Bioengineering the ameloblastoma tumour to study its effect on bone nodule formation

Scientific Reports, 2021
Ameloblastoma is a benign, epithelial cancer of the jawbone, which causes bone resorption and disfigurement to patients affected. The interaction of ameloblastoma with its tumour stroma drives invasion and progression.
