TED-Ed: What are stem cells? - Craig A. Kohn

The video discusses the concept of personalized medicine, emphasizing the uniqueness of individual medical needs. It introduces stem cells as a key area of research for creating personalized treatments. Stem cells are undifferentiated cells with the potential to become any cell type, offering possibilities for regenerative medicine. The video explains different types of stem cells, including adult, embryonic, and induced pluripotent stem cells, and their applications in treating diseases like leukemia. It highlights ongoing research aimed at using stem cells to understand body functions and develop specialized medicine.

What is the main reason why personalized medicine is important?

• All people listen to the same music.

• Everyone has the same medical needs.

• Medical treatments are universally effective.

• Individual health needs vary greatly.

What is the primary function of stem cells in the body?

• To replace worn-out cells.

• To protect the body like skin cells.

• To send signals like nerve cells.

• To contract like muscle cells.

How do stem cells contribute to treating leukemia?

• By enhancing immune response.

• By stopping cancer cell growth.

• By replacing damaged blood cells.

• By creating new bone marrow.

What distinguishes embryonic stem cells from adult stem cells?

• They are found in small numbers in tissues.

• They are pluripotent and can become any cell type.

• They are derived from bone marrow.

• They are used only in blood disease treatments.

What is the potential benefit of induced pluripotent stem cells?

• They are used exclusively for muscle repair.

• They can transform into any cell type.

• They are limited to liver cell functions.

• They can only become skin cells.
