Head and neck squamous cell carcinoma (HNSCC) is a very heterogeneous cancer with a poor overall response to therapy.

Tumor cell heterogeneity represents hurdles for therapeutic elimination of CSCs. https://www.roneverhart.com/Plastic-Gift-Boxes-Gold-5X4X3-5-6-Pack-Bakery-Boxes-With-Base-Lid-Ribbon/
