Episode notes
Organoids Mimic Human Tissue
- Organoids are 3D tissue clumps derived from pluripotent stem cells resembling small organs. - They allow studying tissue development and drug responses outside the human body.
Blood Vessels Grow With Organoids
- Researchers accidentally found blood vessel cells forming alongside organoids during stem cell transformation. - They then developed a molecular cocktail to grow organs and vessels simultaneously to better mimic real organs.
Lab-Grown Organs Are Distant Goal
- Full-size organs remain distant due to need for large blood vessels and organ complexity. - Current organoids are a foundational step toward lab-grown organs but require more research.
