Immunosequencing reveals a homogeneous distribution of TILs. The TCRB repertoire is highly homogeneous over the mass of the metastatic tumor site (orange). Also, the overlap between the metastatic site and the primary tumor (green) and is much higher than that between the tumor and a paired blood sample (blue). Adapted from Emerson et al.
