Novel triple‑positive markers identified in human non‑small cell lung cancer cell line with chemotherapy-resistant and putative cancer stem cell characteristics.

ABSTRACT: Through the specific identification and direct targeting of cancer stem cells (CSCs), it is believed that a better treatment efficacy of cancer may be achieved. Hence, the present study aimed to identify a CSC subpopulation from adenocarcinoma cells (A549) as a model of non‑small cell lung cancer (NSCLC). Ιnitially, we sorted two subpopulations known as the triple‑positive (EpCAM+/CD166+/CD44+) and triple‑negative (EpCAM-/CD166-/CD44-) subpopulation using fluorescence-activated cell sorting (FACS). Sorted cells were subsequently evaluated for proliferation and chemotherapy-resistance using a viability assay and were further characterized for their clonal heterogeneity, self-renewal characteristics, cellular migration, alkaline dehydrogenase (ALDH) activity and the expression of stemness-re
