Massachusetts Institute of Technology (MIT) and Boston Children’s Hospital researchers have discovered a way to prevent fibrosis from forming around medical device implants by blocking certain cells.
The body’s immune system usually attacks implanted medical devices that are used for drug delivery, sensing or tissue regeneration. Defense cells in the body try to isolate the foreign material from devices and create dense scar tissue around them. The scar tissue prevents the devices from doing what they’re supposed to.
Researchers found that blocking the molecule that is part of the fibrosis process prevents scar tissue from forming, according to an MIT news release.
