Even though CD8+ T cell proliferation was noticeably augmented by the adherent SCLC populations (with H82Adh, 80.37 ± 5.82%; H69Adh, 90.07 ± 2.55%; H69Sc, 90.56 ± 1.85%), induced proliferation was also found in the co-cultures with parental SCLC cell lines, especially with NCI-H69 (65.15 ± 6.05%) and NCI-H82 (71.58 ± 6.7%) (Fig. 2c, Supplementary Fig. 7). Here, CD8A is linked to small cell lung carcinoma.
