| Type | Potency Level | Can Become | Examples |
|---|---|---|---|
| Totipotent | Highest | Any cell type + extraembryonic tissues (placenta) | Fertilized egg, early embryonic cells (first 3-4 divisions) |
| Pluripotent | High | Any cell type in the body (all 3 germ layers) | Embryonic stem cells, induced pluripotent stem cells (iPSCs) |
| Multipotent | Limited | Several related cell types within one tissue | Bone marrow stem cells, neural stem cells, fat stem cells |
| Unipotent | Lowest | One specific cell type only | Skin stem cells (keratinocytes only) |
This diagram covers Types of Stem Cells by Potency within Stem Cells and Cell Differentiation for GCSE Biology. Stem cell types, differentiation processes, therapeutic applications, embryonic vs adult stem cells, and ethical considerations It is section 5 of 17 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.

Quick recall flashcards
What is a stem cell?
An undifferentiated cell that can divide to produce more stem cells (self-renewal) or differentiate into specialized cell types.
What does 'totipotent' mean?
The highest level of potency - cells can differentiate into any cell type in the organism plus extraembryonic tissues like the placenta. Example: fertilized egg.
