SpatioEv: Spatial evolution of protein and morphological features reveals development dynamics of cells and spatial neighbourhoods

Understanding cellular function in tissues demands sophisticated tools to decode complex microenvironmental interactions. Current spatial analysis methods often lack the comprehensive framework needed to systematically analyse cell morphology, dynamics, interactions, and extracellular matrix (ECM) architecture. We introduce SpatioEv, a unified computational framework for highly multiplexed tissue imaging that addresses these critical gaps. SpatioEv integrates automated quality control, cell phenotyping, neighbourhood identification, multi-scale spatial characterization, niche boundary analysis, ECM fiber-cell interaction mapping, and spatiotemporal trajectory inference. This pipeline enables reproducible cell annotation, reveals novel ECM-cell interactions, characterizes tissue neighbourhood boundaries, and infers developmental progressions directly from spatial data. Using this, we can identify disease-specific spatial signatures distinguishing rheumatoid arthritis from osteoarthritis, characterize diverse tumour boundary phenotypes in cancer metastases in liver, and map evolutionary trajectories in pancreatic ductal adenocarcinoma (PDAC) at single-niche resolution. Our findings highlight the significance of spatial context in shaping cell behaviour and underscore its potential to uncover emergent tissue architecture and cellular dynamics. By addressing major analytical challenges, SpatioEv provides a scalable, adaptable platform for advancing spatial biology and translational research.

Ex vivo Model of Functioning Human Lymph Node Reveals Pivotal Role for Innate Lymphoid Cells and Stromal Populations in Response to Vaccine Adjuvant

Immunological processes that underpin the administration of therapeutics and vaccines are poorly defined due to a lack of models which faithfully recapitulate human immune responses. Inbred mice lack the diversity inherent to people, while the microanatomical organisation of human tissue is lost in isolated cell suspensions. We describe precision-cut human lymph node (LN) slices as architecturally-preserved, functioning lymphoid tissue model system, and explore early inflammatory responses to a potent vaccine liposomal adjuvant containing a TLR4-agonist and QS21 saponin. Combining scRNA-seq, multiplexed immunofluorescence and secretome analysis, we dissect direct and indirect signalling pathways in both leukocytes and stromal cells to reveal communication networks linking innate and adaptive immunity. Application of molecular inhibitors reveals that secretion of IL-1{beta}, but not IL-18, is TLR4-dependent in human LN. Retaining donor-to-donor immune variation, this ex vivo LN model system enables the study of pathways previously difficult to observe in humans, paving the way towards precision medicine.
