Stem Cells

Researchers have developed a biodegradable patch engineered from human cells that could be used to correct infant congenital heart defects, limiting the need for multiple invasive surgeries and outlasting current non-living, non-degradable patches.

Multiple sclerosis (MS) is a debilitating disease with few treatment options. But in a new clinical trial, scientists have tested a promising new therapy involving injections of stem cells, which seems to slow progression of the disease.

Vitamin B12 doesn't get much time in the spotlight, but as well as its role in red blood cell formation and DNA synthesis, scientists have now found that it is key to cellular reprogramming and tissue regeneration, as well as curtailing inflammation.

A huge multidisciplinary team at NYU Langone Health has successfully undertaken the world’s first whole-eye and partial-face transplant. The landmark surgery opens new possibilities for future advancements in vision therapies.

Cells from two genetically distinct macaque embryos have been combined, resulting in the first chimeric primate live birth. The newborn male's green glow reveals how large a part the injected stem cells played in development, stunning scientists.

Researchers have found that osteoarthritis is caused by the depletion of specialized gene-expressing cartilage-forming stem cells and found a way to treat and reverse the condition, instead of just managing its symptoms.

In what will soon be commonplace in drug research, scientists have used an artificial-intelligence algorithmic program to identify a compound, currently used in antimalarial treatment, that can effectively reverse the bone deterioration of osteoporosis.

Researchers have used human neural stem cells to 3D print functional brain tissue that mimics the architecture of the cerebral cortex, the brain’s outermost layer, and has the potential to provide individualized repairs to brain injuries.

Scientists at Stanford Medicine have tested a new potential treatment for Alzheimer’s disease in mice. The therapy involves transplanting blood stem cells from healthy mice into those with the disease, which helps replace defective neural cells.

Researchers created an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of embryonic development that may provide answers about birth defects and infertility.

In a world first, Budapest Zoo gorilla Liesel has received stem-cell therapy for her arthritis. It's hoped that this groundbreaking procedure, which aims to rejuvenate her damaged joint cartilage, will not just help her but be adapted for human use too.

In a phase 1 clinical trial, scientists have demonstrated that corneal transplants, grown from a patient’s own stem cells, can successfully restore some vision after an eye injury.
