7. This These cells synthesize by genetic ingenious.
8. And this these cells are able to preserve the structure what that allows successful transplantation.
9. For creating a humans' organs is used hydrogel and biodegradable material.
10. The hydrogel is a combination of gelatin, fibrinogen, hyaluronic acid and glycerin with a high concentration of living cells.
11. First the printer creates a 3D object, then covers it with an outer shell of a degradable polymer.
12. After, the tissues are transplanted into the body, the polymeric shell gradually decomposes.
13. At the same time, cells begin to secrete a matrix that provides cell support.
