Bones grown in lab could be used to repair badly damaged limbs

The video tutorial explains the process of growing bones from fat tissue stem cells, initially tested on rats, with human trials planned for later. It details the steps of scanning the injured bone to create a scaffold, extracting fat tissue via liposuction, and applying stem cells to grow a new bone over a month. The scan ensures the implant fits the broken bone perfectly.

What is the initial step in the process of growing bones from fat tissue stem cells?

• Directly implanting bones into the body

• Using stem cells from fat tissue

• Growing bones in a petri dish

• Injecting stem cells into the bloodstream

What is the purpose of scanning the injured bone?

• To determine the age of the bone

• To create a jellylike bone scaffold

• To measure the density of the bone

• To identify the type of bone

How is fat tissue extracted for the bone growth process?

• By using a needle biopsy

• Through a surgical incision

• Through a dietary supplement

• Via liposuction

What is the duration of the bone growth process using stem cells?

• One month

• Two weeks

• Two months

• One week

Why is it important for the implant to match the broken bone perfectly?

• To avoid the need for further surgery

• To ensure proper functionality and integration

• To prevent rejection by the body

• To ensure aesthetic appearance
