GCSE Combined Science · key term
A stem cell from an early embryo that can produce more stem cells and differentiate into most types of human cell.
Used by AQA and Edexcel
Specification 4.1.2.3 · Paper 1
Revise: Stem cellsHuman embryonic stem cells can also be cloned to produce many genetically identical stem cells, then stimulated to differentiate into most types of human cell. This is why they are of interest for growing replacement tissue.
Paper 1, Paper 2
A stem cell in an early embryo that can differentiate into any type of specialised body cell.
Revise: Stem Cells and Their Use in MedicineEmbryonic stem cells can differentiate into any type of specialised body cell, allowing these different tissues to develop.
Distinguish the developmental potential: embryonic stem cells can form most human cell types; adult bone marrow stem cells form a more limited range; meristem cells can form any plant cell type.
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.
