Patent number: 11885732Abstract: A classification training method for training classifiers adapted to identify specific mutations associated with different cancer including identifying driver mutations. First cells from mutation cell lines derived from conditions having the number of driver mutations are acquired and 3D image feature data from the number of first cells is identified. 3D cell imaging data from the number of first cells and from other malignant cells is generated, where cell imaging data includes a number of first individual cell images. A second set of 3D cell imaging data is generated from a set of normal cells where the number of driver mutations are expected to occur, where the second set of cell imaging data includes second individual cell images. Supervised learning is conducted based on cell line status as ground truth to generate a classifier.Type: GrantFiled: October 18, 2022Date of Patent: January 30, 2024Assignee: VisionGate, Inc.Inventors: Michael G.

Patent number: 11369966Abstract: A multi-layer sealing structure for sealing a microwell array defined in or on a substrate includes at least one front compliant layer, a back compliant layer, and a flexural layer arranged between the at least one front compliant layer and the back compliant layer, wherein the at least one front compliant layer is closer than the back compliant layer to microwells of the microwell array. One or more front compliant layers may be optically reflective and/or may embody a sensor layer. The back compliant layer may include an adhesive or various types of rubber, and the flexural layer may include a polymeric material or metal. A multi-layer sealing structure may be separated from a microwell array by peeling. A multi-layer sealing structure allows local disruption of sealing where particle contaminants are present without compromising the sealing performance of an entire microwell array, and without requiring a large sealing force.Type: GrantFiled: September 16, 2016Date of Patent: June 28, 2022Assignee: Arizona Board of Regents on Behalf of Arizona State UniversityInventors: Clifford Anderson, Kristen Lee, Jacob Messner, Laimonas Kelbauskas, Benjamin Ueberroth, Yanqing Tian, Deirdre Meldrum

Patent number: 11136614Abstract: Methods for seeding live cells onto spatially defined regions of a substrate including multiple features (e.g., microwells or other microenvironments) utilize a stencil embodied in a hole-defining sacrificial film. A sacrificial film devoid of holes may be applied over features of a substrate, and a hole generating mechanism (e.g., hot needle or laser) aligned with features may be used to define holes in the film. Alternatively, holes may be predefined in a sacrificial film to form a stencil, and the stencil may be assembled to the substrate with the holes registered with features thereof. Thereafter, cells are seeded through holes in the film. Seeded cells are subject to incubation, further processing, and/or performance of one or more assays, and the hole-defining sacrificial film (stencil) may be removed.Type: GrantFiled: October 7, 2016Date of Patent: October 5, 2021Assignee: Arizona Board of Regents on Behalf of Arizona State UniversityInventors: Jacob Messner, Clifford Anderson, Honor Glenn, Kristen Lee, Mark Richards, Laimonas Kelbauskas, Kimberly Bussey, Deirdre Meldrum

Patent number: 11045807Abstract: An integrated technological platform enabling real-time quantitative multiparameter metabolic profiling, utilizing either or both of extra and intracellular optical sensors, individually or simultaneously. A scalable embedded micropocket array structure, generally fabricated on fused silica substrates, facilitates the integration of multiple, spatially separated extracellular sensors for multiparameter analysis in a container formed with the use of an activation mechanism forming part of a device configured to hold the container during the measurements. The creation of hermetically sealed microchambers is carried out with a pneumatically and/or mechanically and/or electromechanically driven device that is “floating” within the holding device and that is optionally equipped with a vacuum/suction mechanism to hold a component of the container at its surface.Type: GrantFiled: February 26, 2018Date of Patent: June 29, 2021Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: Deirdre Meldrum, Laimonas Kelbauskas, Yanqing Tian, Honor Glenn, Clifford Anderson, Kristen Lee, Ganquan Song, Liqiang Zhang, Jeff Houkal, Fengyu Su, Benjamin Ueberroth, Jacob Messner, Hong Wang, Kimberly Bussey

Patent number: 10940476Abstract: A device for high-throughput multi-parameter functional profiling of the same cells in multicellular settings and in isolation is provided. In certain aspects, an integrated microfluidic device for multi-parameter metabolic and other phenotypic profiling of live biological cells is useable with: 1) multicellular clusters or small biopsy tissue samples, 2) cultures of the constituent cells obtained after cluster/tissue dissociation, and 3) the same constituent single cells in isolation. The approach enables study of the effects of multicellular complexity, such as in response to treatment, pathogens, stress, or other factors concerning disease origination and progression. Measurements may be performed on single cells or multicellular populations or tissues in the same assay at the same time.Type: GrantFiled: April 21, 2017Date of Patent: March 9, 2021Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: Laimonas Kelbauskas, Honor Glenn, Jeff Houkal, Clifford Anderson, Yanqing Tian, Fengyu Su, Deirdre Meldrum

Publication number: 20200178967Abstract: A thixotropic and biocompatible gel, formed by combining of 4-arm polyethylene glycol with fumed silica (PEG-silica). The thixotropicity of the gel is affected by the ratio of PEG to silica. To study the gels biocompatibility, the cell suspension in PBS or another medium was added to the PEG-silica gel via mixing to uniformly disperse the cells in the gel and then placed in an incubator before performing fluorescence live-dead assays. Duration of cell viability (cell life time) in gels was measured to be up to several days, depending on gel composition. Due to their optical and fluidic properties the gels are compatible with live cell imaging including 3D computed tomography and offer a means for moving the cells in a highly controllable manner by applying and removing pressure on the gels.Type: ApplicationFiled: August 29, 2018Publication date: June 11, 2020Inventors: Deirdre Meldrum, Fengyu Su, Laimonas Kelbauskas, Vivek Nandakumar, Yanqing Tian, Roger Johnson
