  • Patent number: 10544388
    Abstract: Compositions and methods are provided for modulating the growth, development and repair of bone, cartilage or other connective tissue. Devices and stimulus waveforms are provided to differentially modulate the behavior of osteoblasts, chondrocytes and other connective tissue cells to promote proliferation, differentiation, matrix formation or mineralization for in vitro or in vivo applications. Continuous-mode and pulse-burst-mode stimulation of cells with charge-balanced signals may be used. Bone, cartilage and other connective tissue growth is stimulated in part by nitric oxide release through electrical stimulation and may be modulated through co-administration of NO donors and NO synthase inhibitors. Bone, cartilage and other connective tissue growth is stimulated in part by release of BMP-2 and BMP-7 in response to electrical stimulation to promote differentiation of cells.

  • Patent number: 8809044
    Abstract: This invention relates to methods and devices that improve cell culture efficiency. They include the use of gas permeable culture compartments that reduce the use of space while maintaining uniform culture conditions, and are more suitable for automated liquid handling. They include the integration of gas permeable materials into the traditional multiple shelf format to resolve the problem of non-uniform culture conditions. They include culture devices that use surfaces comprised of gas permeable, plasma charged silicone and can integrate traditional attachment surfaces, such as those comprised of traditional tissue culture treated polystyrene. They include culture devices that integrate gas permeable, liquid permeable membranes. A variety of benefits accrue, including more optimal culture conditions during scale up and more efficient use of inventory space, incubator space, and disposal space. Furthermore, labor and contamination risk are reduced.

    Abstract: A biologically implantable containment device having a wet seal, the device being adaptable for drug formulations or cell suspensions. A porous membrane, in a tubular configuration, is formed and can be configured as part of a closed cell-tight system for loading. During loading, the containment device membrane is wet, while the loading system remains cell-tight. The containment device is wet-sealed through a combination of heat and pressure, while the system remains cell-tight. Sealing the containment device substantially or completely eliminates metabolic functioning of any organisms in the vicinity of the closure. The wet-seal is formed by melting a thermoplastic material that is in contact with the membrane. The containment device is separated from the cell-tight loading system, which remains closed after separation.
