How Surgeons Remain Focused: Organ-transplant surgeons have an impressive set of skills. Steady hands, thick skin, and an ability to concentrate for hours. While the duration of surgery differs, surgeons must be on call around the clock and ready to perform surgery at any hour.

What is 3D Bioprinting?
3D bioprinting is the process of generating spatially-controlled cell patterns using 3D printing technology, where cell function and viability are preserved within the printed construct. The first patent related to this technology was filed in the United States in 2003 and granted in 2006. 3D bioprinting is being applied to regenerative medicine to address the need for tissues and organs suitable for transplantation. Compared with non-biological printing, 3D bioprinting involves additional complexities, such as the choice of materials, cell types, growth and differentiation factors, and technical challenges related to the sensitivities of living cells and the construction of tissues. Addressing these complexities requires the integration of technologies from the fields of engineering, biomaterials science, cell biology, physics, and medicine. 3D bioprinting has already been used for the generation and transplantation of several tissues, including multilayered skin, bone, vascular grafts, tracheal splints, heart tissue and cartilaginous structures. Other applications include developing high-throughput 3D-bioprinted tissue models for research, drug discovery and toxicology.
