3D printing is a really promising technology – not only for applications in material engineering, but also in modern medicine. Today, experts from the Wake Forest Research Institute of Regenerative Medicine in the United States presented the results of testing their new unique 3D printer, which has the ability to print full layers of skin for healing and tightening large and complex wounds, and the technology of the new printer is based on the existing living cell technology. from the cellular tissues of the patient, thereby significantly reducing the degree of rejection of new skin.
By itself, the printer is a fairly compact installation that is easy to transport and install in an average hospital – and it is based on the traditional technology of 3D-ink, with non-standard stem cell selection techniques from which you can create almost any type of cell, including and skin cells. Thus, the new bioprinter uses this technique to separate the two main components in the formation of new skin layers – the fioblasts, which create the skin structure itself, and the curtinocytes, which, in turn, form the skin.
And this is done fairly quickly and efficiently – a separate module is attached to the patient, connected to the 3D printer, and the printer itself applies new skin layers to the damaged areas of the patient's body, in parallel with this, adapting and cutting them where necessary. This allows not only to form a sufficiently correct and high-quality skin, but also to stop possible rejection, which is a very common and annoying problem in modern regenerative medicine.
It is worth noting the fact that a bioprinter of this type uses for printing and drawing up the skin layers of the patient’s own cell, thereby ensuring really fast healing of even the widest and most problematic wounds. Of course, in order for the process to go as it should, the patient first goes through a biopsy stage and then is prepared for an immediate procedure.
