Although no formal validation of FOLR1 as an LSC marker has been undertaken, preclinical modeling of STRO-002, an antibody-drug conjugate (ADC) against FOLR1 [126] and, separately, a FOLR1-specific chimeric antigen receptor T cell (CAR-T) [127], showed promising anti-tumor efficacy. This evidence concerns the gene FOLR1 and neoplasm.
