The first chamber comprises a first permeable matrix disposed therein and the first permeable matrix comprises at least one or a plurality of lumens each extending therethrough, which is optionally lined with at least one layer of cells. The second chamber can comprise cells cultured therein. The systems and methods described herein can be used for various applications, including, e.g., growth and/or differentiation of primary cells, and/or simulation of a microenvironment in living tissues and/or organs (to model physiology or disease states, and/or to identify therapeutic agents). The systems and methods can also permit co-cultures of two or more different cell types.

    摘要: A microfluidic device for determining a response of cells comprises a microchannel and a seeding channel. The microchannel is at least partially defined by a porous membrane having cells adhered thereto. The microchannel has a first cross-sectional area. The seeding channel delivers a working fluid to the cells within the microchannel. The seeding channel has a second cross-sectional area that is less than the first cross-sectional area such that a flow of the working fluid produces a substantially higher shear force within the seeding channel to inhibit the attachment of cells within the seeding channel. And when multiple seeding channels are used to deliver fluids to multiple microchannels that define an active cellular layer across the membrane, the seeding channels are spatially offset from each other such that fluid communication between the fluids occurs only at the active region via the membrane, not at the seeding channels.

    摘要: A cell culturing platform for modeling myelination in vitro comprises first cell chambers (102a, 102b) for containing somas of neuronal cells, a process chamber (103) connected to the first cell chambers with first channels, and a second cell chamber (105) for containing somas of the myelinating cells and connected with second channels to the process chamber. The first channels allow processes of the neuronal cells to enter the process chamber and inhibit the somas of the neuronal cells from moving from the first cell chambers to the process chamber. The second channels allow processes of the myelinating cells to enter the process chamber and inhibit the somas of the myelinating cells from moving from the second cell chamber to the process chamber. Hence, the process chamber, where the myelination takes place, is substantially free from the cell somas and thus detection of the myelination is facilitated.
