New 3D-bioprinter prints the skin from the patient's cells directly on the wound

Researchers are trying to create a 3D bioprinter to print new tissues from cells from specific patients in

over the past ten years.In 2014, a prototype device was unveiled that could print large sheets of human skin, which could then be cut to size and transplanted into a patient. Later, scientists presented a prototype of a portable printer capable of printing skin and applying it directly to a wound.

New development is a portablea device that can be freely moved within the hospital. The 3D bio-printer uses the patient's cells as a print material to avoid rejection of the transplanted skin. We are talking about fibroblasts, cells that help build a structure for healing wounds, and keratinocytes, which are the main cells of the skin.

In the near future, engineers will conduct clinicaltests of the device on real patients. In the future, a new 3D bio-printer may be used to treat burns, diabetic ulcers and other wounds that do not heal on their own.

Earlier it was reported that the European SpaceThe Agency (ESA) is developing a 3D bioprinter that will allow skin, bones, and whole body parts to be printed for astronauts who have been damaged on the ISS and in future space missions.
