🧬 Types of Stem Cells by Source

1. Embryonic Stem Cells (ESCs)

  • Source: Inner cell mass of blastocyst (5-6 day old embryo)
  • Potency: Pluripotent - can become any cell type in the body
  • Advantages: Unlimited growth potential, can differentiate into any cell type
  • Disadvantages: Ethical concerns, potential for tumor formation
  • Applications: Research, potential treatments for spinal cord injuries, diabetes

2. Adult Stem Cells

  • Source: Various adult tissues (bone marrow, fat, brain, skin)
  • Potency: Usually multipotent - limited to cells of their tissue of origin
  • Advantages: No ethical concerns, lower tumor risk, can use patient's own cells
  • Disadvantages: Limited potency, harder to isolate and grow
  • Applications: Bone marrow transplants, skin grafts, blood disorders

3. Induced Pluripotent Stem Cells (iPSCs)

  • Source: Adult cells reprogrammed back to embryonic-like state
  • Method: Scientists introduce specific proteins that "reprogram" adult cells back to a stem cell state
  • Advantages: Pluripotent like ESCs but without ethical concerns
  • Applications: Disease modeling, drug testing, personalized medicine

Practice Questions for Stem Cells and Cell Differentiation

What is a stem cell?

  • A. An undifferentiated cell that can divide to produce many cell types
  • B. A specialized cell found only in plant roots

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.
