摘要
Purpose: To investigate the effect of cisplatin on the growth and metastasis abilities of lung cancer stem cells (CSCs) via molecular imaging. Materials and Methods: The expression changes of lung CSCs cellmarker in A549-Luc- C8 human non-small-cell lung cancer (NSCLC) cell line with or without cisplatin treatment were detected by flow cytometry. The tumorigenesis and metastasis abilities of A549-Luc-C8 cells were monitored both in vitro and in vivo, and the mechanism was assessed by gene sequencing. Results: About 1%-2% of CSCs were detected in A549-Luc-C8 cells and decreased CSCs percentage was observed after cisplatin treatment. Attenuated tumorigenesis and metastasis abilities of A549-Luc-C8 cells were found in cisplatin treated group. Conclusions: Decreased percentage of CSCs in A549-Luc-C8 cells can be induced by cisplatin treatment, which may partly be attributed to the attenuated expression of growth factors.
