(Ivanhoe Newswire) — Damaged heart tissue typically doesn´t repair itself, but scientists may have identified signals that are able to coax the heart into producing replacement cardiac muscle cells. Using a zebrafish model system, researchers have identified a family of molecules that can stimulate stem cells to develop into beating heart muscle cells. "Despite advances in modern medicine, management of myocardial infarction and heart failure remains a major challenge," senior...

Damaged heart tissue is not known for having much inherent capacity for repair. But now, scientists are closing in on signals that may be able to coax the heart into producing replacement cardiac muscle cells. Using a zebrafish model system, researchers have identified a family of molecules that can stimulate stem cells to develop into beating heart muscle cells. The research, published by Cell Press in the December 21st issue of the journal Chemistry & Biology, may pave the way towards...

UK scientists create a functional model of the extracellular matrix which could lead to advances in regenerative medicine Scientists at the National Physical Laboratory (NPL) have created a functional model of the native extracellular matrix that provides structural support to cells to aid growth and proliferation. The model could lead to advances in regenerative medicine. The extracellular matrix (ECM) provides the physical and chemical conditions that enable the development of all...

Researchers Study Hellbender Salamanders For Answers For Global Amphibian Decline
2011-12-20 10:43:34

A new study co-authored by University of Florida researchers on the endangered Ozark Hellbender giant salamander is the first to detail its skin microbes, the bacteria and fungi that defend against pathogens. Published today in the online journal PLoS One, the study details changes in the salamander's declining health and habitat, and could provide a baseline for how changing ecosystems are affecting the rapid decline of amphibians worldwide. "Scientists and biologists view amphibians...

Hydrogel Helps Grow New, Scar-free Skin For 3rd Degree Burn Patients
2011-12-14 05:33:03

Johns Hopkins researchers have developed a jelly-like material and wound treatment method that, in early experiments on skin damaged by severe burns, appeared to regenerate healthy, scar-free tissue. In the Dec. 12-16 online Early Edition of Proceedings of the National Academy of Sciences, the researchers reported their promising results from mouse tissue tests. The new treatment has not yet been tested on human patients. But the researchers say the procedure, which promotes the formation...

Changes In Bioelectric Signals Cause Tadpoles To Grow Eyes In Back, Tail

For the first time, scientists have altered natural bioelectrical communication among cells to directly specify the type of new organ to be created at a particular location within a vertebrate organism. Using genetic manipulation of membrane voltage in Xenopus (frog) embryos, biologists at Tufts University's School of Arts and Sciences were able to cause tadpoles to grow eyes outside of the head area. The researchers achieved most surprising results when they manipulated membrane voltage...

Neuroscientists find genetic trigger that makes stem cells differentiate in nose epithelia University of California, Berkeley, neuroscientists have discovered a genetic trigger that makes the nose renew its smell sensors, providing hope for new therapies for people who have lost their sense of smell due to trauma or old age. The gene tells olfactory stem cells the adult tissue stem cells in the nose to mature into the sensory neurons that detect odors and relay that information to the...

(Ivanhoe Newswire) -- A newly discovered and flourishing pool of stem cells in the heart has the ability for long-term expansion, and can form a variety of cell types, including muscle, bone, neural and heart cells. A damaged heart often doesn´t repair itself well, so the discovery of these stem cells may lay a foundation for much needed regenerative therapies aimed to enhance tissue repair in the heart. "In the end, we want to know how to preserve the stem cells that are there and...

Damage to podocytes -- a specialized type of epithelial cell in the kidney -- occurs in more than 90 percent of all chronic kidney disease. Now researchers at the Stanford University School of Medicine have uncovered an unexpected pathway that reveals for the first time how these cells may regenerate and renew themselves during normal kidney function. This finding is an important step toward one day therapeutically coaxing the cells to divide, which could be used to treat people with...


Word of the Day
