A med-tech startup has developed a fast and easy way to treat certain burn wounds with stem cells. RenovaCare harvests a variety of cells, including stem cells, from a healthy area of skin on a patient. Those cells are then suspended in a water-based solution, which is loaded into the company’s SkinGun and sprayed onto the wound. “The sprayer allows us to have a generous distribution of cells on the wound,” explained Roger Esteban-Vives, director of cell sciences at RenovaCare. The procedure takes about 90 minutes.
