This discipline originated about twenty-five years ago but is gaining traction in recent times, with the journal Nature Methods naming spatial proteomics as its method of the year in 2024. Spatial biology brings spatial context to molecular-level understanding, allowing researchers to simultaneously examine tissue structure and cellular composition. This dual focus defines the approach of spatial biology to address some of the most pressing questions in biology today.
Traditional bulk or single-cell approaches use tissue or cell samples that are lysed into solutions, with no scope for preserving either tissue architecture, or cellular microenvironments, both of which can affect disease states and immune responses drastically. However, in spatial biological approaches, the architectural integrity of tissues is maintained, enabling the mapping of gene expression, protein localization, and cellular interactions within their native microenvironments. This comprehensive approach generates multi-modal data, which is computationally challenging to translate into meaningful insights. Overcoming these challenges is crucial for understanding immune system dynamics, tumor heterogeneity, and tissue remodeling during disease progression. These insights drive progress in personalized medicine, biomarker discovery, and therapeutic targeting, making spatial biology essential for modern biopharma research.
