# Cell Biology

> Cell biology examines the fundamental unit of life—the cell—with molecular, genetic, and imaging tools to understand how cellular components are organized, how cells divide, communicate, and maintain homeostasis. Modern proximity labeling techniques like BioID map the spatial proteome of organelles with unprecedented comprehensiveness, while genome-wide CRISPR screens identify genes essential for specific cellular processes. Dysfunction in cell biological processes underlies virtually every disease, from cancer (uncontrolled proliferation) to neurodegeneration (protein aggregation and organelle dysfunction). The field drives discovery in developmental biology, immunology, and regenerative medicine.
