Printing skin directly on wounds - interesting science news

Researchers have developed a mobile bio-printer, which can allow bi-layered skin to be printed directly into the wound. The system can scan the wound to measure its dimensions accurately and then directly deposit the skin onto the wound, providing direct on-site management.

While the current gold-standard is to use skin grafts its major limitation is the limited region from which it can be harvested and the skin could be rejected too.

For this new system the fibroblasts and keratinocytes, which can be easily isolated from the skin and expanded, are mixed in a hydrogel and placed in the bioprinter. These cells are then deposited in directly in the wound so that new skin can grow outwards from the centre of the wound.
