Treatment of burn injuries may get easier as a group of Canadian scientists have developed a novel 3-D bioprinter that can treat severe skin burns avoiding conventional treatments like skin grafting or scaffolds. The newly developed handheld bioprinters deposit the skin precursor sheets directly onto the wound surface. The device is designed in a way that it can coat the bio-sheets over any non-flat, inclined skin surfaces in a uniform manner. The device has been tested on pig models and showed significant healing of injuries with a marked reduction in inflammation, scarring, and contraction.
Earlier the conventional treatment was skin grafts, scaffolds, and skin allograft substitutes that were not suitable for extensive burn injuries to the upper as well as lower layers of the skin. The novel 3-D Bioprinter is a new ray of hope for burn patients. Source: Economic Times
