  • Patent number: 9845459
    Abstract: The present invention relates to a method of obtaining high purity stem cells from tissue, comprising: providing an impurity-containing cell mass obtained from a tissue; providing a filter device which comprises a cylinder structure, wherein the cylinder structure comprise an inlet and an outlet below and a content configured inside the cylinder structure between the inlet and the outlet; culturing the impurity-free cell mass on a polymeric film, wherein target stem cells of the impurity-free cell mass conjugate into a spheroid cell population; collecting the spheroid cell population from the polymeric film to obtain high purity target stem cells. According to the method of the present invention, stem cells can be rapidly and easily obtained from tissue. Only a small amount of tissue sample is required and the stem cells obtained can be readily used in clinical applications such as autotransplantation without the requirement of in vitro amplification.

  • Patent number: 8097274
    Abstract: Provided herein are skin substitutes suitable for use in a living subject for purpose of repairing damaged tissues, methods of producing the skin substitutes and their uses. A biocomposite membrane comprising poly(?-caprolactone) (PCL) and at least one material selected from collagen and gelatin is provided. In one embodiment, the biocomposite is a 2-component membrane of PCL and gelatin. In another embodiment, the biocomposite is a 3-component membrane of PCL, collagen and gelatin. The bio-composite membrane may be used directly in vivo as a wound dressing, or as a support for cell growth on each side of the membrane to produce an in vitro cultivated artificial skin for future in vivo and/or in vitro applications.
