“The sugar trehalose protects cells” is a claim we have made for a number of years.  But, we needed more research to support this claim.  Here is a study that shows trehalose protects the endothelial cells and the corneal epithelial cells.  Trehalose functionality in this paper deals with treating dry eye which further supports our statements for improving hydration of the cells.  Endothelial cells are a specialized type of epithelial cell which forms the inner layer of blood vessels.  Epithelial cells help to protect or enclose organs; some produce mucus or other secretions.  Certain types of epithelial cells have tiny hairs called cilia, which help remove foreign substances.  The significance of these cells is that they play a key role in angiogenesis, the development of new blood vessels from pre-existing vessels.  Angiogenesis is a multi-step process that is important for both physiological and pathological development.  During angiogenesis, endothelial cells are activated and express matrix metalloproteinases (MMPs), which degrade the vascular basement membrane.  In response to environmental cues, endothelial cells secrete MMPs and then invade through the basement membrane to form new capillary networks.
