Scottish scientists make 3D stem cell printer

The video discusses the use of a 3D stem cell printer that utilizes two types of bio ink: one containing stem cells and another without. The printer can adjust the size and number of stem cells in droplets, printing them in alternating layers. This technology holds the potential to create new organs for transplant in the future.

From where are the stem cells used in the 3D printing process derived?

• A mature adult cell

• An embryo developed for several days

• A synthetic laboratory culture

• A fully developed organ

What are the two types of bio ink used in the 3D stem cell printer?

• One with nutrients and one with water

• One with chemicals and one with proteins

• One with DNA and one with RNA

• One with stem cells and one without

How does the 3D printer arrange the bio ink during the printing process?

• In alternating layers

• In a single continuous layer

• In a spiral pattern

• In a random distribution

What is a potential future use of the 3D stem cell printing technology?

• Manufacturing electronic devices

• Producing synthetic food

• Developing new organs for transplant

• Creating artificial limbs

What can the printer adjust in the droplets during the printing process?

• The color of the ink

• The temperature of the medium

• The speed of printing

• The size and number of stem cells
