  • Publication number: 20210324313
    Abstract: An apparatus for collecting or culturing cells or cell colonies includes: a common substrate formed from a flexible resilient polymeric material and having a plurality of wells formed therein; and a plurality of rigid cell carriers releasably connected to said common substrate, with said carriers arranged in the form of an array, and with each of the carriers resiliently received in one of the wells. A method of collecting or culturing cells or cell colonies with such an apparatus is carried out by depositing a liquid media carrying cells on the apparatus so that said cells settle on or adhere to said the carriers; and then (c) releasing at least one selected carrier having said cells thereon by gradual application of release energy to each carrier from the cavity in which it is received (e.g., by pushing with a probe).

  • Publication number: 20210087515
    Abstract: Disclosed herein are devices, apparatuses and methods for generating self-sustaining gaseous and non-gaseous gradients across a cell support structure and for culturing one or more cells or tissues under hypoxic conditions. Methods of generating one or more gas gradients across a cell support structure include providing a luminal container having a bottom wall that is a gas permeable membrane, positioning a cell support structure above the bottom wall, positioning one or more cells or tissues on the cell support structure, and generating one or more gas gradients between the bottom wall, across the cell support structure and into a luminal reservoir. An apparatus to produce hypoxic conditions for cell cultures includes a luminal container having a bottom wall, a cell support structure on the bottom wall, and a cover that sealably closes the open top, such that a hypoxic condition can be generated in the luminal reservoir.

  • Publication number: 20180217494
    Abstract: A method for pattern transfer to a silicone-based microstructure device comprises the steps of molding a silicone-based negative replica from a lithography patterned master mold. An epoxy resin-based master mold is molded from the silicone-based replica. A surface of the epoxy resin-based master mold is coated with a layer of Cr and then with a layer of Au on the CR layer to facilitate demolding of a silicone-based material. The silicone-based microstructure device is then molded from the coated epoxy resin-based master mold, wherein the silicone-based microstructure device has a dimensional pattern that substantially corresponds to the dimensional pattern of the lithography patterned master mold.
