3D Bioprinting: A New Frontier in Organ Transplantation

3D bioprinting, a prospective innovation in medical science, is making miracles in the field of organ transplantation and regenerative medicine. It follows the process of creating 3D tissue like structures by layering bioink, made of cells and other biomaterials. This neoteric technology has come a long way in the past few years and poses many opportunities.

In 2021 at the Tel Aviv University, Israel, researchers had achieved the impossible, something considered science fiction – they had bioprinted the first ever 3D vascularised engineered human heart. It was a functioning human heart that could contract, had cells, blood vessels, ventricles, and chambers present. A factor that makes this achievement distinct is that the patient’s cells itself were taken, reprogrammed and then used for printing the heart.

Potential Impact on Organ Transplantation

Going further, one of the largest challenges in the field of organ transplantation is the shortage of donors and the lengthy waiting list which leads to many deaths every year. Moreover, even if a donor is found there are other risks entailing organ transplantation such as the risk of rejection, wherein the body's immune system attacks the transplanted organ when a foreign body is recognised. Therefore, 3D bioprinting is considered a viable solution to these problems – when an organ is bioprinted with a patient's own cells, risk of rejection by the body is reduced, and the need for organ donors is also eliminated. This solution, if worked on, can possibly save many lives.

Challenges and Future Prospects

Nevertheless, 3-D bioprinting is still an experimental technology. It must overcome several obstacles before becoming a large-scale business. These obstacles include but are not limited to complexity of printed organs, their survival ability, long-term functioning in the body, and the technology required to expand this field to print larger and more complex organs. However, the initiative taken by multiple organizations such as the researchers at Tel Aviv University showcase the expansion in the field of 3D bioprinting and the high chance of attaining a real base of regenerative medicine.
