3D-printed skin with blood vessels
Researchers in Belgium recently proved that they have succeeded in creating a 3D-printed skin with blood vessels. This could be really promising for the future of organ transplantation, too. This skin-like material was created through the collaboration of a team of researchers from Rensselaer Polytechnic Institute and Yale Medical School. This material is made up mostly of human cells, but also some animal cells and other elements like collagen.
After weeks, the cells developed a vascular system and were injected into a mouse by injecting it with the organism. The skin began to attach to the animal’s circulatory system and became visible.
Pankaj Karande, prof at Rensselaer, said
This is extremely important because we know that there is actually a transfer of blood and nutrients into the graft that keeps it alive. Right now, whatever is available as a clinical product looks like a fictional Band-Aid. It offers some acceleration in wound healing, but ultimately it just falls flat and never really integrates into the host.
With CRISPR technology, editing the cells is now possible to make them less likely to be rejected. The next step will be to actually deliver the edited cells to their recipient. Completing this task will help save lives by providing better treatment for people with diabetes and pressure ulcers, who can delay the healing process. Additionally, you will be able to provide better care for people who need it.
Skin has been the latest advance that’s happened in medical field for a while now, as scientists have learnt how to 3D-print organs using an advanced blood vessel framework.
