Virtual Cells Built from 4D AI Models and “Digital Twins” Could Speed Up Drug Discovery
AI-summarised brief · reviewed before publication
Researchers at the University of California, San Diego have created two complementary digital models of human cells that capture mitochondrial dynamics in four dimensions. Using high‑resolution 4D imaging, they built a deep‑learning system called MitoSpace and a physics‑based “digital twin” that reconstruct the constantly reshaping mitochondrial network. The AI can infer cellular health and energy output solely from mitochondrial morphology, outperforming conventional 2D imaging in revealing drug mechanisms. By simulating how mitochondria respond to pharmacological agents, the models enable rapid screening of compounds for diseases linked to mitochondrial dysfunction, including cancer, diabetes and Alzheimer’s. The approach promises to accelerate pre‑clinical testing and reduce reliance on costly, time‑intensive laboratory experiments.
