Heart failure patients who fit a specific profile can benefit from injection of stem cells delivered directly into their heart muscle, a new study finds.

Patients with mild or moderate heart failure who have high levels of inflammation responded well to the stem cell injections, and experienced a decline in their risk of heart attacks, strokes and heart-related death, clinical trial resul...

The sale of unproven and unapproved stem cell treatments has skyrocketed in the United States, according to a new five-year study.

The study found a fourfold jump since 2016 in the availability of the treatments, which claim to do everything from relieving pain to slowing aging.

People who use these treatments are needlessly spending thousands of dollars and could be putting their h...

New research in mice may provide clues to age-related hair loss in men and women.

Scientists found that as hair stem cells in mice age, they lose the stickiness that keeps them secured inside the hair follicle. This allows the stem cells to drift away from the follicle.

"The result is fewer and fewer stem cells in the hair follicle to produce hair," said study lead author Rui Yi, a ...

Nine of 10 patients with so-called "bubble boy" immune disease who received gene therapy about a decade ago are still disease-free, researchers report.

The gene therapy was developed at the University of California, Los Angeles (UCLA), to treat the rare and deadly immune system disorder formally known as adenosine deaminase--deficient severe combined immunodeficiency (ADA-SCID).

It'...

Cora Oakley is a rough-and-tumble 4-year-old who loves gymnastics and outdoor activities, particularly if it involves bouncing on a trampoline.

It's hard to tell from looking at her that she was born without an immune system. Kids with this condition can acquire dangerous, life-threatening infections from day-to-day activities as simple as going to school or playing with friends.

"I...

One of the most dangerous complications of diabetes is a foot ulcer that won't heal, but now a preliminary study finds that a type of stem cell found in body fat may be a powerful remedy for these severe foot wounds.

The study included 63 patients with non-healing diabetic foot ulcers who were given injections of cells from their own body fat. Over the next year, the treatment healed the ...

Combining stem cell transplants with cutting-edge immunotherapy prevents leukemia relapses in young people and improves their chances of survival, new research suggests.

Acute lymphoblastic leukemia is the most common childhood cancer.

This study included 50 patients (ages: 4 to 30) with acute lymphoblastic leukemia who received CAR T-cell therapy. The treatment genetically modifies...

Research into miscarriages, infertility and birth defects is now primed to undergo revolutionary advances, thanks to the creation in the lab of an early stage of human embryos by two separate international teams of scientists.

Both teams were able to use human cells to create artificial blastocysts, an early stage of conception that occurs a few days after egg fertilization but prior...

Spinal cord injuries can be devastating to the more than 17,000 Americans who suffer them each year. But many patients may have new reason for hope: Early research suggests infusions of stem cells could help them regain lost sensation and movement.

These improvements may occur within days or weeks of receiving the stem cell therapy, and can last at least six months, according to the small...

Stem cell transplants may have long-lasting benefits for some people with aggressive cases of multiple sclerosis, a new study suggests.

Italian researchers found that among 210 multiple sclerosis (MS) patients who received a stem cell transplant -- with cells from their own blood -- two-thirds saw no worsening in their disability 10 years out.

That included 71% of patients with rela...

A promising step toward using retinal cell transplants to treat blindness is reported in a new study.

Adult retinal stem cells from deceased human donors survived when they were transplanted into the eyes of non-human primates, according to the researchers.

The cells were taken from the retinal pigment epithelium (RPE). It is a layer of cells that supports and nourishes the retina, ...

Researchers say a new study may offer hope for future patients with glioblastoma, an aggressive brain cancer. It's the brain tumor that killed Senators John McCain and Ted Kennedy.

Investigators from the University of Toronto discovered that the healing process after a brain injury could spur tumor growth if new cells meant to replace those lost in the injury were derailed by mutations.

Stem cells derived from a baby's umbilical cord can help save the lives of the sickest COVID-19 patients, results from a small new clinical trial suggest.

Severely ill COVID patients who received two intravenous doses of stem cells three days apart were much more likely to survive and recover quickly, researchers found.

"The results are quite spectacular," said senior researcher Dr....

A pair of new gene therapies promise a potentially lasting cure for sickle cell disease by subtly altering the genetic information in patients' bone marrow cells, researchers report.

Both therapies work by switching on a gene that promotes production of fetal hemoglobin, said Dr. Lewis Hsu, chief medical officer of the Sickle Cell Disease Association of America.

Sickle cell dis...

In a first, scientists have treated a Parkinson's disease patient with his own skin cells -- repurposing them to become key brain cells that the disease kills off.

Two years after receiving the experimental treatment, the patient has had no adverse effects, his doctors report. His symptoms, meanwhile, have either stabilized or gotten somewhat better.

"The improvement has be...

Transplants of skin cells that were turned into light-sensing eye cells enabled blind mice to detect light, a new study says.

In previous research with lab animals, scientists have programmed stem cells created from blood or skin cells to become photoreceptors and transplanted them into the back of the eye.

Researchers said this study shows that it's possible to skip the ste...

One of the few bright spots in the COVID-19 pandemic has been the perception that children are mostly spared from its worst effects. But what about kids already at risk of contracting serious infections due to a compromised immune system? Do they have the same protection?

"One group we always worry about when it comes to viral illnesses is immunocompromised children," said Dr. Reggie...

People who develop Parkinson's disease at a younger age (before age 50) may have malfunctioning brain cells at birth, according to a study that also identified a drug that may help these patients.

At least 500,000 people in the United States are diagnosed with Parkinson's each year. Most are 60 or older at diagnosis, but about 10% are between 21 and 50.

Parkinson's is ...

The next time you tell your rebellious teenagers that their antics are giving you gray hair, know that the latest animal research seems to confirm your claim.

Scientists report they have pinpointed how stress causes gray hair in mice, and they said that their findings improve knowledge of how stress can affect the human body.

"Everyone has an anecdote to share about how stre...

It sounds scary, but the changes are only temporary: Researchers report that heart cells grown in space showed altered gene expression.

But just 10 days after being returned to Earth, the heart cells returned to normal.

Once stem cells grew into heart cells aboard the International Space Station, their exposure to microgravity changed the expression of thousands of genes.

There are significant racial disparities in treatment of U.S. patients with multiple myeloma, a new study shows.

Researchers reviewed nationwide data on 3,504 white, 858 black and 468 Hispanic patients treated from 2007 to 2013.

The average time between multiple myeloma diagnosis and start of treatment was 2.7 months for whites; 4.6 months for Hispanics; and 5.2 months for b...

Pregnant women should keep in mind that donating their umbilical cord blood could save lives, a clinical cell therapy expert says.

Cord blood is the blood collected from the umbilical cord and placenta after the birth of a healthy baby, said Fabio Triolo. He is director of the Cellular Therapy Core laboratories at University of Texas Health Science Center at Houston.

Cord bl...

Folks who get treatment from a stem cell clinic could be spending their money on what amounts to snake oil, a new study warns.

Doctors administering stem cells might have no expertise in the condition they're trying to treat, and the cells themselves might be derived from questionable or discredited sources -- if the treatment contains any stem cells at all.

"The stem cell treat...

Could wigs, weaves or transplants someday become a thing of the past? Scientists report they were able to grow hair with stem cells in animal studies.

So far the technique has only been tried on mice, and results may not be the same in humans. But researchers say they have been able to grow natural-looking hair through the skin using stem cells.

This could bring new hope t...

There's a good chance the doctor treating you at a stem cell clinic doesn't have any professional training related to your illness, researchers report.

Anesthesiologists, dermatologists, plastic surgeons, radiologists and family doctors are among a wide range of physicians overseeing treatments at U.S. stem cell clinics for complex neurological and orthopedic diseases, the study found...

Scientists have developed a way to grow live bone using a rib and a 3-D mold in animal studies, and they say their technique could offer a new way to treat severe head and facial injuries.

The technique was tested in sheep. First, the researchers made a rectangular defect in the animal's jaw. Then they printed out an implantable mold and spacer made of bone cement.

They atta...

Doctors say they have sent a second HIV patient into what might be permanent remission using a stem cell transplant.

The news comes a decade after the first case of a cure was reported.

Back in 2009, doctors published a report in the New England Journal of Medicine detailing the case of the "Berlin patient" -- an HIV-positive man who'd received a stem cell transplant ...

Scientists who used stem cells to grow functional kidneys in rats say their research could point the way to growing new kidneys for humans.

A shortage of donor kidneys means many people with kidney failure never get a transplant. In the United States alone, 95,000 people are waiting for a new kidney.

To address shortages of donor organs, scientists are trying to find ways to...

A stem cell transplant may help some people with multiple sclerosis (MS) when standard drugs fail, a new clinical trial finds.

The study focused on 110 patients with aggressive cases of MS: Their symptoms had flared up at least twice in the past year despite taking standard medication, and they'd already tried an average of three of those drugs.

Researchers randomly assigned...
