Cellular self-organization orchestrates ferroptosis propagation.

Cellular self-organization constrains ferroptosis propagation through spatial patterning and polarized lipid organization, limiting unbounded oxidative cell death waves.

• Why it matters: Understanding how tissue-scale organization influences cell death is crucial for insights into development and disease processes, yet this regulation remains poorly understood.
• What they did: The study combined in silico modeling and pharmacological experiments to analyze how cell density, alignment, and lipid polarization affect ferroptosis sensitivity and propagation, focusing on 2D cellular patterns.
• The result: Findings show that pattern-dependent susceptibility and lipid polarization work together to confine ferroptosis waves spatially, revealing self-organization as a systems-level mechanism for collective cell homeostasis.
