Fingernail-sized chip can repair damaged tissue in seconds
A new device can begin repairing damaged organs in seconds, heralding a major breakthrough for life-saving medicine. Developed at Ohio State University, the technology known as tissue nanotransfection (TNT) uses a small coin-sized silicon chip that "injects" genetic code into skin cells, converting them from one type to another.
Cell-infused 'spray-on-skin' helps leg ulcers heal more quickly
Spray-on medical solutions packed with cells certainly seem to be catching on. A new study published in The Lancet highlights a spray infused with skin cells and blood clotting proteins that helps leg ulcers heal quicker. Normally, the open wounds only undergo a compression bandage treatment and typically heal after six months. Patients who were also spritzed with the cell-imbued solution, however, experienced a rapid decrease in ulcer sizes soon after being treated. Three months into the regimen, 70 percent of those who had the mist applied were healed of the malady. Not only does the new remedy speed up the healing process, but it also avoids the need for a skin graft, another method used to hasten rehabilitation. Cost is a potential concern, but further tests are still needed to determine the therapy's practicality. [Image credit: Shutterstock]
