Article Abstract
Spatial transcriptomics (ST) has advanced our understanding of tissue regionalization by enabling the visualization of gene expression within whole-tissue sections, but current approaches remain plagued by the challenge of achieving single-cell resolution without sacrificing whole-genome coverage. Here we present Spotiphy (spot imager with pseudo-single-cell-resolution histology), a computational toolkit that transforms sequencing-based ST data into single-cell-resolved whole-transcriptome images. Spotiphy delivers the most precise cellular proportions in extensive benchmarking evaluations. Spotiphy-derived inferred single-cell profiles reveal astrocyte and disease-associated microglia regional specifications in Alzheimer's disease and healthy mouse brains. Spotiphy identifies multiple spatial domains and alterations in tumor-tumor microenvironment interactions in human breast ST data. Spotiphy bridges the information gap and enables visualization of cell localization and transcriptomic profiles throughout entire sections, offering highly informative outputs and an innovative spatial analysis pipeline for exploring complex biological systems.

B cells located in tertiary lymphoid structures (TLSs) may undergo clonal expansion, somatic hypermutation, isotype switching, and tumor-specific antibody production, suggesting that antibody-producing plasma cells may be involved in antitumor immunity. This study used a combination of single-cell sequencing (five samples from our center, and four samples from PRJNA662018) and spatial transcriptome (one sample from our center, and four samples from GSE169379) research methods to investigate the relationship between TLSs and the immunoglobulin repertoire in muscle invasive bladder cancer (MIBC). 405 patients with MIBC from TCGA and 348 patients with metastatic urothelial carcinoma on PD-L1 inhibitor treatment from the IMvigor210 trial were included in this study.

Studies have reported the special value of PANoptosis in cancer, but there is no study on the prognostic and therapeutic effects of PANoptosis in bladder cancer (BLCA). This study aimed to explore the role of PANoptosis in BLCA heterogeneity and its impact on clinical outcomes and immunotherapy response while establishing a robust prognostic model based on PANoptosis-related features. Gene expression profiles and clinical data were collected from public databases.
