The Spatial Atlas of Human Anatomy (SAHA) is a groundbreaking initiative to create the most detailed, multimodal spatial map of the healthy human body ever assembled. By capturing spatial omics data across diverse individuals—spanning age, gender, and ancestry—SAHA reveals how genes, proteins, cells, and tissues are organized and interact in their native environment. This comprehensive reference is designed to advance our understanding of human biology, improve diagnostics, and accelerate discoveries in precision medicine.
