3D bioprinting of organs has become a reality, and there are thousands of publications surrounding the field. The need for 3D bioprinting can be associated with many factors, including the increase in human lifespan, with a 6-years increase in lifespan between 2000 and 2019 alone. At the root of increasing lifespan is the biological limitation of the human body. An increase in the chronological age of humans is placing pressure on the biological age and health of individuals, driving the need for regenerative strategies in medicine that focus on rebuilding lost health.
