“…Cancer stem cells (CSC) are a small subpopulation of cancer cells with self‐renewal potential, capable of maintaining tumor growth and cell differentiation, involved in metastatic process, recurrence, and resistance to chemotherapeutic agents, 1 and may be the main source of cancer invasion, migration and extensive metastasis, , 2,3 laryngeal squamous cell carcinoma in the second rank of head and neck squamous cell carcinoma; tumor stem cells (CSC) play a key role in the development and progression of head and neck squamous cell carcinoma (HNSCC), and can result tumor growth and malignant behavior 4 . Laryngeal cancer stem cells can be isolated from laryngeal squamous cell carcinoma tissue, and laryngeal cancer stem cells can be used to study the occurrence, development, and treatment strategies of laryngeal cancer, the most common CSCs markers are CD44, CD24, CD133, and ALDH1A1 5 . Previous studies by our group have demonstrated that CD133 is one of the markers of tumor initiating cells in the human laryngeal cancer Hep‐2 cell line, 6 CD133 positive cells have a significant ability to generate new tumors in vivo 7 with stemness phenotype characteristics, 8 and CD133+ laryngeal cancer stem cells have stronger invasive, migratory, and tumorigenic abilities compared with normal laryngeal cancer stem cells 9 .…”
