This review article discusses the rapidly evolving field of spatial transcriptomics (ST), which enables the quantification of RNA across the transcriptome within intact tissue sections, overcoming the historical trade-off between broad biomolecule measurement ('-omics') and targeted localization (e.g., immunostaining). The authors categorize ST into two main methodologies: sequencing-based ST (sST...

This article focuses on how mitochondrial activity influences the resilience of nociceptors, or pain-sensing neurons, against excitotoxicity, which is cell death caused by overexcitation and calcium overload. Through a genome-wide screen, the authors identified that the electron transport chain (ETC) is a key determinant of cellular protection. Lowering ETC expression or activity enhances resilien...

This article introduces a novel technique called three-dimensional cyclic immunofluorescence (3D CyCIF) for high-plex, high-resolution imaging of cell states and immune niches within human tumor tissues. The authors demonstrate that traditional thin tissue sections, typically 5 µm thick, result in fragmented cells and inaccurate phenotyping, whereas sections eightfold to tenfold thicker (30–40 µm)...

This paper introduce a new visual-omics foundation model called OmiCLIP, designed to integrate histopathology images and spatial transcriptomics data for computational biology. OmiCLIP was trained on a curated dataset, ST-bank, which consists of over two million paired tissue images and transcriptomic data across 32 organs, by converting gene expression into "sentences" for language model processi...

By consuming over 20,000 G...

This paper describes a new computational model called Topological Velocity Inference (TopoVelo), designed to jointly infer the spatial and temporal dynamics of cell fate transitions using spatial transcriptomic data. TopoVelo significantly advances existing RNA velocity frameworks by integrating spatial coupling among cells, modeling the entire tissue's dynamics through spatially coupled different...

This article presents a study utilizing spatial transcriptomics (Stereo-seq) to investigate the heterogeneity and developmental states of tertiary lymphoid structures (TLSs) in hepatocellular carcinoma (HCC) patients.

This paper introduces MintFlow, a novel generative AI algorithm designed for mapping and reprogramming human tissue microenvironments using spatial transcriptomics data. MintFlow's core innovation is its ability to disentangle intrinsic cellular characteristics from gene expression changes induced by the local microenvironment, moving beyond purely descriptive spatial analysis. Applied to human di...

This paper details how macropinocytosis—a cellular process for scavenging extracellular fluids—is crucial for maintaining the identity of myofibroblasts (myCAFs), a subtype of cancer-associated fibroblasts (CAFs), in pancreatic cancer, specifically under glutamine stress. The authors, Zhang et al., demonstrate that inhibiting macropinocytosis in CAFs forces a shift from myCAFs to the inflammatory...

The article introduces TriPath, a deep-learning platform designed for the analysis of three-dimensional (3D) pathology samples to predict clinical outcomes, specifically patient prognostication for prostate cancer recurrence.
