To grow or not to grow: a step forward in adult vertebrate tissue regeneration

The reason why some animals can regenerate tissues after severe organ loss or amputation while others, such as humans, cannot renew some structures has always intrigued scientists. In a new study, researchers show, for the first time, that zebrafish regenerates its caudal fin by a process that involves a specific channel in the cell membrane, called V-ATPase, that pumps hydrogen ions, generating an electrical current.

New technique for identifying gene-enhancers

Berkeley Lab researchers led the development of a new technique for identifying gene enhancers - sequences of DNA that act to amplify the expression of a specific gene - in the genomes of humans and other mammals. Called SIF-seq, this new technique complements existing genomic tools, such as ChIP-seq, and offers additional benefits.

Microfluidic device with artificial arteries measures drugs' influence on blood clotting

A new microfluidic method for evaluating drugs commonly used for preventing heart attacks has found that while aspirin can prevent dangerous blood clots in some at-risk patients, it may not be effective in all patients with narrowed arteries. The study, which involved 14 human subjects, used a device that simulated blood flowing through narrowed coronary arteries to assess effects of anti-clotting drugs.

A new way to make muscle cells from human stem cells

As stem cells continue their gradual transition from the lab to the clinic, a research group at the University of Wisconsin-Madison has discovered a new way to make large concentrations of skeletal muscle cells and muscle progenitors from human stem cells.
