Salk scientists propose new molecular criteria for generating naïve stem cells

Salk scientists and colleagues have proposed new molecular criteria for judging just how close any line of laboratory-generated stem cells comes to mimicking embryonic cells seen in the very earliest stages of human development, known as naïve stem cells.

Researches create mini-brain model of idiopathic ASD characterized by early neuronal overgrowth

The vast majority of cases of autism spectrum disorder (ASD) are idiopathic - the cause is unknown.

Scientists use stem cell techniques to unravel biology of autism

The brains of some people with autism spectrum disorder grow faster than usual early on in life, often before diagnosis.

Researchers develop in vitro model system for investigating etiology of NAFLD

Researchers from the Institute for Stem Cell Research and Regenerative Medicine at the University Clinic of Düsseldorf have established an in vitro model system for investigating nonalcoholic fatty liver disease (NAFLD).

Researchers uncover new clues about role of glucosamine in early embryonic development

Most pregnant women with well-controlled diabetes give birth to healthy children. But their babies run much higher risks of birth defects than babies born to women without diabetes, because very early in embryonic development, the babies are exposed to higher levels of glucose in maternal blood.

Understanding cancer resistance in mole-rats may help advance human treatment in future

Naked mole-rats (NMR) are the longest-living rodent species and exhibit 'extraordinary' resistance to cancer. Mole-rats live up to 30 years, 10 times longer than mice, and captured colonies almost never show any type of cancer.

New technique may help replace brain cells, restore memory

Although brains—even adult brains—are far more malleable than we used to think, they are eventually subject to age-related illnesses, like dementia, and loss of cognitive function.

Study shows similarity between embryonic and reprogrammed stem cells

Stem cells are specialized undifferentiated cells that can divide and have the remarkable potential to develop into many different cell types in the body during early life and growth.

About 30% of iPSCs not safe for clinical use, report multi-institutional researchers

As the promise of using regenerative stem cell therapies draws closer, a consortium of biomedical scientists reports about 30 percent of induced pluripotent stem cells they analyzed from 10 research institutions were genetically unstable and not safe for clinical use.

Multiple cell and gene therapies can enhance cardiac function in mice modeled with MI

Researchers at the University of Utah compared the therapeutic potential of umbilical cord-derived sub-epithelial cells (UC-SECs), bone marrow-derived mesenchymal stem cells (BM-MSCs) and induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) -- all derived from human tissue -- along with genes (S100a1 and SDF-1a) and growth factor (VEGF165) to evaluate how injected biologics might enhance cardiac function in mice modeled with myocardial infarction (MI; commonly referred to as heart attack).

WPI receives patent for novel method of reprogramming human skin cells

Cell therapies for a range of serious conditions, including heart attacks, diabetes, and traumatic injuries, will be accelerated by research at Worcester Polytechnic Institute that yielded a newly patented method of converting human skin cells into engines of wound healing and tissue regeneration.

New experimental model may predict eventual cardiac phenotype in pediatric patients

An experimental model uses genetics-guided biomechanics and patient-derived stem cells to predict what type of inherited heart defect a child will develop, according to authors of a new study in the journal Cell.

ISSCR releases updated guidelines for stem cell research, development of new therapies

The International Society for Stem Cell Research, the world's largest professional organization of stem cell scientists, today released newly updated guidelines for stem cell research and the development of new clinical therapies.

Study suggests ways of minimizing DNA folding errors

Induced pluripotent stem cells hold promise for regenerative medicine because they can, in theory, turn into any type of tissue and because they are made from a patient's own adult cells, guaranteeing compatibility. However, the technique that turns adult cells into these iPS cells is not foolproof; after reverting to their pluripotent state, these cells don't always correctly differentiate back into adult cells.

Researchers safely transplant stem cells from patient's skin to the eye to restore vision

Researchers have safely transplanted stem cells derived from a patient's skin to the back of the eye in an effort to restore vision. The research is being presented at the 2016 Annual Meeting of the Association for Research in Vision and Ophthalmology this week in Seattle, Wash.

Scientists reprogram mature blood cells from mice into blood-forming HSCs

Researchers at Boston Children's Hospital have reprogrammed mature blood cells from mice into blood-forming hematopoietic stem cells (HSCs), using a cocktail of eight genetic switches called transcription factors. The reprogrammed cells, which the researchers have dubbed induced HSCs (iHSCs), have the functional hallmarks of HSCs, are able to self-renew like HSCs, and can give rise to all of the cellular components of the blood like HSCs.

New article reviews ability of different stem cells to help restore function after spinal cord injuries

Stem cell therapy is a rapidly evolving and promising treatment for spinal-cord injuries. According to a new literature review, published in the April issue of the Journal of the American Academy of Orthopedic Surgeons, different types of stem cells vary in their ability to help restore function, and an ideal treatment protocol remains unclear pending further clinical research.

Under-expressed miR-9 gene may contribute to schizophrenia risk

By turning skin cells into brain neurons, researchers at the Icahn School of Medicine at Mount Sinai have identified that certain tiny molecules aiding in gene expression, known as microRNAs (miRNAs), are under-expressed in the brains of the 14 schizophrenia patients they studied. Their findings, published online today in the journal Cell Reports, show that one of these molecules, a miRNA known as miR-9, is a risk factor that controls the activity of hundreds of genes.

Scientists identify critical biological factor for transforming adult somatic cells into stem cells

In a new Cell Reports paper, a team led by John P. Cooke, M.D., Ph.D., of the Houston Methodist Research Institute, has identified and characterized a biological factor critical to the transformation of adult somatic cells (cells that are not sperm or egg cells) into stem cells.
