Patent number: 11559803Abstract: The present invention describes an integrated apparatus that enables identification of migratory cells directly from a specimen. The apparatus only requires a small number of cells to perform an assay and includes novel topographic features which can reliably differentiate between migratory and non-migratory cell populations in a sample. Both the spontaneous and chemotactic migration of cancer cells may be measured to distinguish between subpopulations within a tumor sample. The migratory cells identified using the apparatus and methods of the present invention may be separated and further analyzed to distinguish factors promoting metastasis within the population. Cells in the apparatus can be treated with chemotherapeutic or other agents to determine drug strategies to most strongly inhibit migration. The use of optically transparent materials in some embodiments allows a wide range of imaging techniques to be used for in situ imaging of migratory and non-migratory cells in the apparatus.Type: GrantFiled: September 7, 2018Date of Patent: January 24, 2023Assignees: UNIVERSITY OF MARYLAND, BALTIMORE, THE JOHNS HOPKINS UNIVERSITYInventors: Konstantinos Konstantopoulos, Colin Dowlin Paul, Alfredo Quinones-Hinojosa, Aikaterini Kontrogianni-Konstantopoulos
