Organoids and Disease Models
Why are researchers growing mini-organs in orbit, and is there a business in it?
Chapter summary
because microgravity changes how three-dimensional cell clusters, organoids, grow and age, which can make them better models of human disease.
Key takeaways
- 1
Neural organoids flown on the ISS by Scripps Research and the New York Stem Cell Foundation showed lower proliferation and higher maturation markers than ground controls; glioblastoma organoids grown in orbit secreted proteins associated with aggressive disease, modelling advanced cancer better; a 2026 preprint found midbrain organoids survived a 40-day mission despite a hardware fault but lost dopaminergic neurons.
- 2
The business is research services for drug discovery and disease modelling, not products.
- 3
Setcoin scores organoid models 70, near-term, because the result is hard to reproduce on Earth and needs no product approval.
