⚖️ Ethical Considerations

Embryonic Stem Cell Research:

Concerns:
- Involves destruction of human embryos
- Questions about when life begins
- Consent and commercialization issues
Regulations:
- Vary by country - some ban it entirely, others allow with restrictions
- Usually limited to excess IVF embryos
- Strict oversight and ethical review required

Alternatives to Address Ethical Concerns:

Adult stem cells: No ethical issues as no embryos involved
iPSCs: Pluripotent without using embryos
Umbilical cord blood: Rich source of stem cells, collected harmlessly

Quick Recall Flashcards

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.
