Wounds can put the way to the skin, but scientists are trying to speed up the healing process with a new device: a mobile bed bioprinter that can help treat injured patients.
The Wake Forest Reconstructive Medicine Institute (WFIRM) recently developed a mobile skin bioprinting system that allows double skin to print directly on the wound. The team that published its conclusions in 2006 Scientific reports On February 12th, it was discovered that this type of treatment, which would use the patient's own cells to “print” the skin and accelerate the healing process, could be useful for hospitals in the future.

"Technology has the potential to eliminate the need for painful skin transplants leading to further dysfunction in patients suffering from major wounds or burns," said WFIRM director Anthony Atala, M.D. "A mobile bio printer that can provide extensive on-site wound management could help speed up care delivery and reduce patient costs."
According to studies, chronic, large or non-healing wounds can be expensive for patients and they have too much time to heal. However, a mobile bed bio printer can offer a faster, more cost-effective solution for burns and ulcers using the largest mixture of skin cells, including skin fibroblasts and epidermal keratinocytes, and "print" the mixture on wounds to speed up skin regeneration.
To put this bio-printer in the test, the team printed the skin on non-clinical models. First, the main skin cells were mixed in hydrogen and placed in a bio-printer. Further, the integrated imaging technology, which includes a scanning device for the wound, provides information to the software to inform the printheads where the cells are introduced into the layer by layer. The team found that this system quickly recurs and accelerates the formation of skin cells, so the wound can repair itself in a shorter period of time.
After the experiment, the next step for the team is to test the bio-printer in a human clinical trial. Although skin transplants are currently being used to treat burns and wounds, they can be difficult because of limited access to healthy skin. In the future, bioprinters can quickly restore patient's skin cells without grafting or donating.
