(A) Percentage of cells expressing CEACAM5, Trop2, PSMA, and PSCA, and (B) staining intensity from mIF of ARPC (n=70), NEPC (n=20), DNPC (n=14), and AMPC (n=3) tissue cores. (C) Co-expression of PSMA and PSCA in Trop2+ cells per core. (D) Co-expression of Trop2, PSMA, and PSCA in CEACAM5+ cells per core. (E) Quantitative single-cell mIF signal intensities of proteins (rows) in cells from ARPC (n=655,676) and (F) NEPC cores (n=113,509). Error bars represent ± SD. * p<0.05; ** p<0.01; *** p<0.001; **** p<0.0001. Kruskal-Wallis p values are shown for plots A-D. Pearson correlation coefficient (r) and P values for each measured protein is shown numerically next to heatmap rows.
