This mobile bed Bioprinter can help wound healing

Wounds can affect the skin, but scientists are trying to speed up the process of treatment with a new device: a mobile bioprinter in bed that can help treat injured patients.

The Wake Forest Institute for Regenerative Medicine (WFIRM) has recently developed a mobile bioprinting system for the skin, which allows double-skinned skin to be printed directly into the wound. A team that published their findings in. T Scientific reports On February 12, it was discovered that such treatment, which would use the patient's own cells to "print" the skin and accelerate the treatment process, would be useful in the future for hospitals.

"Technology has the potential to eliminate the need for painful skin transplants that cause further distortion in patients suffering from major wounds or burns," said WFIRM Director Anthony Atala, "A mobile bioprinter, which can provide extensive wounds on the spot, could help speed up delivery of supplies and reduce costs for patients."

According to research, chronic, large or unhealthy wounds for patients can be expensive and take too much time to treat. However, bioprinter mobile beds can offer a faster, more cost-effective solution for burns and ulcers using a mixture of the main skin cells, including skin fibroblasts and epidermal keratinocytes, and "prints" the mixture onto the wounds to accelerate skin regeneration.

In order to use this bioprinter for the test, the team printed the skin on pre-clinical models. First, the main skin cells were mixed in a hydrogel and placed in a bioprinter. Then integrated imaging technology, which includes a wound scanning device, introduces information to the software to tell the print heads where to open cells in the wound in the wound. The group found that this system quickly imitates and accelerates the formation of skin cells, and hence wounds can be corrected in a shorter time.

After their attempt, the team's next move is testing a bioprinter in a clinical trial in humans. While skin transplantations are currently used to treat burns and wounds, due to the very limited availability of healthy skin for transmission, it may be difficult. With bioprinter, healthcare professionals can quickly recover the patient's skin cells without vaccination or donors.
