Bioprinter prints skin directly onto a wound

Developed by Canadian scientists, a 3D printer treats severe burns by printing new skin cells directly on the wound. The device will accelerate the treatment of "severe" patients with significant skin lesions.

Scientists from Canada have successfully tested a new bioprinter for the treatment of wounds and burn skin lesions. Experiments on pigs showed that the device allows you to quickly and safely deliver biomaterial directly to the wound.

According to hightech.plus, all modern burn treatment methods have certain disadvantages. For example, the effect of using collagen scaffolds largely depends on the cells surrounding the wound. Another treatment method, which involves preparing “skin substitutes” in the laboratory, takes a very long time before transplanting the patient.

The basis of the biomaterial - the future "ink" for transplantation - fibrin protein and mesenchymal table cells. During treatment, fibrin sheets "print" directly onto the wound, which contributes to the growth of new cells at the site of the lesion.

The wounds treated in this way healed well, less often became inflamed and scarred compared with the treatment based on the collagen scaffold, experiments on large laboratory animals showed.

“The potential of the bioprinter goes far beyond the treatment of burn injuries and can be used for other purposes where safe cell delivery is needed,” the scientists are sure. Their assumptions will be verified in the next stages of research. The device is still in the prototype stage.

Another bioprinter for the treatment of skin lesions was developed by scientists from the United States. The principle of technology coincides with the Canadian method, however, scientists use other types of cells for treatment.
