Three-dimensional in vitro models in head and neck cancer: current trends and applications.

Abstract

Head and neck cancer (HNC) is the sixth most prevalent malignancy worldwide and includes a variety of upper gastrointestinal abnormalities. HNC includes oral, throat, voice box, nasal cavity, paranasal sinuses, and salivary gland cancers. Squamous cells in the mouth, nose, and throat cause HNC. Drugs, alcohol, poor diets, smoking, and genetics all contribute to this condition. Cancer research has focused on three-dimensional (3D) models in HNC biology in recent decades. An adequate microenvironmental system and cancer cell culture are the initial steps to understanding cancer cells' complicated interactions with their surroundings. New 3D models claim to bridge in vivo and in vitro investigations and erase the gap. Interdisciplinary cell biology and tissue engineering researchers are creating 3D cancer tissue models to better understand the illness and develop more accurate cancer medicines. Tissue engineering researchers, who are always exploring novel approaches to treat cancer, have been able to include the third dimension into laboratory settings and mimic cell-to-cell and cell-to-matrix interactions by recreating the tumor microenvironment using 3D models and so make research on cancer easier. This review addresses recent developments in tissue engineering with an emphasis on 3D models in HNC.
