3D Bioprinting is a rapidly evolving technology that holds great potential for advancing the medical field, whether through the creation of living tissues and organs or personalized treatments tailored to the specific needs of each patient. While traditional 3D printing models rely on the use of plastic or metals, 3D bioprinting utilizes 3D printed bioinks, which are living cells combined with natural synthetic biomaterials, to construct natural tissue-like 3D structures.
In early experiments, the focus was on printing simpler forms of tissues such as skin and cartilage, as they did not require the use of complex blood vessel networks. These networks became easier to produce as these technologies became more advanced and easier and efficient to use, opening new possibilities for personalized treatment, drug testing, and organ transplants.
Tel Aviv University’s Successful Experiment
Such advancements can especially be seen in 2019, where Tel Aviv University scientists successfully 3D bioprinted a human heart using the patient’s cells. This was one of the first cases where bioprinting had been able to efficiently replicate and produce fully functioning blood vessels, chambers, and components that matched those of the patient’s body.
This case was significant as it showcased the capabilities of 3D bioprinting as a source to prevent the risk of organ rejection, which is a common result of many organ transplant procedures, rising as a potential source of treatment tailored to the needs and biological profile of the respective patients. As healthcare continues to advance, 3D bioprinting continues to rise as a source of treatment, overcoming medical obstacles and bridging healthcare disparities.
