DEVICE FOR SEEDING CELLS
A device for seeding cells includes a container with a wall, a bottom and a lid. The wall extends between the bottom and the lid. The container can be equipped to be loaded with cells, in particular with cells form a cell suspension. The container defines a rotation axis. The device is further equipped to rotate the container around the rotation axis. The container includes a structured surface that can be arranged at the inner surface of the container. The structured surface has structures equipped to receive the cells. The rotation exerts a (g-)force in direction of the structured surface, such that the g-force acts perpendicular to the structured surface. The exerted force in the direction of the structured surface resembles a g-force required for sedimentation of the cells into the structures.
ILLUMINATION DEVICE FOR SPATIAL AND TEMPORAL CONTROL OF MORPHOGEN SIGNALING IN CELL CULTURES
Provided are systems and methods for spatially and temporally controlling light with an illumination device comprising a light source operably connected to a circuit board, one or more light guide plates, one or more optical masks, a controller, and a computer readable medium, comprising instructions that, when executed by the controller, cause the controller to: illuminate a cell or a substrate with light from the light source, and spatially and temporally control illumination of light to the cell or the substrate with one or more illumination parameters, wherein the one or more light guide plates provides uniform illumination of the light. Also provided herein are methods of screening using the system and/or device of the present disclosure.
Multi-well micropatterning by ablation
The present invention is drawn to the generation of micropatterns of biomolecules and cells on standard laboratory materials through selective ablation of a physisorbed biomolecule with oxygen plasma. In certain embodiments, oxygen plasma is able to ablate selectively physisorbed layers of biomolecules (e.g., type-I collagen, fibronectin, laminin, and Matrigel) along complex non-linear paths which are difficult or impossible to pattern using alternative methods. In addition, certain embodiments of the present invention relate to the micropatterning of multiple cell types on curved surfaces, multiwell plates, and flat bottom flasks. The invention also features kits for use with the subject methods.
Cellular behaviour monitoring device and method for monitoring changes in cellular behaviour
There is described a cellular behaviour monitoring device for monitoring changes in behaviour of cells contained in a sample. The device generally has a well plate with a sample receiving well recessed therein. A filter membrane extends across the well plate and hermetically covers the sample receiving well. The filter membrane has nutrient-permeable and cell-impermeable pores extending through the filter membrane. The device has an electrode layer extending across the filter membrane. The electrode layer has a substrate and behaviour monitoring electrodes spaced-apart from one another in a region of the substrate, with the region being aligned with the sample receiving well. The electrode layer has nutrient-permeable apertures distributed across the region, with at least some of pores are aligned with at least some of the apertures to allow fluid communication therebetween, and nutrient exchange between the sample receiving well and a surrounding environment.
