Key to zebrafish heart regeneration uncovered
...e closely resembles what happens when a salamander regenerates
a lost limb. In the salamander, the site of injury becomes the gathering point for a mass of undifferentiated stem, or progenitor, cells, which are immature cells with the potential to be transformed into other cell types. This mass of undifferentiat...
Newts which regrow their hearts
...f the cell cycle and indicates that the newt heart regenerates
without the involvement of stem cells. It also seems that the heart regeneration does not create typical wound healing tissue, called a blastema. Braun explains this finding: "The heart only has a relatively small number of different cell types. This...
Microreactor efficiently regenerates cofactors for biocatalysis
...nce, has developed a microreactor that efficiently regenerates
cofactors through enzyme-catalyzed reactions. "Enzymes are nature's catalysts, but in some cases, enzymes can not prompt a speedy chemical reaction," said Paul Kenis, a professor of chemical and biomolecular engineering at Illinois and a researcher ...
