Immunoids: Building immunocompetent organoids from human pluripotent stem cells.

Immunoids integrating immune cells into human pluripotent stem cell-derived organoids reach advanced development stages, promising to revolutionize disease modeling and therapy.

• Why it matters: Understanding immune-tissue interactions is crucial for studying human development and disease, yet current models lack comprehensive immune integration, limiting translational potential.
• What they did: Researchers have developed immunoids by incorporating mature and immature immune populations into various organoids, enabling multilineage differentiation and immune co-development.
• The result: These immunoids enhance physiological relevance and are expected to significantly improve insights into disease mechanisms and personalized treatments, paving the way for precision medicine.
