Irvine, Calif., June 3, 2021 — A multidisciplinary research team led by Jonathan Lakey, Ph.D., professor of surgery and biomedical engineering at the University of California, Irvine, has developed a biomaterial for pancreatic islet transplants that doesn’t trigger the body’s immune response. Based on stem cell technology, hybrid alginate offers a possible long-term treatment for Type 1 diabetes, an autoimmune reaction that destroys pancreatic islets’ beta cells, which regulate blood glucose levels.

Scientists at Sanford Burnham Prebys Medical Discovery Institute have created a drug that can lure stem cells to damaged tissue and improve treatment efficacy—a scientific first and major advance for the field of regenerative medicine. The discovery, published in the Proceedings of the National Academy of Sciences (PNAS), could improve current stem cell therapies designed to treat such neurological disorders as spinal cord injury, stroke, amyotrophic lateral sclerosis (ALS) and other neurodegenerative disorders; and expand their use to new conditions, such as heart disease or arthritis.

UCLA researchers have identified a compound that can reproduce the effect of exercise in muscle cells in mice. The findings are published today in the journal Cell Reports Medicine.
Imagine this: A patient learns that they are losing their sight because an eye disease has damaged crucial cells in their retina. Then, under the care of their doctor, they simply grow some new retinal cells, restoring their vision.
Although science hasn’t yet delivered this happy ending, researchers are working on it – with help from the humble zebrafish. When a zebrafish loses its retinal cells, it grows new ones. This observation has encouraged scientists to try hacking the zebrafish’s innate regenerative capacity to learn how to treat human disease. That is why among the National Eye Institute’s 1,200 active research projects, nearly 80 incorporate zebrafish.

A new study suggests that communication between skeletal muscle cells and muscle fibers promotes muscle growth. Adult muscle stem cells, called satellite cells, release extracellular vesicles that are delivered to muscle fibers responsible for contraction, to promote this muscle growth. The first-of-its-kind study is published ahead of print in the journal Function.

The authors found that ecdysone, a steroid hormone produced by fruit flies, stimulates intestinal stem cell growth and causes the gut of the female fruit fly to grow in size, as well as other critical changes.

A new study shows how stem cells – which can contribute to creating many parts of the body, not just one organ or body part – are able to postpone their own death in order to respond to an injury that needs their attention. The study was done in planarians, which are tiny worms used as model organisms to study regeneration because of their ability to recover from any injury using stem cells.
