Come from Neibulasi California Lincoln university, the group that the researcher of polyclinic of equestrian Sa Zhu Sai and Masschusetts Institute of Technology forms developed printing ink of a kind of new-style biology to be used at 3D to print, include the plasma that contains a lot ofplaque among them. This can let the organization that biology 3D prints have heal property of improvement. The plaque in blood makes condense all round cut, and return blood-vessel of repair such as, the skin, muscle, the injury of the parenchyma such as tendon. Already proving to use the serous material that contains a lot ofplaque to regard an operation as cure in the past is useful, and its and live thing 3D prints technical photograph union can initiate brand-new medical treatment application.
The goal with ultimate “ is to print but embedded functional sex organizes a structure, in order to replace or the organization that repair is damaged. State machinery and Ali Tamayol of professor of material engineering assistant say the Bulasijia inside ” . One of “ challenges are to create a kind of structure, when the organization of embedded make choice of after injury or organ, can release unripe chief factor, start pair of heal and renewal process. The biology ink of ” this group contains the mixture of gel of alga acerbity salt and plaque cell. Be printed for biology and this is developed. However, the first phase is the ability that tests its to affect heal.
Compare with the similar ink photograph that does not have plaque, the initiative test that has to ink in the lab has delectable result. In the time that does not arrive one day, the ink that contains a lot ofplaque has made enough cell migratory the nick that makes an appointment with the man-made skin of 50% in order to cicatrization to go up, and the version that does not have plaque enclothed his only 5% . Ink still revealed the other and distinctive quality that plaque can offer, this is the ability that enhances ” cell what it can say for “ . It is inside 24 hours the dry cell with double above to without plaque form migratory. These dry cells can develop muscle, cartilage or skeleton.
Add chloridize calcium in ink subsequently, its form union between the polymer catenary of acerbity salt of a few alga. This makes material more ropy, but print to 3D still have enough plasticity. A lot of structures are printed with printing ink, include reseau, the structure that establish record and snakelike line. It is proved to be able to be printed effectively, show a heal body and the potential that can print.
In printing 3D calcic solution of structural immerge chloridize next with strengthening them further, this is the method that body itself uses. Scathing place connects regular meeting naturally elevatory calcic level, because this implements this kind of method,conduce to inside embedded body when the structure of alga acerbity salt that strengthens 3D biology to print. When development applies a standard to the operation, biology ink is OK also mix with the plaque of patient oneself and other cell. This kind of mixture is OK the risk that reacts the immunity that prints a structure to embedded 3D biology falls to lowest, because of the DNA that it will be based on him patient.
This discovery that studies a group is in a problem ” the 3D biology of support of project of organization of patient particularity Bioinks is printed ” introduce in detail in the paper, this paper is published on magazine of “Advanced Healthcare Materials” . Their project got academy of American national sanitation, neibulasi California tobacco is resident the support that fund studies in the Sa case of total hospital of dot and state of equestrian Sa Zhu Sai.
