Spatial biology is a scientific discipline that examines the spatial organization and interactions of cells, genes, and molecules within an organism. This field has advanced to provide a comprehensive understanding of the three-dimensional architecture of cells, tissues, and organs in biological systems. This discipline utilizes microscopy, bioinformatics, and advanced biotechnological methods to examine biological processes in greater detail and from a broader perspective. It has significant applications in fields such as cancer research, neuroscience, developmental biology, and immunology.
