Moreover, unlike text data, single-cell data is unordered and exhibits a unique tabular structure that current single-cell FMs overlook. We introduce Tabula, a privacy-preserving FM designed with federated learning (FL) that explicitly models the tabular structure of single-cell data. To deploy Tabula, we further developed Chiron, a decentralized AI agent-enabled platform for collaborative training across institutions without sharing raw data. Beyond strong performance across downstream benchmarks, Tabula reveals combinatorial regulatory logic across diverse biological systems, including hematopoiesis, pancreatic endogenesis, neurogenesis, and cardiogenesis. Using a new scRNA-seq dataset of paired young and aged human fibroblasts, Tabula nominates rejuvenation factors through age- and identity score-guided in silico prioritization, outperforming conventional approaches. Thus, Tabula represents an important advance in single-cell foundation modeling by integrating tabular learning with FL, paving the way toward privacy-preserving virtual cells for human health.", "url": "https://wpnews.pro/news/predictive-single-cell-foundation-model-for-gene-regulation-and-aging-with", "canonical_source": "https://arxiv.org/abs/2607.19400", "published_at": "2026-07-23 04:00:00+00:00", "updated_at": "2026-07-23 04:13:32.274873+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "ai-research", "ai-ethics", "ai-infrastructure"], "entities": ["Tabula", "Chiron", "arXiv"], "alternates": {"html": "https://wpnews.pro/news/predictive-single-cell-foundation-model-for-gene-regulation-and-aging-with", "markdown": "https://wpnews.pro/news/predictive-single-cell-foundation-model-for-gene-regulation-and-aging-with.md", "text": "https://wpnews.pro/news/predictive-single-cell-foundation-model-for-gene-regulation-and-aging-with.txt", "jsonld": "https://wpnews.pro/news/predictive-single-cell-foundation-model-for-gene-regulation-and-aging-with.jsonld"}}
