  • Patent number: 11369718
    Abstract: The present technology relates to a method of augmenting soft facial tissue in a human subject using a liquid suspension including amnion allograft. Analysis of the changes to midface volume, specifically the Ogee curve, observed in the chronological progression of photographs illustrates aesthetic improvements in both Platelet Rich Plasma (PRP) and amnion allograft treatment groups, with changes in the facial grading scale. Less patient downtime and slightly more rapid improvements were noted in the amnion group in comparison to PRP treatment participants. As a result, the amnion allograft provides advantages over the PRP procedure.

  • Patent number: 8936939
    Abstract: The invention provides tissue culture system for primary cells (e.g. normal mammalian primary epithelial progenitors). This system includes: a) a serum-free, chemically defined cell culture media; and, b) methods for isolation and in vitro long-term propagation of primary cells (e.g. primary epithelial cells). Primary cells so isolated and cultured can be kept undifferentiated and proliferate for many weeks (>15 weeks) or population doubling (>35 PD) without senescence, or any detectable genetic alterations. Upon changing media/culture conditions, these cells can be induced to differentiate. The invention also provides methods to transform normal primary cells so cultured into “cancer stem cells.” The genetically defined cancer stem cell tumor model mimics the behavior of the disease closely, e.g., the cells are invasive, hormone responsive and metastatic when injected into mice. The tumor cells express genes that are specific to cancer stem cells identified in patient samples.

  • Patent number: 8835175
    Abstract: A culture medium for human mesenchymal stem cells (hMSC) includes a mesenchymal stem cell basal medium; human leucocyte/platelet coat lysate; insulin; sodium selenite; ethanolamine; and basic fibroblast growth factor. This culture medium is effective for growing hMSC lines, including those which do not grow in culture medium normally used for this type of cell.

  • Patent number: 8835176
    Abstract: The invention relates to the cell disruption of microbes and the preparation of the microbe proteins for mass spectrometric analysis. The cells of microbes from microcolonies are disrupted by physical or chemical means directly on the nutrient medium. The released proteins are then transferred to sample supports by direct contact with their contact surfaces; electrophoresis can be used for assistance. Once the proteins are firmly adsorbed on the contact surfaces, they can be washed with water in order to remove substances which interfere with the ionization process. For analysis by matrix-assisted laser desorption (MALDI), the proteins are prepared on the contact surfaces of the sample supports with matrix substances to form MALDI samples; the sample supports are then introduced into a MALDI mass spectrometer for the acquisition of mass spectra. The microbes are identified by similarity comparisons between the mass spectra of the microbe proteins and similarly obtained reference spectra.

  • Patent number: 8822212
    Abstract: A method for forming at least a tooth root in a tooth containing a tooth crown, including: forming a culture core containing the tooth and a cell-containing base material, the tooth being wrapped with the cell-containing base material, and culturing the culture core in a medium to form at least the tooth root in the tooth contained therein, wherein the cell-containing base material contains at least one kind of cells selected from periodontal ligament-derived cells, bone marrow-derived cells, dental follicle-derived cells, dental pulp-derived cells and dental papilla-derived cells, and the medium contains a component contained in a conditioned medium of a serum-free-cultured cell line of a human uterocervical squamous carcinoma cell line; an additive containing at least one selected from IL-1?, IL-6, IL-8, IL-9, EGF, IGF-I, GH, PDGF-AB, VEGF, LIF, HGF, FGF-2, FGF-1, BMP-2, BMP-4, M-CSF, dexamethasone, insulin, thyroxine, thyrocalcitonin, ascorbic acid and ?-glycerophosphate; or both of them.

  • Patent number: 8815588
    Abstract: We disclose a method of preparing a conditioned cell culture medium, the method comprising the steps of: (a) culturing a mesenchymal stem cell (MSC), a descendent thereof or a cell line derived therefrom in a cell culture medium; and (b) optionally isolating the cell culture medium; in which the mesenchymal stem cell (MSC) is obtained by propagating a cell obtained by dispersing a embryonic stem (ES) cell colony, or a descendent thereof, in the absence of co-culture in a serum free medium comprising FGF2.

  • Patent number: 8815584
    Abstract: The invention provides a method of co-culturing mammalian muscle cells and mammalian motoneurons. The method comprises preparing one or more carriers coated with a covalently bonded monolayer of trimethoxysilylpropyl diethylenetriamine (DETA); suspending isolated fetal mammalian skeletal muscle cells in serum-free medium according to medium composition 1; suspending isolated fetal mammalian spinal motoneurons in serum-free medium according to medium composition 1; plating the suspended muscle cells onto the one or more carriers at a predetermined density and allowing the muscle cells to attach; plating the suspended motoneurons at a predetermined density onto the one or more carriers and allowing the motoneurons to attach; covering the one or more carriers with a mixture of medium composition 1 and medium composition 2; and incubating the carriers covered in the media mixture.
