FOLH1 and fibrosarcoma: CJ215 was taken up and delineated multiple preclinical solid tumor lines including breast (4T1, murine derived), prostate (PC3-PSMA, human derived), colon (CT26, murine derived), fibrosarcoma (HT1080, human derived) and finally, intraperitoneal colorectal cancer (SW1222, human derived).27–30 These models represent some of the most prevalent and fatal tumors, where surgery will be a primary a treatment option (with or without adjuvant chemo/radiation therapy).31–35 CJ215 tumor uptake could be detected with both SWIRFI and NIRFI.
