Patent number: 12201977Abstract: 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: August 18, 2021Date of Patent: January 21, 2025Assignees: THE JOHNS HOPKINS UNIVERSITY, UNIVERSITY OF MARYLAND, BALTIMORE OFFICE OF RESEARCH AND DEVELOPMENTInventors: Konstantinos Konstantopoulos, Colin Dowlin Paul, Alfredo Quinones-Hinojosa, Aikaterini Kontrogianni-Konstantopoulos

Patent number: 9739784Abstract: Provided herein are methods and kits for evaluating potential for invasiveness, metastasis, or recurrence of an epithelial cell cancer. In the methods the expression profile of giant obscurins is detected in a tissue sample of tumor cells or suspected tumor cells and assessed for giant obscuring expression level and distribution therein. Decreased levels or altered distribution of giant obscurins in the cells compared to a control non-invasive standard or to a sample taken at a different point in time is indicative of increased potential of at least one of the invasiveness, metastasis, or recurrence of the epithelial cell cancer. The kit comprises a detection reagent suitable for detecting the presence and distribution of giant obscurins or an amount of the gene product(s) encoding giant obscurins in cells of a tissue sample and instructions for using the detection reagent.Type: GrantFiled: March 21, 2014Date of Patent: August 22, 2017Assignees: UNIVERSITY OF MARYLAND, BA, JOHNS HOPKINS UNIVERSITYInventors: Aikaterini Kontrogianni-Konstantopoulos, Konstantinos Konstantopoulos, Marey Shriver, Nicole Perry

Publication number: 20120100560Abstract: Applications in nanomedicine, such as diagnostics and targeted therapeutics, rely on the detection and targeting of membrane biomarkers. The present invention, in one embodiment, utilizes quantitative profiling, spatial mapping, and multiplexing of cancer biomarkers using functionalized quantum dots. This approach provides highly selective targeting molecular markers for pancreatic cancer with extremely low levels of non-specific binding and provides quantitative spatial information of biomarker distribution on a single cell, which is important since tumors cell populations are inherently heterogeneous. The quantitative measurements (number of molecules per square micron) is validated using flow cytometry and demonstrated using multiplexed quantitative profiling using color-coded quantum dots.Type: ApplicationFiled: July 25, 2011Publication date: April 26, 2012Applicant: The Johns Hopkins UniversityInventors: Peter C.
