Changes In Bioelectric Signals Cause Tadpoles To Grow Eyes In Back, Tail
2011-12-09 03:55:59

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...

Researchers have identified a new and relatively abundant pool of stem cells in the heart. The findings in the December issue of Cell Stem Cell, a Cell Press publication, show that these heart cells have the capacity for long-term expansion and can form a variety of cell types, including muscle, bone, neural and heart cells. The researchers say the discovery may lay a foundation for much needed regenerative therapies aimed to enhance tissue repair in the heart. The damaged heart...

In liver disease, extent of tissue damage depends on the balance between the generation of scar tissue and the regeneration of new liver cells. In a significant minority of people who get injury to their organs instead of repairing them, they form scars. This can progress to chronic liver disease and cirrhosis where the scarring is so extensive the liver is unable to clean blood or produce vital hormones and clotting factors. Liver scars also provide an ideal environment for the development...

Controlling a stem cell transplant recipient´s immune response may be major key to successful bone regeneration A new study in Nature Medicine describes how different types of immune system T-cells alternately discourage and encourage stem cells to regrow bone and tissue, bringing into sharp focus the importance of the transplant recipient's immune system in stem cell regeneration. The study, conducted at the Center for Craniofacial Molecular Biology at the Ostrow School of...
