Latest Regeneration Stories
Researchers at the University of California, San Francisco and the Stowers Institute for Medical Research have discovered that planarians, tiny flatworms fabled for their regenerative powers, completely lack centrosomes, cellular structures that organize the network of microtubules that pulls chromosomes apart during cell division.
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.
Damaged heart tissue is not known for having much inherent capacity for repair.
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.
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.
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.
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.
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.
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.
- In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
