Anthony Atala gives an inspiring talk on the reproduction of cells and organs. This talk talks about our current state with cellular reproduction and where it will be headed with the help of 3D printers. This also shows us the need for this technology as currently organ donors do not match the number of recipients needing a transplant. Atala's talk about 3D printed organs was easily understandable for the average person, his images were captivating, and the success story of a person receiving a 3D printed bladder was inspiring. It clearly describes how they use biomaterials with cells and how they work, and shows the future of this technology and how it works. Anthony talks about how they use biomaterials and what they do to make cells inhabit them. These biomaterials must be able to work with your body and help regenerate cells. Anthony points out that they used biomaterials to replace and repair a patient's structure. The way they achieved this was that the biomaterials acted as a bridge over which cells could come together to reclaim the specific area. Adverse outcomes from these materials imply potential variability of the material from batch to batch, depending on the source, as well as the need to ensure the purity of the protein before administering it to the patient to avoid triggering an immune response. These scaffolds often have a limited range of properties and sometimes need to be optimized for stem cell culture. Although the use of biomaterials is an excellent substance for generating cells, there are disadvantages to the use of these materials and they require special care to be successfully implemented. When Anthony talked about biomaterials, he provided some details regarding how these structures work, but was missing a more visual demonstration or demonstration... halfway through the paper... personal. It helped him live a normal life. He started talking about the future of these machines and what they thought was possible and what is already becoming a reality. The ability to print solid organs is coming soon, and they're already looking for ways to improve it. This talk gave me a new look at technology and what is achievable. It was clearly spoken in an easy-to-understand language, and his use of real examples of a real kidney on stage was jaw-dropping. Furthermore, after listening to what he had to say, I predict that this technology will be greatly improved in the future, but how do we know if this technology is feasible? This speech managed to explain the topic clearly and provided good examples to give the reader a great understanding of the topic. Along with a success story, this added some evidence to support what Anthony is talking about.
