  • Publication number: 20210370298
    Abstract: Methods for separating cells from a sample (e.g., separating fetal red blood cells from maternal blood) include introducing a sample including cells into one or more microfluidic channels. In one embodiment, the device includes at least two processing steps. For example, a mixture of cells is introduced into a microfluidic channel that selectively allows the passage of a desired type of cell, and the population of cells enriched in the desired type is then introduced into a second microfluidic channel that allows the passage of the desired cell to produce a population of cells further enriched in the desired type. The selection of cells is based on a property of the cells in the mixture, for example, size, shape, deformability, surface characteristics (e.g., cell surface receptors or antigens and membrane permeability), or intracellular properties (e.g., expression of a particular enzyme).

  • Publication number: 20140370593
    Abstract: A flow chamber assembly for subjecting cells or other biological reagents to laminar flow conditions and methods of using the flow chamber assembly are provided herein. The flow chamber assembly includes a bottom plate having at least one well with a bottom surface adapted to receive the cells or biological reagents, a top plate having at least one flow protrusion positioned and shaped to fit into the well of the bottom plate and a sealing element positioned between the top plate and the bottom plate when the top plate and the bottom plate are attached. The flow chamber assembly is configured to allow for laminar flow of a perfusate across the cells or biological reagents along the bottom surface of the well of the bottom plate. The cells or biological reagents can be exposed to a predetermined level of shear stress.
