Second, in an independent cohort of 10 in vitro cultured patient-matched normal and tumor fibroblasts, isolated and purified by fluorescence-activated cell sorting from patients with gastric cancer (46), we confirmed INHBA upregulation (P = 0.023) in tumor fibroblasts, along with increased FAP (P = 0.027; Fig. 4H). Here, INHBA is linked to neoplasm.
