Final answer:
The 4 main approaches to regenerative medicine using stem cells are described, and the option that does not describe one of these approaches is identified.
Step-by-step explanation:
The 4 main approaches to regenerative medicine using stem cells are:
- Stem cells from one individual are used to regenerate new tissues by surgically injecting them into a different individual (A)
- Stem cells are treated with drugs outside the body and then injected into the body to regenerate tissue (B)
- Biodegradable scaffolds are used to regenerate new tissues and organs outside the body and then are surgically inserted into the body (C)
- Drugs artificially stimulate stem cells within the body to regenerate tissues (D)
The option that does not describe one of the main approaches to regenerative medicine using stem cells is A) Stem Cells from one individual are used to regenerate new tissues by surgically injecting them into a different individual.
