Researchers discover mechanism that limits scar formation

Researchers from the University of Illinois at Chicago have discovered that an unexpected cellular response plays an important role in breaking down and inhibiting the formation of excess scar tissue in wound healing.

Matrix protein key to fighting viruses

Researchers from Durham University's Centre for Bioactive Chemistry are developing methods that show how proteins interact with cell membranes when a virus strikes. Using their approach, the team hopes to find new ways to ...

Fibroblasts invade at a snail's pace

A transcription factor known to drive the formation of fibroblasts during development also promotes their ability to invade and remodel surrounding tissues, report Rowe et al. in the February 9, 2009 issue of the Journal ...
