Every organ in the body is capable, to some extent, of repairing itself after an injury. As part of this process, scar tissue forms and then recedes to make room for normal tissue when healing is complete.
And now, Manuka honey is proving a gamechanger in the fight against extremely drug-resistant infections, according to a new study published in the journal Frontiers.
According to the World Health Organization, cardiovascular disease has become the leading cause of death worldwide. However, vascular regeneration is a promising treatment for cardiovascular disease. Remodeling the endothelium - i.e., forming a confluent vascular endothelial cell monolayer on the lumen - plays a vital role in this process.
A new study published in the journal Nature shows that stem cells do work well to repair the damaged heart – but in an entirely different manner than was originally supposed. The study shows that stem cells, whether living or dead, when injected into the area of damage in the heart in mice, activate an intense acute inflammation. This triggers the classic wound healing response which finally results in the partial or complete recovery of mechanical function of the injured area.
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.
