Patent number: 11701657Abstract: A column-based device and method for retrieving cells of interest were enclosed. The said device comprises a column comprising (i) an inner wall defining an inner chamber with inlet and outlet openings, (ii) a perforated plug disposed adjacent to the outlet opening, (iii) a sleeve insert with a channel and disposed within the chamber and adjacent to the perforated plug, and (iv) a filtering means housed within sleeve insert sandwiched between two sealing means. In particular, Tumor-derived endothelial cell clusters (TECCs) as characterized multiple nuclei, expression of endothelial markers (PECAM1, VWF and CDH5), and non-expression of leukocyte, megakaryocyte and platelets markers, may be retrieved using the disclosed device. Also encompassed are methods, reagents and kits for the diagnosis and prognosis of cancers by detecting for the presence of TECCs isolated from blood samples using the claimed device.Type: GrantFiled: October 22, 2020Date of Patent: July 18, 2023Assignee: AGENCY FOR SCIENCE, TECHNOLOGY AND RESEARCHInventors: Jackie Y.
