Stem Cells News and Research

Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Scientists identify new strategies used by Helicobacter pylori to target mitochondria

Helicobacter pylori is a bacterial pathogen that colonizes the stomach of approximately half of the world's population. Infection with H. pylori is acquired in childhood and lasts for decades.

New pluripotent stem cell technology provides insights into neuropsychiatric disorders

Studying the genetic code allows researchers to know whether some patients with neuropsychiatric disorders either have extra copies of the CHRNA7 gene or are missing copies. However, little was known about the functional consequences of this genetic imbalance in brain cells.

USC researchers propose rules for making ribs

Scientists from the USC Stem Cell lab of Francesca Mariani recently shared a recipe for ribs, and it doesn't even require barbecue sauce.

FSU researchers solve puzzle posed by family of rare premature aging disorders

New research from Florida State University is beginning to piece together the stubborn puzzle posed by a family of rare and debilitating premature aging disorders.

Intestinal epithelial stem cells may provide new insights into behavior of cancer cells

The lining of the intestines - the epithelium - does more than absorb nutrients from your lunch. It grows, shrinks, and adjusts the very makeup of its cells in response to whatever you just ate. And understanding that process might just give scientists new insights into the behavior of cancer cells.

New discovery could speed up production of cells for studying diseases

Scientists have made a key discovery that could speed up the production of cells in the lab for studying diseases such as multiple sclerosis and Parkinson's disease.

Newcastle scientists develop new technique that revolutionizes cell culture

A technique which revolutionizes cell culture by allowing the continuous production and collection of cells, has been developed by scientists at Newcastle University.

High levels of natural immune suppressor in leukemia patients linked to poor survival

Patients diagnosed with the most common form of leukemia who also have high levels of an enzyme known to suppress the immune system are most likely to die early, researchers say.

New study shows how SNO reaction may contribute to Parkinson's disease

A new study from The Scripps Research Institute is the first to show precisely how a process in nerve cells called the S-nitrosylation (SNO) reaction- which can be caused by aging, pesticides and pollution- may contribute to Parkinson's disease.

3D folding of DNA during cardiomyocyte differentiation provides vital epigenetic mechanisms, study says

A new study conducted at the University of Freiburg suggests that three-dimensional (3D) folding of the DNA reorganizes itself during differentiation of pluripotent stem cells to cardiomyocytes.

Research shows how HLF gene affects blood cell development

A research group at Lund University in Sweden has found that when the HLF (hepatic leukemia factor) gene -which is expressed in immature blood cells - does not shut down on time, we are unable to develop a functional long-term immune system. This could be a very early stage of leukemia.

Research suggests genome's spatial organization as important switch for defining cell types

During differentiation of pluripotent stem cells to cardiomyocytes, the three-dimensional folding of the DNA reorganizes itself. This reorganization of the DNA architecture precedes and defines important epigenetic patterns.

Researchers identify previously unknown breast cell types

A joint effort by breast cancer researchers and bioinformaticians has provided new insights into the molecular changes that drive breast development.

Scientists develop new method to study Creutzfeldt-Jakob disease in the lab

Scientists have developed a new system to study Creutzfeldt-Jakob disease in the laboratory, paving the way for research to find treatments for the fatal brain disorder.

Researcher awarded $1.5 million to study role of tumor necrosis factor in IBD

D. Brent Polk, MD, AGAF, an investigator at Children's Hospital Los Angeles, has been awarded $1.5 million by the National Institute of Diabetes and Digestive and Kidney Diseases of the NIH for the study of tumor necrosis factor (TNF) and its role in inflammatory bowel disease (IBD).

Selectively deleting stem cell factor promotes recovery after TBI in mice

UT Southwestern molecular biologists today report the unexpected finding that selectively deleting a stem cell transcription factor in adult mice promotes recovery after traumatic brain injury (TBI).

Researchers uncover mechanism that contributes to patterns of degeneration in AD

Alzheimer's disease (AD) is known to cause memory loss and cognitive decline, but other functions of the brain can remain intact.

Old World monkeys could hold key to stop progression of rheumatoid arthritis

In the quest for a new and more effective treatment for rheumatoid arthritis, researchers from the Keck School of Medicine of USC looked to a primate that mostly roams the land in Asia, the Middle East and Africa.

Drug used to prevent and treat malaria may also be effective for Zika virus

A new collaborative study led by researchers at Sanford Burnham Prebys Medical Discovery Institute and UC San Diego School of Medicine has found that a medication used to prevent and treat malaria may also be effective for Zika virus.

Brain astrocytes could play key role in pathogenesis of Alzheimer's disease

Astrocytes, the supporting cells of the brain, could play a significant role in the pathogenesis of Alzheimer's disease (AD), according to a new study from the University of Eastern Finland. This is the first time researchers discovered a direct association between astrocytes and AD. Published in Stem Cell Reports, the study investigated the brain cell function of familial AD patients by using stem cell technologies.
