  • Publication number: 20180044623
    Abstract: The presently disclosed subject matter provides a microfluidic device that can simulate capillary blood flow on a fetal side of the device and pooled blood on a maternal side of the device (i.e., intervillous space). The microfluidic device can reconstitute the maternal-fetal interface, can expand the capabilities of cell culture models, and can provide an alternative to current maternal-fetal transfer models.

  • Publication number: 20180023050
    Abstract: Compositions, devices and methods are described for improving adhesion, attachment, and/or differentiation of cells in a microfluidic device or chip. In one embodiment, one or more ECM proteins are covalently coupled to the surface of a microchannel of a microfluidic device. The microfluidic devices can be stored or used immediately for culture and/or support of living cells such as mammalian cells, and/or for simulating a function of a tissue, e.g., a liver tissue, muscle tissue, etc. Extended adhesion and viability with sustained function over time is observed.

  • Publication number: 20170349871
    Abstract: System and method includes a body having a central microchannel separated by one or more porous membranes. The membranes are configured to divide the central microchannel into a two or more parallel central microchannels, wherein one or more first fluids are applied through the first central microchannel and one or more second fluids are applied through the second or more central microchannels. The surfaces of each porous membrane can be coated with cell adhesive molecules to support the attachment of cells and promote their organization into tissues on the upper and lower surface of the membrane. The pores may be large enough to only permit exchange of gases and small chemicals, or to permit migration and transchannel passage of large proteins and whole living cells. Fluid pressure, flow and channel geometry also may be varied to apply a desired mechanical force to one or both tissue layers.
