Researchers at Georgia Reagents University, Medical College of Georgia have discovered a signaling molecule that helps stem cells to survive in a low-oxygen environment, such as inside the bone marrow. This discovery is a significant advance in understanding the way stem cells works in their natural environment thus aiding researchers in the development of more effective therapies to combat bone loss as the world population ages.
Scientists in the US (UC, UCSD) and China (Wuhan) have found a way to convert stem cells into functional neurons. The researchers were able to suppress an RNA-binding protein, inducing the stem cells to become neurons. This gives hope for a treatment for neurodegenerative diseases such as Huntington’s, Parkinson’s, Alzheimer’s, Multiple Sclerosis, and Amyotrophic Lateral Sclerosis (ALS or Lou Gehrig’s disease), which will afflict one in four Americans over their lifetime.
Researchers at the University of California, San Diego and the University of Sheffield have worked together to find a way to improve stem cell scaffolding through sticky spots scattered throughout the extra-cellular matrix. The improvement in scaffolding will lead to better stem cell treatments in many areas. Right now, scaffolds are being used in tandem with stem cells to grow new tracheas, teeth, cartilage, organs and much more.
