Building artificial intelligence virtual tissue (AIVT) for tissue state representation, feature prediction, and dynamic simulation
🤖 AI Summary
Traditional computational models struggle to capture the complex dynamics of tissues as multiscale, spatially structured biological systems in both health and disease. To address this limitation, this work introduces the Artificial Intelligence Virtual Tissue (AIVT) framework—the first of its kind—to integrate spatially resolved multimodal biological data, deep learning, and generative AI into a unified, dynamically controllable digital twin of tissue. This framework enables precise characterization of tissue states, prediction of cross-scale molecular and morphological features, and simulation of their spatiotemporal evolution. By overcoming the constraints of conventional modeling approaches in spatial resolution and dynamism, AIVT establishes a novel paradigm for elucidating disease mechanisms and designing therapeutic interventions.
📝 Abstract
Modeling tissue states and their transitions is essential for understanding tissue homeostasis in health and pathological remodeling in disease. However, conventional computational modeling approaches are inadequate to capture the complexity of tissues as spatially organized, multiscale biological systems. Artificial intelligence (AI) has shown a remarkable ability for representing intricate systems, creating new opportunities to characterize tissue states and their transitions. Here, we propose the concept of AI virtual tissue (AIVT), an AI framework grounded in spatial multimodal data for modeling tissues in health and disease. AIVT is designed to learn unified, spatially resolved, and dynamically manipulatable representations of tissue state, enabling tissue state representation and analysis, molecular and morphological feature prediction, and simulation of spatiotemporal tissue dynamics. We outline the fundamental assumptions, core capabilities, architectural components, as well as data and algorithm foundations of AIVT as a framework for AI-driven tissue modeling.
