In a major breakthrough, Scientists revealed the first ever 3D printed heart with tissues, cells, blood vessels, ventricles and chambers. This technology could help in heart transplant after it becomes fully functional. However, this is not the first time that 3D printing technology has been used in the medical word. Researchers have used the technology to create skin, spinal cells and corneas.
1. 3D corneas:
The first ever 3D corneas were printed by Newcastle University, the UK last year. Cornea the outer most lens of the eye controls and focuses the entry of light into the eye. There is a significant shortage of corneas worldwide, which means a lot of people die because of full or partial blindness because there is a scarcity of corneas and with the artificial corneas, the supply of corneas would be unlimited worldwide.
2. Spinal cells:
The University of California San Diego School of Medicine and the Institute of Engineering in Medicine came up with the idea of creating 3D cells for treating spinal injuries and they were successfully implanted into the cells of rats. The idea of creating spinal cells was to improve the growth of neuron across spinal cord injuries. It would help to repair the existing stems cells and control the muscles.
At the University of Toronto, in order to treat the wounds a gun like a device was made. This device has the potential to heal the deep wounds and aid the blood coating. The skin gun has materials that are present in the skin.
