High resolution 3D imaging of primary and secondary tumor spheroids using multicolor multi-angle Light Sheet Fluorescence Microscopy (LSFM)

Breast cancer and Glioblastoma brain cancer are aggressive malignancies with poor prognosis. In this study primary Glioblastoma and secondary breast cancer spheroids are formed and treated with the well-known Temozolomide and Doxorubicin chemotherapeutics, respectively. A custom multi-angle Light Sheet Fluorescence Microscope is employed for high resolution imaging of both cancer cell spheroids. Such a technique is successful in realizing pre-clinical drug screening, while enables the discrimination among physiologic tumor parameters. LSFM technique, parameters and method followed are also presented.
