Episode notes
Organoids Unlock The Hidden Brain
- Brain organoids recreate early human brain development cell-by-cell, offering access we never had before.
- This access explains why neurological diseases remain largely incurable and opens paths to new treatments.
Self-Assembling Mini-Brains From Stem Cells
- Pluripotent stem cells can be guided to self-assemble into 3D neural tissues that fire and form microcircuits.
- After initial cues the cells follow genetic programs to build complex neural networks over months.
Vascularization Is The Scaling Bottleneck
- Current organoids reach ~0.5 cm and millions of cells but lack vascularization, limiting growth and longevity.
- Achieving vascularization is the key step to scale organoids toward adult-like complexity.
