Injury or disease in combination with too little vitamin D can be bad for the window to your eyes. The three-layer, transparent cornea at the front of the eyes focuses the light coming in. But its prominent position also puts it at risk for injury from an errant mascara wand or over-prodding finger or a car accident.
Scientists have found a new way to protect stem cells from harsh inflammation during wound repair. In a study recently published in the journal Cytotherapy, researchers in India discovered that treating mice with a common anti-inflammatory drug called celecoxib promoted stem cell survival and healing when they injected the cells into wounds.
Organs respond to injuries with the formation of new fibrous tissue, which can result in scarring. This process called fibrogenesis can now be monitored noninvasively on a molecular level, as American scientists report in the journal Angewandte Chemie.
Cells push out tiny feelers to probe their physical surroundings, but how much can these tiny sensors really discover? A new study led by Princeton University researchers and colleagues finds that the typical cell's environment is highly varied in the stiffness or flexibility of the surrounding tissue, and that to gain a meaningful amount of information about its surroundings, the cell must move around and change shape.
Electric fields can be used to guide neural stem cells transplanted into the brain towards a specific location. The research, published July 11 in the journal Stem Cell Reports, opens possibilities for effectively guiding stem cells to repair brain damage.
Sure, you know how old you are, but what about your cells? Are they the same age? Are they older, younger? Why does it matter?
The project is headed by Senior Research Associate of the Microorganism Genetics Lab Ayrat Kayumov and funded by Russian Science Foundation and Project 5-100. The results have been published in Scientific Reports.
A novel bandage alerts the nursing staff as soon as a wound starts healing badly. Sensors incorporated into the base material glow with a different intensity if the wound's pH level changes. This way even chronic wounds could be monitored at home.
