Scientists ‘herd’ cells in new approach to tissue engineering

Scientists ‘herd’ cells in new approach to tissue engineering

Sometimes it only takes a quick jolt of electricity to get a swarm of cells moving in the right direction. Researchers at UC Berkeley found that an electrical current can be used to orchestrate the flow of a group of cells, an achievement that could establish the basis for more controlled forms of tissue engineering and for potential applications such as “smart bandages” that use electrical stimulation to help heal wounds. In the experiments, described in a study published this week in the journal Nature Materials , the researchers used single layers of epithelial cells, the type of cells that bind together to form robust sheathes in skin, kidneys, cornea and other organs.

Free online software helps speed up genetic discoveries

Microarray analysis — a complex technology commonly used in many applications such as discovering genes, disease diagnosis, drug development and toxicological research — has just become easier and more user-friendly. A new advanced software program called Eureka-DMA provides a cost-free, graphical interface that allows bioinformaticians and bench-biologists alike to initiate analyses, and to investigate the data produced by microarrays.
