  • Publication number: 20130224856
    Abstract: The present invention relates to a large-scale propagation and maintenance method of embryoid bodies generated from stem cells. More particularly, the present invention relates to a large-scale propagation and maintenance method of embryoid bodies retaining their intrinsic characteristics for a long period of time, comprising the step of continuously subculturing embryoid bodies that are primarily produced from embryonic stem cells or from induced pluripotent stem cells. According to the method of the present invention, after preparation of embryoid bodies from a limited number of stem cells, large-scale production and maintenance of embryoid bodies can be realized by a simple mechanical subculturing method without the continuous supply of stem cells.

  • Publication number: 20120322045
    Abstract: Methods of isolating cellular products, such as pancreatic islets, may be used in diabetes research and therapeutic transplantation. The methods may involve providing a tissue having desired cells that are less prone to destructive freezing and undesired cells that are more prone to destructive freezing, or pre-treating a tissue to have such characteristics. The methods may involve freezing the tissue, disrupting the tissue, warming the tissue, and separating the desired cells from undesired cellular material to obtain the cellular product. The methods may thereby provide an enzyme-free or reduced-enzyme method of isolating a cellular product that is more consistent, reliable and less toxic than conventional methods. The methods may also yield an optimum quantity of cellular product that retain sufficient functional integrity to be useful as a transplantation resource.

    Abstract: The invention is directed to novel cells that are derived from human embryoid bodies. Such embryoid body-derived (EBD) cells are relatively uncommitted or progenitor (e.g., pluripotent) cells. EBD cells, while not immortal, display long-term proliferation in culture with a normal karyotype and can be cryopreserved and cloned. They can be efficiently transfected with retroviruses and lentivirus and genetically manipulated. Although they have a developmentally broad multilineage expression profile, they do not form tumors when injected into severe combined immunodeficiency (SCID) mice. As a result, EBD cells have a variety of uses, for example, in transplantation therapies.

  • Publication number: 20100190252
    Abstract: The invention relates to a process for generating fibroblasts, more particularly, to the culturing of fibroblasts in large numbers and of the heterogenic type. The invention is also directed to the use of fibroblasts in the preparation of heterotypic spheroids and a process for the preparation of such heterotypic spheroids.

  • Publication number: 20100159564
    Abstract: The identification of the most sensitive sites of Clostridium histolyticum collagenase Class 1 to proteolysis by proteases present during the fermentation and purification of the enzyme is described. Culture supernatant obtained after fermentation of C. histolyticum is used as the starting material for further purification of the enzyme. Native collagenase Class 1 and its proteolytic fragments are partially purified by a combination of hydrophobic interaction and strong anion exchange chromatographies. The pools containing enriched levels of the proteolytic fragments are further purified by high performance anion exchange chromatography. These polypeptides are then characterized by Q-TOF mass spectroscopy. A total of three sensitive bonds are identified along with substitution and deletion strategies that will result in resistance of the enzyme to proteolytic degradation.

  • Publication number: 20100144032
    Abstract: The present invention provides a process for isolating vascular endothelial cells from embryoid bodies differentiated from embryonic stem cells, which comprises: (a) treating embryoid bodies differentiated from embryonic stem cells with 0.005-0.015% trypsin and 0.05-0.15 mM ethylenediaminetetraacetate (EDTA) to obtain vascular endothelial cell clusters; and (b) treating the vascular endothelial cell clusters with 0.1-0.5% trypsin and 0.5-2 mM EDTA so as to separate the vascular endothelial cell clusters into single cells.

  • Patent number: 7723108
    Abstract: The present invention is a process for preparing soft tissue such as tendons, ligaments, cartilage, fascia, dermis, human valves and human veins for implant in a human and removes cellular components and forms an decellular matrix having as major components collagens and elastins while sterilizing the tissue. The process comprises the following steps: (1) isolating from a suitable donor a desired soft tissue sample of the biological material; (2) processing and decellularizing the soft tissue including inspection for visual defects, trimming and soaking the tissue in a detergent depending on whether the tissue is fascia or dermis and rinsing same with sterile water; (3) sterilizing the soft tissue in a vacuum and soaking the tissue in an antibiotic composition or peracetic acid depending on whether the soft tissue is fascia or dermis and rinsing same; (4) processing the tissue by cutting the tissue to size and perforating the tissue; and (5) dipping the tissue in 70% ethanol and packaging the tissue.
