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.

Phase III clinical study of regenerative therapy for treating damaged cartilage has started

A group of researchers at Osaka University developed a synthetic tissue using synovium-derived mesenchymal stem cells (MSCs) for treating damaged cartilage, which had previously been incurable and had no effective therapies.

Study reveals a loophole in treatment of chronic lymphocytic leukemia

A team of researchers in Italy and Austria has determined that a drug approved to treat chronic lymphocytic leukemia (CLL) may be less effective in a particular subset of patients.

Study illustrates the role of alcohol in causing damage to DNA and increased cancer risk

A new study conducted by a group of researchers at MRC Laboratory of Molecular Biology, Cambridge revealed the significant role of alcohol in causing damage to DNA in stem cells and thereby increasing cancer risks. The study was funded by Cancer Research UK and the results were published in Nature.

Scientists show how alcohol exposure leads to permanent genetic damage

Scientists have shown how alcohol damages DNA in stem cells, helping to explain why drinking increases your risk of cancer, according to research part-funded by Cancer Research UK and published in Nature today (Wednesday).

Genetic labeling helps researchers track behavior of blood cells

By tagging bone marrow cells of mice with a genetic label, or barcode, researchers were able to track and describe the family tree of individual blood cells as they form in their natural environment.

Researchers grow hairy skin using mouse stem cells

Indiana University School of Medicine researchers have cultured the first lab-grown skin tissue complete with hair follicles.

Spider's web inspires new device that could revolutionize management of type 1 diabetes

For the more than 1 million Americans who live with type 1 diabetes, daily insulin injections are literally a matter of life and death. And while there is no cure, a Cornell University-led research team has developed a device that could revolutionize management of the disease.

Bioengineers reveal how to recreate complex folded shapes from living tissue

Many of the complex folded shapes that form mammalian tissues can be recreated with very simple instructions, UC San Francisco bioengineers report December 28 in the journal Developmental Cell.

Gene therapy with CAR T-cells could create long-term immunity from HIV

Through gene therapy, researchers engineered blood-forming stem cells (hematopoietic stem/progenitor cells, or HSPCs) to carry chimeric antigen receptor (CAR) genes to make cells that can detect and destroy HIV-infected cells.

Study highlights pernicious effect of obesity on blood-making stem cells

New research published in the Journal of Experimental Medicine highlights the pernicious effect of obesity on the long-term health of blood-making stem cells (hematopoietic stem cells).

New approach to sticking bio-ink droplets together enables 3D printing of complex tissues

Printed replacement human body parts might seem like science fiction, but this technology is rapidly becoming a reality with the potential to greatly contribute to regenerative medicine. Before any real applications, "bioprinting" still faces many technical challenges.

Researchers find progenitor cells for all the heart's components, except right ventricle

Progenitor cells - undifferentiated cells that later become specified - for all the heart's components, except for the right ventricle, have been found by Hiroshima University researchers and detailed in a paper published in Nature Communications.

Researchers sequence salamander genome to reveal unique features of regeneration

Researchers at Karolinska Institutet in Sweden have managed to sequence the giant genome of a salamander, the Iberian ribbed newt, which is a full six times greater than the human genome.

Scientists elucidate why exercise slows progression of Parkinson's disease

While vigorous exercise on a treadmill has been shown to slow the progression of Parkinson's disease in patients, the molecular reasons behind it have remained a mystery.

Salk scientists find simpler way to derive functioning cardiac cells from stem cells

The process by which embryonic stem cells develop into heart cells is a complex process involving the precisely timed activation of several molecular pathways and at least 200 genes.

Multifunctional protein also plays role in development of blood cells

Like an actor who excels at both comedy and drama, proteins also can play multiple roles. Uncovering these varied talents can teach researchers more about the inner workings of cells.

Loss of specific protein makes breast cancers more aggressive, resistant to chemotherapy

Researchers in Italy have discovered how specific versions of a protein called Numb protect the key tumor suppressor p53 from destruction.

21 Dec 2017

Study findings could lead to less expensive and more effective cancer treatments

The latest generation of cancer treatments spring from the discovery that the human immune system is able to beat the disease. Like Dorothy in "The Wizard of Oz," what research teams around the world have spent decades searching for was right in their own backyard all along.

Silky webs of spiders may hold secrets to repairing our skeletons

Some secrets to repairing our skeletons might be found in the silky webs of spiders, according to recent experiments guided by supercomputers. Scientists involved say their results will help understand the details of osteoregeneration, or how bones repair themselves.

Stem cells remain healthy following low-dose X-ray exposure, say biophysicists

Biophysicists have shown that following low-dose exposure to X-rays (at 80 milligrays), stem cells remain healthy, proliferate, and do not accumulate DNA damage to be passed on to their progeny. The paper was published in the journal Aging.
