  • Patent number: 10913925
    Abstract: The systems and methods disclosed herein are generally related to a cell culture system. More particularly, the systems and methods enable the culturing and interconnecting of a plurality of tissue types in a biomimetic environment. By culturing organ specific tissue types within a biomimetic environment and interconnecting each of the organ systems in a physiologically meaningful way, experiments can be conducted on in vitro cells that substantially mimic the responses of in vivo cell populations. In some implementations, the system is used to monitor how organ systems respond to agents such as toxins or medications. The system enables the precise and controlled delivery of these agents, which, in some implementations, enables the biomimetic dosing of drugs in humans to be mimicked.

  • Publication number: 20200292944
    Abstract: Customizable hydrogel patterned into arrays of microwells, microchannels, or other microfeatures, and a process to prepare patterned hydrogel adherent to a solid support, are provided. A pattern of light is applied to photopolymerizable hydrogel precursor solution on a solid support, resulting in the formation of a patterned hydrogel bonded to the solid support. Hydrogel precursor solution is held by a ring of a customized height secured to a photomask or to a surface allowing transmission of a pattern of light. This process allows for facile customization and repeated fabrications of hydrogel microwells of desired heights and geometries with a micron or submicron scale resolution, adherent on various solid supports.

  • Publication number: 20050260179
    Abstract: A method for capturing stem cells and/or progenitor cells from circulating body fluids such as blood or lymph in vivo and enabling the cells to colonize a specific, localized site for purposes of tissue regeneration or repair, has been developed. The method consists of selecting a site in need of repair or regeneration. Materials which can be used to provide the growth factors or ligands include polymeric matrices having the growth factor or ligands attached thereto, materials releasing growth factor or ligands (such as hydrogels, polymers, fibrin clots), and cells which release or have bound to their surfaces the growth factors or ligands.

  • Publication number: 20050260745
    Abstract: A system has been constructed that recapitulate the features of a capillary bed through normal human tissue. The system facilitates perfusion of three-dimensional (3D) cell monocultures and heterotypic cell co-cultures at the length scale of the capillary bed. A major feature is that the system can be utilized within a “multiwell plate” format amenable to high-throughput assays compatible with the type of robotics commonly used in pharmaceutical development. The system provides a means to conduct assays for toxicology and metabolism and as a model for human diseases such as hepatic diseases, including hepatitis, exposure-related pathologies, and cancer. Cancer applications include primary liver cancer as well as metastases. The system can also be used as a means of testing gene therapy approaches for treating disease and inborn genetic defects.

  • Patent number: 6730298
    Abstract: Slowly polymerizing polysaccharide hydrogels have been demonstrated to be useful as a means of delivering large numbers of isolated cells via injection. The gels promote engraftment and provide three dimensional templates for new cell growth. The resulting tissue is similar in composition and histology to naturally occurring tissue. This method can be used for a variety of reconstructive procedures, including custom molding of cell implants to reconstruct three dimensional tissue defects, as well as implantation of tissues generally.

  • Patent number: 5709854
    Abstract: A cell-polymeric solution is injected into an animal where the polymer crosslinks to form a polymeric hydrogel containing dispersed cells and the cells form new tissue in the animal. The polymer is biodegradable and is a natural polymer such as alginate or a synthetic polymer. The cells are chondrocytes, osteoblasts, muscle cells, fibroblasts or cells acting primarily to synthesize, secret or metabolize materials. Crosslinking of the polymer results from using cations or anions, altering the pH or changing the temperature. A polyion such as polyethyleneimine or polylysine can be added before injection to stabilize the polymeric hydrogel. A kit for tissue formation is provided by combining the cell-polymeric solution with a means for injecting the solution into an animal.
