Abnormal scarring is a serious threat resulting in non-healing chronic wounds or fibrosis. Scars form when fibroblasts, a type of cell of connective tissue, reach wounded skin and deposit plugs of extracellular matrix.

Medicinal plants: from genes to drugs

We eat plants, wear their products, burn them for fuel, and use them to build our houses. Plants are the very basis of the food chain on earth. They are also the source of oxygen in the atmosphere, and a treasure house containing a host of compounds that have biological effects on the body. Some of these chemicals are produced as self-defence, to guard against pests and diseases.
While most of us are stuffing ourselves with turkey and pumpkin pie at home on Thanksgiving Day, the staff at one Cedars-Sinai laboratory will be on the job, feeding stem cells.
When our skin is damaged, a whole set of biological processes springs into action to heal the wound. Now, researchers from the VIB-UGent Center for Inflammation Research have shown that one of the molecules involved in this, HMGB1, slows down wound healing.
Wound healing events in mucous tissues during early infection by Simian Immunodeficiency Virus, or SIV, guard some primate species against developing AIDS, a recent study has learned.
Like a swarm of construction workers in the aftermath of a destructive storm, cargo-filled, nanometer-sized spheres arrive on the scene following an acute kidney injury.
Researchers at Rensselaer Polytechnic Institute have developed a way to 3D print living skin, complete with blood vessels. The advancement, published online today in Tissue Engineering Part A, is a significant step toward creating grafts that are more like the skin our bodies produce naturally.
In what is believed to be the most comprehensive molecular characterization to date of the most common - and often treatment-resistant - form of kidney cancer, researchers at Johns Hopkins' departments of pathology and oncology, Johns Hopkins Kimmel Cancer Center, and the Johns Hopkins University School of Medicine report evidence for at least three distinct subtypes of clear cell renal cell carcinoma (ccRCC), along with new revelations about the proteins that define them.
