Scientists Create Synthetic Prototissue Capable of Synchronized Beating

bristol news

Bristol, UK – The discovery, published in Nature Materials, is the first chemically programmed approach to producing an artificial tissue. The findings, which could have major health applications in the future, could see chemically programmed synthetic tissue being used to support failing living tissues and to cure specific diseases.

Human Retinas Grown in a Dish Explain How Color Vision Develops

john hopkins news

Baltimore, MD, USA – Biologists at Johns Hopkins University grew human retinas from scratch to determine how cells that allow people to see in color are made. The work, published in the journal Science, lays the foundation to develop therapies for eye diseases such as color blindness and macular degeneration. It also establishes lab-created "organoids" as a model to study human development on a cellular level.

Cancer Stem Cells Use “Normal” Genes in Abnormal Ways

colorado news

Denver, CO, USA – CDK1 is a “normal” protein – its presence drives cells through the cycle of replication. And MHC Class I molecules are “normal” as well – they present bits of proteins on the surfaces of cells for examination by the immune system. But a University of Colorado Cancer Center study published in the journal Cancer Research shows that a population of cancer cells marked by MHC Class I molecules and high CDK1 is anything but normal.

Cells in 'Little Brain' Have Distinctive Metabolic Needs

emory news

Atlanta, GA, USA – Cells' metabolic needs are not uniform across the brain, researchers have learned. "Knocking out" an enzyme that regulates mitochondria, cells' miniature power plants, specifically blocks the development of the mouse cerebellum more than the rest of the brain. The results are scheduled for publication in Science Advances.

UCLA Researchers Discover Aggressive Prostate and Lung Cancers Are Driven by Common Mechanisms

ucla news

Los Angeles, CA, USA – UCLA researchers have discovered a common process in the development of late-stage, small cell cancers of the prostate and lung. These shared molecular mechanisms could lead to the development of drugs to treat not just prostate and lung cancers, but small cell cancers of almost any organ.

CWRU Scientists Develop New Method to More Efficiently Generate Brain Stem Cells

case western

Cleveland, OH, USA – In two newly published papers, a scientific team at Case Western Reserve University School of Medicine reports on the discovery and implementation of a new, more efficient method for generating an important brain stem cell in the laboratory. The findings pave the way for greater understanding of the underlying mechanisms of neurological disorders of myelin and ultimately, possible new treatment and prevention options. The studies were published in the September issues of Nature Communications and Stem Cell Reports.
