3D Printer Using Human Cells Print a Real Human Cornea:3D printer technologies have become difficult to believe. Scientists have developed a true cornea, not only developing a text that uses human cells by launching a new attempt for our eyes, the most sensitive organ of our bodies. Technology is said to be ready for use soon.
Our eyes will be entrusted to technology in the near future. The eyes that most people have problems because it is our most sensitive organ can be no problem due to similar developments that you will read soon. Scientists, who artificially produced the most advanced human corneas, used a 3D printer for this. The main material of the printer was human cells.
To do this, it was the most exhausting part of the job to find the right ink for a printer to use in the printout. Che Connon, a tissue engineer at Newcastle University, emphasized that the bio-ink must have very thin layers. At the same time, it had to be extremely hard to maintain its 3D structure. To obtain the right mix, the researchers used the corneas of the donors. Artificial proteins were added to the stem cells.
The cornea is the most important area where the lights entering our eyes pass before they hit the retina behind the eye. Injury, injury or infection of the cornea directly affects our vision quality, even causing blindness. Now damaged corneas are replaced by healthy corneas of people who donate their organs before they die. As a matter of fact, the number of healthy corneas decreases according to the World Health Organization. In addition, 5 million people worldwide are blinded by damage to their corneas.
The work of scientists also suggests artificial methods to counter these shortcomings. Whether or not healthy donor corneas are produced using healthy stem cells, they fill up a serious deficiency.
In order to analyze exactly what they would print, scientists who studied the corneas of volunteer people formed the 3D models of corneas. This template was then sent to a printer and the previously prepared bio-ink was used by the printer to print the template. So in a sense, this device produced an artificial organ with human cells. The result is a contact lense, but it's a complete cornea.
Scientists have said that there are some more work in front of them to actually place these corneas into the human eye. At the first stage, artificial corneas will be produced for the animals and the test results will be passed to the human subjects. Efforts are underway for the recent spread of technology.
