Cellular Particle Exclusion Assay

Cellular matrix production is crucial in the formation, maintenance, and repair of organs and tissues. While there are many dyes and antibodies available to study matrix production in-vitro, such reporters can generally only be applied as an endpoint tool as they require cell fixation and do not support live cell study.

Gene Therapy R&D

Genetic transfection of cell types to elucidate pathways involved in specific pathologies requires ongoing assessment of transfection efficiencly to ensure that modification was successful and subsequent assays performed are valid.

Colony Analysis

Undifferentiated embryonic stem cells and induced pluripotent stem cells will form aggregates or "colonies" in vitro prior to differentiation. Evaluation of colony shape, area, cell density, rate of growth/proliferation, migration, etc. can be important factors in selection of an appropriate cells for subsequent differentiation and expansion for transplantation or bioassay development.

MEMs Cell Sorting

In order to assess the ability of a MEMs device under a magnetic field to sort cells tagged with metallic markers, a customized set of algorithms was developed to automatically segment and count cells in time-lapse videos.

Cell Proliferation/Lineage Analysis

Cellular division and lineage tracing analysis is an extremely complex problem with respect to image analysis but essential for cell fate assessment and phenotyping following genetic manipulation or drug treatment.

Filopodial and Ruffle Analysis

Images of live endothelial cells seeded subconfluently on a glass-bottom dish were acquired every 3 minutes over 160 minutes using DIC imaging on an inverted wide-field microscope.

Confocal Time-Lapse Imaging of Actin Ruffles

Mechanics of endothelial cell (EC) migration have been extensively studied to elucidate mechanisms/pathways involved wound healing and neovascularization. It is widely accepted that actin, a major cytoskeletal component, plays a crucial role EC translocation.

Cell Migration Tracking Analysis

Endothelial cell (EC) migration is a vital process in wound healing, tissue maintenance, and neovascularization. As such, a number of in-vitro migration assays are available to assess migratory potential of candidate compounds to either promote migration for faster wound healing or inhibit migration to prevent vascularization of tumors.

Tube Formation Analysis

Endothelial cells (EC), when provided with a 3D extracellular matrix substrate and appropriately supplemented growth media, will self-organize into a network of capillary-like "tubes." This in-vitro, "tube formation" assay, is commonly used to assess ability of compounds to stimulate or inhibit angiogenesis.
