Stem cell treatments 'go deep' to regenerate sun-damaged skin
​Injected stem cells rebuild the skin's normal elastin network, study reports

Summary:Some plastic surgeons have been using stem cells to treat aging, sun-damaged skin. But while they've been getting good results, it's been unclear exactly how these treatments work to rejuvenate 'photoaged' facial skin. A new study finds that within a few weeks, stem cell treatment eliminates the sun-damaged elastin network and replacing them with normal, undamaged tissues and structures.

​Unique insight into development of the human brain: Model of the early embryonic brain
Date:May 25, 2020
Source:University of Copenhagen The Faculty of Health and Medical Sciences
Summary:Stem cell researchers have designed a model of an early embryonic brain. The model will increase our understanding of how the human brain develops and can thereby help to accelerate the development of stem cell treatments for brain disorders such as Parkinson's disease, epilepsy and dementia.

Image analysis technique provides better understanding of heart cell defects
A new algorithm combines gradient methods with fast Fourier transforms to quantify the organization of cardiac myofibrils
Date:May 19, 2020
Source: American Institute of PhysicsSummary:Many patients with heart disease face limited treatment options. Fortunately, stem cell biology has enabled researchers to produce large numbers of cardiomyocytes, which may be used in drug screens and cell-based therapies. However, current image analysis techniques don't allow researchers to analyze heterogeneous, multidirectional, striated myofibrils typical of immature cells. Researchers showcase an algorithm that combines gradient methods with fast Fourier transforms to quantify myofibril structures in heart cells.

Summary: Researchers have published the first comprehensive overview of the major changes that occur in mammalian skin cells as they prepare to heal wounds. Results from the study provide a blueprint for future investigation into pathological conditions associated with poor wound healing, such as in diabetic patients.

Little skates could hold the key to cartilage therapy in humans
Source:Marine Biological Laboratory
Summary:Unlike humans and other mammals, the skeletons of sharks, skates, and rays are made entirely of cartilage and they continue to grow that cartilage throughout adulthood. New research finds that adult skates go one step further than cartilage growth: They can also spontaneously repair injured cartilage. This is the first known example of adult cartilage repair in a research organism. The team also found that newly healed skate cartilage did not form scar tissue.
