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.

Researchers identify physiological mechanism that maintains regenerative capacity of muscle stem cells

Researchers at UPF, the National Centre for Cardiovascular Research, ICREA and Ciberned have identified a physiological mechanism that maintains the regenerative capacity of muscle stem cells, and surprisingly resists the passage of time far more than expected, until geriatric age.

New research on small non-coding RNAs and SARS-CoV-2

A recently published mini-review in the Frontiers in Microbiology on the altered expression of small non-coding RNAs during coronavirus-mediated infections.

Happiness neurotransmitter serotonin plays role in evolutionary expansion of the neocortex

During human evolution, the size of the brain increased, especially in a particular part called the neocortex.

Researchers find a new therapeutic approach to combat leukemia

Leukemia frequently originates from the so-called leukemic stem cell, which resides in a tumor promoting and protecting niche within the bone marrow. Scientists from the Max Planck Institute of Biochemistry in Martinsried, Germany, have found a new way to make these cells vulnerable by specifically dislodging these cells from their niches.

Researchers develop lab-grown lung model to study SARS-CoV-2 infection

A team of Duke University researchers has developed a lab-grown living lung model that mimics the tiny air sacs of the lungs where coronavirus infection and serious lung damage take place.

New method for producing FTVI enzyme can help improve cord blood transplants

A new way of producing an enzyme called fucosyltransferase VI (FTVI) in the lab could help enhance the therapeutic potential of cord blood transplants.

Study reveals why oxygen deficiency impairs brain cells

Brain cell dysfunction in low oxygen is, surprisingly, caused by the very same responder system that is intended to be protective, according to a new published study by a team of researchers at the Case Western Reserve University School of Medicine.

Brain metabolic changes associated with loss of smell in COVID-19

A recent study detailed in a preprint paper published in medRxiv, researchers from Belgium, discuss how they investigated possible central nervous system (CNS) involvement in COVID-19 patients with a sudden loss of smell using a hybrid positron emission tomography (PET)-magnetic resonance imaging (MRI) system (PET-MR).

Study unravels consequences of mating at the molecular level

While it is known that stem cells have the ability to develop into all tissues in a precisely regulated process, the way environmental cues affect stem cell behavior has remained poorly understood.

Protein delivery to the testes restores male fertility in mice

According to the Mayo Clinic, about 15% of couples are infertile, and male infertility plays a role in over one-third of these cases.

Bioceramic implant can stimulate skull bone regeneration

A bioceramic implant has proved to stimulate regeneration of natural skull bone, so that even large cranial defects can be repaired in a way that has not been possible before. The research, led from the University of Gothenburg, is now presented in the scientific journal PNAS.

Researchers report the discovery of innate immune signaling pathway in fibroblasts

Vanderbilt University researchers have reported the counterintuitive discovery that certain chemotherapeutic agents used to treat tumors can have the opposite effect of tissue overgrowth in normal, intact mammary glands, epidermis and hair follicles.

Monkey study shows a causal link between white patch and vocal behavior

It's not a coincidence that dogs are cuter than wolves, or that goats at a petting zoo have shorter horns and friendlier demeanors than their wild ancestors.

Synthetic signals could help control tissue regeneration, guide cellular therapies

For a tiny embryo to develop into an adult organism, its cells must develop in precise patterns and interact with their neighbors in carefully orchestrated ways.

Tech Spotlight honors ISSCR's stem cell based clinical trials guide

The ISSCR's Stem Cell-Based Clinical Trials: Practical Advice for Physicians and Ethics/Institutional Review Committees was honored today by Tech Spotlight at Harvard Kennedy School's Belfer Center.

Two studies show the benefit of collaborative research on childhood blood disorders

When a child has a rare blood disorder, clinicians can struggle to find the best diagnostic and treatment methods.

Researchers reveal potential mechanisms behind the healing power of extracellular vesicles

Extracellular vesicles (EVs) -- nanometer sized messengers that travel between cells to deliver cues and cargo -- are promising tools for the next generation of therapies for everything from autoimmune and neurodegenerative diseases to cancer and tissue injury.

Study uncovers the mechanism behind bone marrow failure in Fanconi anemia

Fanconi anaemia (FA) is a genetic disease affecting small children characterized by bone-marrow failure, developmental abnormalities and predisposition to multiple forms of cancer.

Scientists engineer tissue grafts for personalized joint replacement

The temporomandibular joint (TMJ), which forms the back portion of the lower jaw and connects your jaw to your skull, is an anatomically complex and highly loaded structure consisting of cartilage and bone.
