A window into the changing tumor microenvironment

A window into the changing tumor microenvironment

Researchers led by Ludwig Lausanne’s Anoek Zomer, Davide Croci and Johanna Joyce described in a June publication in iScience their development of a multimodal imaging platform to explore, over extended periods, the changing interactions between various components of the brain tumor microenvironment (TME) in mice.

To capture these cellular and molecular interactions as they occur in the brain TME, Joyce and her colleagues developed an imaging platform that combines magnetic resonance imaging with high-resolution two-photon intravital microscopy, which enables observation of the behavior of individual cells in living animals. They integrated into this platform powerful data science tools for single cell imaging analysis and applied this multifaceted system to track the changing behavior of hundreds of thousands of individual cells in the same animal models over several weeks, capturing an extremely detailed portrait of the changing TME during cancer progression.
