Abstract: Choroid plexus epithelial cells are generated in a culture medium using embryonic stem cells and adding an effective amount of bone morphogenetic protein and/or other members of the transforming growth factor beta (TGF-beta) superfamily. Generation of such choroid plexus epithelial cells are confirmed using a combination of genetic markers, antibodies, histology inspection, functional assays, and integration into the endogenous choroid plexus in mice.

Abstract: A microfluidic separation device includes a microchannel formed in a substrate and being defined at least by a bottom surface, a first side wall, and second side wall. Fluid containing particles or cells is flowed through the microchannel from an upstream end to a downstream end. The downstream end terminates in a plurality of branch channels. A plurality of vertically-oriented electrodes are disposed on the first wall and on the second wall opposite to the first wall. A voltage source is connected to the plurality of opposing electrodes to drive the electrodes. The opposing, vertically-oriented electrodes may be used to focus a heterogeneous population of particles or cells for subsequent downstream separation via additional electrodes placed on one of the side walls. Alternatively, the opposing, vertically-oriented electrodes may be used to spatially separate a heterogeneous population of particles or cells for later collection in one or more of the branch channels.
