Article Title: Spatial transcriptomics of urothelial carcinoma with basal/squamous differentiation identifies Galectin-7 as a specific marker of squamous lineage commitment
doi: 10.1007/s12672-026-04927-z
Figure Lengend Snippet: LGALS7 is selectively expressed in Ba/Sq differentiation and promotes squamous carcinoma cell proliferation. A The H&E image from Fig. B is shown again, with a red box indicating the region analyzed in this figure. Spatial transcriptomic maps display TP63 and LGALS7 expression patterns within the boxed region, corresponding to the UC–Ba/Sq interface. B Cluster-level expression of TP63 and LGALS7. C Immunohistochemistry (IHC) of the cystectomy specimen showing diffuse p63 positivity in both urothelial carcinoma (UC) and Ba/Sq-differentiated tumor components, and selective Galectin-7 expression restricted to Ba/Sq-differentiated tumor nests. Scale bars, 1 mm. D Western blot showing Galectin-7 expression across cancer cell lines (left), and immunofluorescence (IF) of SCaBER cells showing cytoplasmic localization (right). E Proliferation assay of SCaBER cells following LGALS7 knockdown
Article Snippet: To assess the diagnostic performance of Galectin-7 in identifying squamous differentiation within urothelial carcinoma (UC), we performed immunohistochemical (IHC) analysis on 28 cases of Ba/Sq UC and 64 cases of pure UC.
