Welcome to Human Ocular Single-Cell Atlas (HOSCA)

The human eye is a highly specialized organ composed of diverse tissues, each with unique cellular microenvironments that are crucial for vision. Recent advancements in single-cell RNA sequencing (scRNA-seq) have provided unprecedented opportunities to explore the cellular heterogeneity of ocular tissues and diseases. Human Ocular Single-Cell Atlas (HOSCA) is an atlas-scale curated database that integrates and harmonizes over 3.88 million single-cell transcriptomic profiles spanning 16 ocular anatomical regions and 15 associated diseases from 704 human samples and 60 high-quality scRNA-seq datasets. As the largest ocular single-cell resource to date, HOSCA bridges the gap between atlas-scale data and precision ophthalmology and provides a powerful platform for advancing our understanding of ocular biology and diseases.
