First demonstration of new hair follicle generation in an animal model
...or the first time that, like other animals such as newts
and salamanders, mammals have the power to regenerate. These findings are published in the May 17 issue of Nature. A better understanding of this process could lead to novel treatments for hair loss, other skin and hair disorders, and wounds. ...
Leeches ferry infection among newts

and other amphibians in North America. It does no... to reproduce. "This is the first evidence that newts
are getting infected through the bites of leeches," said Thomas R. Raffel, a postdoctoral researcher...
How fish mend a broken heart
...ve regeneration," they said. For instance, certain newts
or salamanders can regenerate limbs, spinal cord, retina, brain, and heart tissue. While progenitor cell populations have been identified within most mammalian organs, including skin, skeletal muscle, brain, and heart, these cells vary widely in fr...
Key to zebrafish heart regeneration uncovered
...of different types of organisms, such as axolotls, newts
and zebrafish, that have an elevated ability to regenerate lost or damaged tissue," said Kenneth Poss, Ph.D., senior researcher for the team, which published the findings on Nov. 3, 2006, in the journal Cell. First authors of the paper were Alexandra...
Newts which regrow their hearts
...s different. Unlike in the process with the heart, newts
develop a blastema in this case. Blastema cells have certain characteristics in common with stem cells, such as the development into different cell types. The cell biologists in Bad Nauheim injected isolated heart muscle cells into a newtâ€™s leg tha...
At the molecular level, the predator is the prey
... only organisms on Earth that can eat T. granulosa newts
and survive are some T. sirtalis garter snakes. TT...s a defense mechanism. In the case of T. granulosa newts
and T. sirtalis garter snakes, the interaction has gone far beyond that simple fangs-off arrangement...
Scientists discover that three overlapping signals in embryo help get the backbone right
...or the stem cell debate. That 1924 observation in newts
by Hans Spemann and Hilde Mangold earned Spemann the Nobel Prize in 1935 and generated the notion that embryonic cells don't know what they'll become until they get the proper signal. This concept is at the root of today's excitement over embryonic s...
Spleen may be source of versatile stem cells
...ck that can come fromstudies of lower animals like newts
and sponges. Combining theknowledge of Hox11's role in those animals with what we'd found aboutislet cell regeneration in mice helped us find this previously unknownexample of normal, controlled Hox11 expression in an adult mammal."Co-authors of the ...
