Cancer stem cells (CSCs) have been characterized by several exclusive features that include differentiation, self-renew, and homeostatic control, which allows tumor maintenance and spread. Recurrence and therapeutic resistance of head and neck squamous cell carcinomas (HNSCC) have been identified to be attributed to CSCs. However, the biomarkers led to the development of HNSCC stem cells remain less defined. In this study, we quantified cancer stemness by mRNA expression-based stemness index (mRNAsi), and found that mRNAsi indices were higher in HNSCC tissues than that in normal tissue. A significantly higher mRNAsi was observed in HPV positive patients than HPV negative patients, as well as in male patients than in female patients. The 8-mRNAsi signature was identified from the genes in two modules which were mostly related to mRNAsi screened by weighted gene co-expression network analysis. In this prognostic signatures, high expression of RGS16, LYVE1, hnRNPC, ANP32A, and AIMP1 focus in promoting cell proliferation and tumor progression. While ZNF66, PIK3R3, and MAP2K7 are associated with a low risk of death. The riskscore of eight signatures have a powerful capacity for 1-, 3-, 5-year of overall survival prediction (5-year AUC 0.77, 95% CI 0.69–0.85). These findings based on stemness indices may provide a novel understanding of target therapy for suppressing HNSCC stem cells.

Neck Squamous Cell Carcinoma

: Head and Neck Squamous Cell Carcinoma (HNSCC) is categorized as the sixth most common cancer worldwide, with an incidence of more than 830,000 cases per year and a mortality rate of 50%. Tobacco use, alcohol consumption, and Human Papillomavirus infection are the prominent risks for HNSCC. Despite significant developments in the treatment of HNSCC, a high rate of recurrences makes the clinical situation worse and results in poor survival rates. Recent perspectives demonstrate that whereas epithelial transformation plays a crucial role in cancer development, tumor surrounding microenvironment takes part in progression of cancer as well. Cancer Stem Cells (CSCs), which harbor unlimited self-renewal capacity, have a crucial role in the growth of HNSCC and this cell population is responsible for tumor recurrence unless eliminated by targeted therapy. CSCs are not only a promising target for tumor therapy, but also a crucial biomarker to determine the patients at high risk for undetermined results and disease development. Just as the bone marrow which is the niche of hematopoietic and mesenchymal stem cells, is important for stem cells maintenance. Similarly, the concept of microenvironment is also important for the maintenance of CSCs. Apart from the cell-cell interactions, there are many parameters in the cancer microenvironment that affect the development of cancer, such as extracellular regulation, vascularization, microbial flora, pH and oxygenation. The purpose of this review is to introduce HNSCC, explain the role of CSCs and their microenvironment and refer to the conventional and novel targeted therapy for HNSCC and CSCs.

Abstract Head and neck squamous cell carcinoma (HNSCC) has a poor 5-year survival rate of 50%. One potential reason for treatment failure is the presence of cancer stem cells (CSCs). Several cell markers, particularly CD44, have been used to isolate CSCs. However, isolating a pure population of CSC in HNSCC still remains a challenging task. Recent findings show that normal oral stem cells were isolated using CD271 as a marker. Thus, we investigated the combined use of CD271 and CD44 to isolate an enriched subpopulation of CSCs, followed by their characterization in vitro, in vivo, and in patients’ tissue samples. Fluorescent-activated cell sorting was used to isolate CD44+/CD271+ and CD44+/CD271− from two human HNSCC cell lines. Cell growth and self-renewal were measured with MTT and sphere/colony formation assays. Treatment-resistance was tested against chemotherapy (cisplatin and 5-fluorouracil) and ionizing radiation. Self-renewal, resistance, and stemness-related genes expression were measured with qRT-PCR. In vivo tumorigenicity was tested with an orthotopic immunodeficient mouse model of oral cancer. Finally, we examined the co-localization of CD44+/CD271+ in patients’ tissue samples. We found that CD271+ cells were a subpopulation of CD44+ cells in human HNSCC cell lines and tissues. CD44+/CD271+ cells exhibited higher cell proliferation, sphere/colony formation, chemo- and radio-resistance, upregulation of CSCs-related genes, and in vivo tumorigenicity when compared to CD44+/CD271− or the parental cell line. These cell markers showed increased expression in patients with the increase of the tumor stage. In conclusion, using both CD44 and CD271 allowed the isolation of CSCs from HNSCC. These enriched CSCs will be more relevant in future treatment and HNSCC progression studies.
