Specification 4.1.2.3 · Paper 1
Revise: Stem cellsBone marrow, the tissue inside bones, contains adult stem cells that can form several cell types, including different blood cells. For example, they produce red blood cells and white blood cells. Continual production is important because blood cells need replacing throughout life.
Paper 1, Paper 2
A stem cell found in particular tissues of the body that can differentiate into a limited range of related specialised cells.
Revise: Stem Cells and Their Use in MedicineAdult stem cells remain in particular tissues after early development. They produce new cells for growth and replace cells that are damaged or lost. Unlike embryonic stem cells, they can differentiate into only a limited range of related cell types.
Compare the range of cells produced: embryonic stem cells can form any type of body cell, whereas adult stem cells form a limited range of related cell types.
Immune rejection can affect donor adult stem cells as well as donor embryonic stem cells.
