    摘要: The sustaining stem cells for example, hematopoietic stem cells while holding in the undifferentiated state and maintaining pluripotency by providing a polypeptide having a WIF domain for example, WIF-1 to the stem cells has been successfully achieved. This polypeptide preferably also contains an EGF-like repeat. This result has been achieved by providing a polypeptide preferably having the WIF domain together with a stem cell survival factor such as SCF. Thus, it becomes possible to easily provide a large amount of stem cells for example, hematopoietic stem cells containing functional precursor cells. It has also become possible to more efficiently transfer a gene into the stem cells. Because it is homogeneous and almost free from impurities, the stem cell composition can remarkably relieve side effects for example, infection, which occur in conventional therapies using hematopoietic stem cells.

    摘要: The cell observation using a conventional well plate takes much costs. Each well 3 being opened at a top plate 2a of the well plate 1 has a diameter reduced portion 32 which inner circumferential surface 32a is conically hollowed. At a lower portion of the diameter reduced portion 32 is formed an inserting hole 33. In a detecting portion 4, an outer circumferential surface of a round-bar reference electrode 41 is covered by an insulating portion 42. The detecting portion 4 has an upper end portion 4a and a lower end portion 4b which outer circumferential surface is exposed to an outside without being covered by an insulating portion 42. On an upper side above the lower end portion 4b is formed a diameter expanded portion 4c in which an outer circumferential surface of the insulating portion 42 is covered with a measuring electrode 43. The detecting portion 4 is fixed to a well 3 whose diameter expanded portion 4c is inserted into an inserting hole 33 and its upper end portion 4a is contained in the well 3. In the detecting portion 4, the upper end surface 43a of the measuring electrode 43 is communicated with an inner circumferential surface 32a of the diameter reduced portion 32 positioned in an edge surrounding portion of the inserting hole 33.

    摘要: The present invention relates to a method and substance for maintaining the pluripotency and self-replication ability of a stem cell, such as a hematopoietic stem cell, while keeping it undifferentiated. Specifically, the present invention provides a composition for maintaining the expansion or pluripotency of a stem cell, comprising active STAT5, and a method using the same. STAT5 may be in the form of a protein or a nucleic acid. The composition may contain a cellular physiologically active substance (e.g., SCF, TPO, Flt-3L, etc.). The present invention also relates to a cell, a tissue and an organ prepared from the stem cell.

    摘要: It is intended to provide a regenerable cell in which a desired chromosome has been deleted, a method for producing the cell, and a gene cassette and a kit to be used for the method. More particularly, it is intended to obtain an individual corresponding pluripotent stem cell easily and simply. More specifically, it is intended to efficiently establish a cell, tissue or organ that can be a donor for treating a disease without causing immune rejection response, without newly obtaining and establishing a stem cell such as ES cell from the individual, and without using an ovum as a material. It was achieved by a gene cassette in which not two recombinase recognition sites in a cis orientation are inserted, but one recombinase recognition site or two recombinase recognition sites in an opposite orientation is/are inserted and a marker gene is connected, and by application of the gene cassette to a cell fusion technique.
