The skins currently available are more like wound adhesives. Although these skins can help the wound heal better, their connection to the body is eventually lost and they never merge with the host cells. One of the barriers to using these shells is their inability to create new angles.
Researchers have been studying this for years. In their previous study, they showed that two types of human cells could be added to biological ink and then printed on similar skin structures. In their new project, the researchers showed that if the main elements, including endothelial cells, were combined with animal collagen and other structural cells, the cells would begin biological interaction with the vascular system within a few weeks. When researchers used the new skin for mouse models. Its blood vessels were able to communicate with the mice's body's arteries. This is a very important event in the field of skin tissue engineering because, as we know, blood and nutrient transfer to the transplanted organ can keep it alive.
