Violin plots of populations of interest for measured parameters. This shows the general trend for upregulation of immune checkpoint receptors on the TIL populations, as well as the heterogeneity of the tumor populations in specific markers, particularly PD-1, PD-L1, FasR, TIGIT, and HLA-DR. *P < .05; **P < .01; ***P < .001; ****P < .0001.
