11.4 Cell Differentiation

Front

What is cell differentiation?

Back

Process by which cells become specialized.

Front

What are stem cells?

Back

Undifferentiated cells that can develop into specialized cell types.

Front

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

Back

To serve as a repair system for the body.

Front

What is the difference between adult stem cells and embryonic stem cells?

Back

Adult stem cells are found in specific tissues and are limited in differentiation, while embryonic stem cells can differentiate into any cell type.

Front

What is a potential risk of stem cell therapy?

Back

Rejection by the immune system.

Front

What are the sources of stem cells?

Back

Embryos, umbilical cord blood, and adult tissues.

Front

What is the primary ethical issue with using embryonic stem cells?

Back

The moral status of the embryo.

Front

What is the role of stem cells in tissue regeneration?

Back

They can divide and differentiate to replace damaged or lost cells.

Front

What is the significance of pluripotent stem cells?

Back

They can give rise to nearly all cell types in the body.

Front

What are induced pluripotent stem cells (iPSCs)?

Back

Adult cells that have been genetically reprogrammed to an embryonic stem cell-like state.
