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.

Molecular map reveals how Down syndrome alters brain development

Scientists at UCLA have created one of the first cellular-resolution molecular maps detailing how Down syndrome alters human brain development before birth - a resource that resolves longstanding contradictions in the field and could lay the groundwork for future therapeutic strategies.

ISSCR urges NIH to continue support human embryonic stem cell research

The International Society for Stem Cell Research (ISSCR) has submitted a formal response to a Request for Information (RFI) issued by the National Institutes of Health (NIH) regarding its pause on new submissions to the NIH Human Embryonic Stem Cell (hESC) Registry and considerations to reduce reliance on hESCs in federally supported research.

New mouse model reveals primary trigger of rare muscle disorder

Myofibrillar myopathy type 6 (MFM6) is a rare genetic muscle disorder that leads to severe muscle weakness and a drastically shortened life expectancy due to a disruption in muscle protein regulation.

MSK scientists shed new light on a tumor's earliest moments

Scientists at Memorial Sloan Kettering Cancer Center (MSK) and their colleagues are shedding new light on a tumor's earliest moments - revealing how lung cells with cancer-causing mutations recruit accomplices from healthy surrounding tissue to pave the way for a tumor to develop.

New human cell model replicates key mechanisms of neurodegenerative diseases

Researchers at LMU have developed a human cell model that replicates key mechanisms of neurodegenerative diseases - with potential for novel therapies.

Stem cell model recreates early human embryo with yolk sac

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic manipulation.

AI chatbots give misleading health advice nearly half the time

Widespread inaccuracies in AI chatbot health responses pose public health risks, highlighting the urgent need for better oversight and cleaner training data.

Brain organoids may guide Alzheimer’s diagnosis and treatment

Scientists from Johns Hopkins Medicine report new evidence that clusters of brain tissue derived from the cells of patients with Alzheimer's disease may be used to evaluate how certain patients with the neurodegenerative condition may respond to drugs commonly prescribed to treat psychiatric symptoms of the disorder.

New gene target offers hope for fatal infant cardiomyopathy

Researchers from the Keck School of Medicine of USC have made an important advance toward understanding-and potentially treating-a rare cardiomyopathy (heart muscle disease) that is present from birth.

Study finds popular AI chatbots often give problematic health advice

Researchers audited five popular public-facing AI chatbots across 250 health prompts and found that 49.6% of responses were problematic, with especially weak performance on open-ended questions and in nutrition and athletic performance. The study also found poor citation quality, difficult readability, and very few refusals to answer, raising concerns about the reliability of chatbots for everyday health information.

Researchers discover how stress signals weaken the aging immune system

As we age, our ability to maintain healthy blood and a strong immune system gradually declines, largely because hematopoietic stem cells (HSCs), the cells responsible for producing all blood cell types, begin to lose their effectiveness. Normally, HSCs can both self-renew and generate a balanced mix of blood cells, but over time they produce fewer new cells, favor certain cells such as myeloid cells over lymphoid cells, and struggle to support a robust immune response.

Popular chatbots often provide inaccurate and incomplete medical information

A substantial amount of medical information provided by 5 popular chatbots is inaccurate and incomplete, with half of the answers to clear evidence based questions "somewhat" or "highly" problematic, show the results of a study published in the open access journal BMJ Open.

Aston University bioscientist receives £125,000 to investigate genetic reasons for neurodegeneration

Aston University bioscientist Dr John Reynolds has won a £125,000 Springboard grant from the Academy of Medical Sciences (AMS) for research into neurodegeneration caused by a rare genetic disease.

Common osteoporosis drugs could slow or halt aneurysm progression

Aortic aneurysms are characterized by abnormal enlargement of the aorta, the primary artery responsible for carrying blood from the heart. Rupture often leads to sudden death, and currently, no effective drug therapies are available to halt disease progression.

Targeting senescent fat cells provides new hope for ovarian cancer

Ovarian cancer is the most lethal malignancy of the female reproductive system. Due to its insidious early symptoms and the absence of specific screening modalities, approximately 70% of patients are diagnosed at an advanced stage.

Microneedle nanoparticle platform improves lymphatic imaging with high resolution

The lymphatic system plays a critical role in pathological conditions such as lymphedema and chronic inflammation to tumor metastasis, venous insufficiency, and impaired wound healing, making accurate evaluation of its structure and function increasingly important.

Metformin protects neurons after brain injury by restoring mitochondrial health

TBI remains a major cause of death and long-term neurological disability worldwide, yet effective treatments for secondary injury are still lacking.

Protein complex cohesin found essential for guiding cell identity decisions

Temporarily disabling a protein complex that organizes DNA into loops inside the cell's nucleus drastically disrupted the three-dimensional structure of the genome, but surprisingly most genes continued to function as usual, Weill Cornell Medicine researchers found.

Damon Runyon supports young scientists driving cancer research innovation

The Damon Runyon Cancer Research Foundation has named 13 new Damon Runyon Fellows, exceptional postdoctoral scientists conducting basic and translational cancer research in the laboratories of leading senior investigators.

Pseudogene lncRNAs regulate cancer stem cell behavior and signaling

Cancer stem cells (CSCs), a critical subpopulation within tumors, drive cancer initiation, progression, metastasis, relapse, and resistance to therapy due to their innate capacity for self-renewal and differentiation.
