Stem Cell Research: Promising Advances and Controversies

The video discusses the types of stem cells, highlighting the ethical dilemmas of embryonic stem cells and the non-controversial nature of adult stem cells. Doctor John Yoo's research at Cedars Sinai Medical Centre focuses on using adult stem cells to treat malignant brain tumors, leveraging their ability to target tumor cells. California's significant investment in stem cell research promises advancements despite ethical controversies.

What is one of the main ethical concerns associated with embryonic stem cells?

• They are difficult to obtain.

• They can only be used in specific medical conditions.

• Their use involves ethical dilemmas.

• They are less effective than adult stem cells.

What is the unique ability of the neural stem cells used by Dr. John Yoo?

• They can transform into any type of cell.

• They can target tumor cells wherever they are.

• They are derived from embryonic stem cells.

• They can only be used in brain surgeries.

From where does Dr. Yoo collect the adult stem cells for his research?

• Bone marrow

• Skin cells

• Embryos

• Blood

What is the current status of stem cell research in California?

• It is declining due to controversies.

• It is only focused on adult stem cells.

• It is in its early stages but well-funded.

• It is facing a lack of funding.

How much funding is available for stem cell research in California?

• $1 billion
