Figure Lengend Snippet: A For prostate cancer (left) and testicular cancer (right), UMAP and t-SNE dimensional reduction analysis reveal different cell subpopulations. B Single-cell expression localization of genes of CHMP4C. C Single-cell expression localization of genes of HLA-DQA1. D Single-cell expression localization of genes of RAB29. The upper and lower plots correspond to the single-cell expression distribution in prostate cancer and testicular cancer, respectively. The color gradient reflects gene expression levels (blue for low, green for high). UMAP, uniform manifold approximation and projection; t-SNE, t-distributed stochastic neighbor embedding. For PCa, dimensionality reduction was used with UMAP; for TC, t-SNE was chosen for a better fit.
