who was not credited. The retraction is...

Scientists Breed Mice From Stem Cell Alternative

Researchers turn adult, not embryonic, skin cells into stem cells

(Newser) - Scientists in China have created mice using stem cells made from modified skin cells—hinting at an alternative to embryonic stem cells, the Washington Post reports. Separate teams used viruses to manipulate genes that caused mice skin cells to regress back into induced pluripotent stem cells—which, within a placenta...

'Synthetic Sperm' Grown From Stem Cells

(Newser) - British scientists announced they have created synthetic human sperm for the first time, the Guardian reports. The sperm—grown in a lab from stem cells—swim, have tails, and exhibit many of the same biological characteristics of real sperm, according to researchers. They believe the breakthrough could lead to a...

Scientists Find 'Master' Cells For Human Heart

Stem cells can mature into three different kinds of heart tissue

(Newser) - Researchers have found a cell that can become three different kinds of heart tissue, the Boston Globe reports. Harvard scientists hope that such “master” heart cells can be used to grow tissue so that researchers can perform experiments or test medications on human heart tissue, instead of animal substitutes.

Researchers Extract Stem Cells From Placentas

Effective harvesting procedure involves no risk to mother, child

(Newser) - Scientists have found an effective way to extract stem cells from placentas, where they’re abundant, after babies are born, the Guardian reports. Placentas contain up to five times as many of the key cells as cord blood, which has become a common source, and they may be more primitive,...

Untested Stem-Cell Treatments Lure Americans Abroad

FDA says they're untested, unsafe

(Newser) - Dozens, perhaps hundreds, of Americans have defied federal warnings against seeking untested—and often expensive—stem-cell therapy abroad, CNN reports. Though they lack scientific backing, such treatments for terminal diseases are popular in China, where the parents of one 8-year-old seek to treat her spinal muscular atrophy. “We are...
