💡 Exam Tips
Key Distinctions
- Remember the hierarchy: Totipotent > Pluripotent > Multipotent > Unipotent
- Key difference: Embryonic = pluripotent, Adult = usually multipotent
- Don't confuse: Self-renewal (making more stem cells) vs differentiation (becoming specialised)
Exam Technique
- Plant vs Animal: Plant cells retain the ability to differentiate throughout life — animals mostly cannot
- Medical applications: Know at least 2 current treatments and 2 potential future ones
- Ethics: Be able to discuss both sides of the embryonic stem cell debate — always include a "however" counter-argument
Quick Check: Give ONE advantage of using adult stem cells rather than embryonic stem cells in medical treatment.
Any ONE of: No ethical concerns because no embryo is destroyed. If taken from the patient's own body, there is less risk of immune rejection. Lower risk of tumour formation compared to pluripotent embryonic stem cells.
