Brain tumors' severity ranges from benign to highly aggressive and invasive. Bioengineering
tools can assist in understanding the pathophysiology of these tumors from outside the body
and facilitate development of suitable antitumoral treatments. Here, we first describe the
physiology and cellular composition of brain tumors. Then, we discuss the development of
three-dimensional tissue models utilizing brain tumor cells. In particular, we highlight the
role of hydrogels in providing a biomimetic support for the cells to grow into defined …
