Stem Cells News and Research

RSS

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.

Cells balance protein production and removal through passive adaptation

Every cell depends on proteins to function and stay healthy. These proteins are made inside the cell from amino acids but cannot simply accumulate inside the cell forever.

New grant supports research into drug-induced brain toxicity

Important FDA-approved drugs to treat HIV and cancer can save lives, but they come with their own risks. Some drugs used clinically are known to cause neurological side effects in up to half of patients, ranging from confusion and memory problems to permanent nerve damage.

Viral DNA elements help control early embryonic development

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ago, when viruses inserted their genetic material into our ancestors' genomes during infection.

Autophagy steers T cell fate during immune division

Researchers at the Max Delbrück Center have found that a cellular housekeeping mechanism called autophagy plays a major role in ensuring that T stem cells undergo normal cell division.

New tear gland organoids shed light on the biology of dry eye disease

An estimated 5-15% of people have problems with dry eyes, with symptoms including eye redness, stinging, or burning sensation, and eye fatigue. Dry eye disease (DED) occurs when the eyes' tear glands produce insufficient or poor-quality tears which can be due to allergy or autoimmune disease, hormonal changes, aging, etc.

New clinical trial offers hope for patients with advanced “dry” age-related macular degeneration

Age-related macular degeneration, the leading cause of vision loss and blindness for Americans 65 and older, is a progressive disease affecting central vision.

Hydrogel-based treatment achieves innervation and pulp-dentin regeneration

The dental pulp is susceptible to microbial infection, which often results in inflammation, necrosis, and defects in the pulp-dentin complex. Traditional treatment strategies suffer from multiple limitations and do not promote neural regeneration.

Combining stem cell therapy and BDNF enhancement to manage Parkinson’s disease

Parkinson's disease (PD) is an age-related, progressive, neurodegenerative condition, caused by loss of dopamine-producing neurons.

Hypertrophic chondrocytes play a crucial role in bone growth and repair

Normal, regulated growth of skeletal bones is a crucial part of the growth of mammals. This is a complex process involving the growth of cartilaginous cells or chondrocytes, their transformation into bone-building cells or osteoblasts, and the formation of new blood vessels to supply the newly formed bone tissue.

Engineering muscle stem cells for sustainable cultured meat production

The production of cultured meat depends on the isolation, expansion, and differentiation of animal stem cells into edible tissues. Muscle stem cells, or satellite cells, are central to this process due to their ability to regenerate and form muscle fibers.

UC Irvine receives funding for clinical trial of neural stem cell therapy for Huntington's disease

Leslie M. Thompson, Donald Bren Professor of psychiatry and human behavior as well as neurobiology and behavior at the University of California, Irvine, has received an $11,999,933 grant from the California Institute for Regenerative Medicine for an unprecedented clinical trial of a novel neural stem cell therapy for Huntington's disease.

Human heart organoids enable new therapies for atrial fibrillation

Though an estimated 60 million people around the world have atrial fibrillation, or A-fib, a type of irregular and often fast heartbeat, it's been at least 30 years since any new treatments have been developed.

Researchers identify chromatin accessibility changes driving stem cell transformation in MDS

Over the past few decades, advances in hematology have illuminated how a delicate balance between stem cell self-renewal and differentiation sustains healthy blood formation.

New findings show why the human intestine uniquely presents gluten to T cells

Human intestinal M cells function as dendritic cell-like antigen-presenting cells, displaying constitutive MHC-II activity and specialized machinery for processing gluten. Their ability to deamidate and present gliadin peptides positions them as key initiators of immune responses relevant to coeliac disease.

Study reveals how Ebola and Marburg viruses damage the human gut

Ebola (EBOV) and Marburg virus (MARV) are highly lethal viruses that cause severe disease in infected patients by extensively damaging the body.

Antibody therapy clears residual multiple myeloma in early trial

Treatment with an immune and cancer cell-targeting antibody therapy eradicates residual traces of the blood cell cancer multiple myeloma, according to interim results from a clinical trial conducted by researchers at Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine.

Nanoflower-treated stem cells deliver healthier mitochondria to stressed cells

This study shows that vacancy-engineered MoS₂ nanoflowers drive mitochondrial biogenesis in human mesenchymal stem cells by activating SIRT1–PGC-1α signaling and reducing oxidative stress. These treated cells transfer more functional mitochondria to injured recipient cells, restoring energy metabolism and redox balance in multiple in vitro models.

Timing of genetic mutation dictates childhood leukemia aggressiveness

A team of researchers at the Icahn School of Medicine at Mount Sinai has uncovered why children with the same leukemia-causing gene mutation can have dramatically different outcomes: it depends on when in development the mutation first occurs.

UCI MIND secures major funding for new Alzheimer's research facility

With a $50 million lead gift from the Quilter family and approximately $30 million in new commitments, the University of California, Irvine's Institute for Memory Impairments and Neurological Disorders will begin planning to build a state-of-the-art research and care facility to enhance its position as a global leader in Alzheimer's disease and related dementias research and patient care.

JAX wins $30 million contract to create computational "digital twins" of the human heart

Developing new drugs is one of the riskiest and most expensive endeavors in science. Today, The Jackson Laboratory (JAX) announced a bold initiative to improve that trajectory, powered by an up to $30 million contract from the Advanced Research Projects Agency for Health (ARPA-H) Computational ADME-Tox and Physiology Analysis for Safer Therapeutics (CATALYST) program.
