Suppressing implant fibrosis

Foreign body response can result in failure of biomaterials in vivo. Solvent-free crystals containing anti-fibrotic drugs now show the potential for long-term inhibition of fibrosis on a number of implantable devices in rodents and non-human primates.

    With their ability to give rise to many different cell types, stem cells have long been a target of scientists who seek to achieve control over their differentiation. New evidence suggests that stem cells influence their own fates through protein deposition and physical remodelling of their microenvironment.
