  • Publication number: 20140113371
    Abstract: A method of preserving haptenized tumor cells is described. The method employs a freezing medium containing an effective amount of sucrose and human serum albumin in an isotonic buffered saline solution. Cryogenically preserving haptenized cells in such a medium has been found to maintain the integrity of the tumor cells during storage. The haptenized tumor cells also retain cell-associated antigens and haptens, and are as immunogenic, i.e., capable of inducing immunotherapeutic response, as fresh vaccine in a mouse model of metastatic disease. In a specific embodiment, haptenized cells are exposed to a solution of 8% sucrose, 10% human serum albumin in Hank's buffered solution, and then frozen to ?80° C. overnight and then stored in a liquid nitrogen freezer. Methods of storing haptenized tumor cells and compositions are also provided.

    Abstract: Disclosed are compositions and methods for increasing the longevity of a cell culture and permitting the increased production of proteins, preferably recombinant proteins, such as antibodies, peptides, enzymes, growth factors, interleukins, interferons, hormones, and vaccines. Cells transfected with an apoptosis-inhibiting gene or vector, such as a triple mutant Bcl-2 gene, can survive longer in culture, resulting in extension of the state and yield of protein biosynthesis. Such transfected cells exhibit maximal cell densities that equal or exceed the maximal density achieved by the parent cell lines. Transfected cells can also be pre-adapted for growth in serum-free medium, greatly decreasing the time required to obtain protein production in serum-free medium. In certain methods, the pre-adapted cells can be used for protein production following transformation under serum-free conditions. The method preferably involves eukaryotic cells, more preferably mammalian cells.

    Abstract: The invention discloses a multi-layer cell freezing vial and method of ohtention thereof. The method of obtention is a cell freezing and thawing process that avoids the need of incorporating new fresh medium to the thawed cells for the dilution of the cryoprotective agent. This is achieved by the previous freezing of an extra layer of culture medium in addition to the frozen ceil solution containing said cryoprotective agent. At the time of thawing, the culture medium and the cell solution mix themselves, turning the concentration of said cryoprotective agent to a non-toxic dilution and achieving the effective exclusion of said cryoprotective agent from the living cells.

  • Publication number: 20130273654
    Abstract: The present invention it was determined that dendritic cells could be derived from various sources including peripheral blood monocytes in the presence of only GM-CSF without other cytokines if the monocytes were not activated. By preventing activation, such as by preventing binding of the cells to the surface of the culture vessel, the monocytes do not require the presence of additional cytokines, such as IL-4 or IL-13, to prevent differentiation into a non-dendritic cell lineage. The immature DCs generated and maintained in this manner were CD14? and expressed high levels of CD1a. Upon maturation by contact with an agent such as, for example, BCG and IFN?, the cells were determined to express surface molecules typical of mature dendritic cells purified by prior methods and cultured in the presence of GM-CSF and IL-4.

  • Publication number: 20130236960
    Abstract: The vitrification medium for cells according to the present invention is a vitrification medium for cells comprising a cell membrane permeable substance and a cell membrane non-permeable substance, in which, the content of the cell membrane permeable substance is in the range of 30 to 50% by volume, and the osmotic pressure generated in association with the cell membrane non-permeable substance, which is a fraction of the total osmotic pressure on the cell membrane on suspending the cells in the vitrification medium, is in the range of 280 mOsm or more. The vitrification medium for cells according to the present invention is excellent in operability and safety.

  • Patent number: 8529883
    Abstract: Dosage units consist of an autologous cell therapy product composed of fibroblasts grown for each individual to be treated. The suspension of autologous fibroblasts, grown from a biopsy of each individual's own skin using current good manufacturing practices (CGMP), and standard tissue culture procedures, is supplied in vials containing cryopreserved fibroblasts or precursors thereof, having a purity of at least 98% fibroblasts and a viability of at least 85%, for administration of from one to six mL, preferably two mL, of cells at a concentration of from 1.0-2.0×107 cells/mL. When injected into the nasolabial fold wrinkles (creases on the sides of the nose that extend to the corners of the mouth), the autologous fibroblasts are thought to increase the synthesis of extracellular matrix components, including collagen, reducing the severity of these wrinkles. Dosage and timing of administration have been demonstrated to be critical to achieving clinically significant outcomes.

  • Patent number: 8524493
    Abstract: The present invention is directed to methods of detecting viable epithelial cells in a sample. The method includes isolating the sample comprising cells from a patient and culturing the cells for a time sufficient for an epithelial cell-specific marker to be released from the cells. The marker includes a substantially full-length cytokeratin. The method further includes detecting the released marker. Detection of the marker indicates the presence of disseminated epithelial cells. Methods are also directed to identifying disseminated epithelial tumor cells.

  • Publication number: 20130217123
    Abstract: The present invention relates to a method for cryopreserving the pulp of a non-exfoliated deciduous tooth, comprising a step of making with a laser a hole into the tooth removed from its physiological seat on the tooth neck. After making the hole, the tooth is contacted with a cryopreserving agent and then cryofrozen. An object of the invention further consists in mesenchymal stem cells isolated from the pulp of a cryopreserved tooth according to the method of the invention.

    Abstract: Disclosed is an implantable material comprising a biocompatible matrix and cells which, when provided to a vascular access structure, can promote functionality generally. For example, implantable material of the present invention can enhance maturation of an arteriovenous native fistula as well as prolong the fistula in a mature, functional state suitable for dialysis. Additionally, the present invention can promote formation of a functional arteriovenous graft suitable for dialysis as well as promote formation of a functional peripheral bypass graft. Implantable material can be configured as a flexible planar form or a flowable composition with shape-retaining properties suitable for implantation at, adjacent or in the vicinity of an anastomoses or arteriovenous graft. According to the methods disclosed herein, the implantable material is provided to an exterior surface of a blood vessel. Certain embodiments of the flexible planar form define a slot.
