3D Bioprinting: challenges and prospects of tissue printing
20 people die daily in anticipation of their turn for an organ transplant. Every year, the number of people on the waiting list for organ transplants becomes higher and higher, while the number of donors and transplants decreases.
Artificially grown human organs become a kind of "holy grail" to solve this problem. 20 years have passed since the first 3D printing of the human liver in 1999. Today, technology continues to evolve. In December 2018, in space under zero gravity conditions, human cartilage tissue from tissue spheroids (chondrospheres) was printed using magnetic levitation assembly using the Organ.Avt original magnetic bioprinter. The expected growth in 3D printing is estimated at 36% by 2022.
- What is the future direction for 3D bioprinting?
- Will 3D bioprinting technology be available only to those who can afford it?
- Are printed organs safe for humans? Who takes responsibility for safety?
- Printed organs to create an improved version of a person, won't this lead to inequality? For example, transplantation of muscles that do not tire and are capable of superpower, etc.
