- What Makes Epithelial Cells Change Their Identity?
During development and during pathological processes in the adult, cells are constantly changing their function. One, well-characterized, cellular transition that occurs during development, as well as during wound healing, tissue fibrosis, and tumor metast ...

- Human Stem Cell Transplants Repair Rat Spinal Cords
Human nerve stem cells transplanted into rats' damaged spinal cords have survived, grown and in some cases connected with the rats' own spinal cord cells in a Johns Hopkins laboratory, overturning the long-held notion that spinal cords won' ...

- Instruction Manual For Creating A Molecular Nose
An artificial nose could be a real benefit at times: this kind of biosensor could sniff out poisons, explosives or drugs, for instance. Researchers at the Max Planck Institute for Polymer Research and the Max Planck Institute of Biochemistry recently reve ...

- OR Genes And Axonal Projections In Zebrafish
Thanks to Buck and Axel and colleagues, most neuroscientists are aware of the precise topographical map of the mouse olfactory nerve projection in which each olfactory sensory neuron (OSN) expresses a single odorant receptor (OR), and OSNs expressing a gi ...

- Proteasome Activator Enhances Survival Of Huntington's Disease Neuronal Model Cells
To function, each living cell needs both to build new and to degrade old or damaged proteins. To accomplish that, a number of intracellular systems work in concert to keep the cell healthy and from clogging up with damaged proteins. When proteins or pepti ...

- The Plasticity Of The Young Brain
Among the central mysteries of neurobiology is what properties of the young brain enable it to so adeptly wire itself to adapt to experience—a quality known as plasticity. The extraordinary plasticity of the young brain occurs only during a narrow window ...

- Fast And Slow-- How The Spinal Cord Controls The Speed Of Movement
Using a state-of-the-art technique to map neurons in the spinal cord of a larval zebrafish, Cornell University scientists have found a surprising pattern of activity that regulates the speed of the fish’s movement. The research may have long-term implicat ...

- Whole Body Regeneration From A Blood Vessel
For a lucky subset of vertebrates, losing an appendage is no big deal. As many an inquisitive child knows, salamanders can regenerate lost limbs or tails; and as lab investigators know, zebrafish can regrow lost fins. Of course, humans and other "hig ...

- Researchers Discover Gene Essential To Cerebellum Formation
Scientists have identified a molecular switch that causes the differentiation of neurons in the cerebellum, a part of the brain that helps to regulate motor functions. A study published this week in the scientific journal PNAS provides new information on ...
