摘要:
The present invention provides a method for forcingly culturing a piece of human periosteum tissue in a shorter culture period, the method including the steps of: (1) placing a periosteum piece dissected from a patient on a culture dish containing no culture solution; (2) dropping platelet-rich plasma collected from the patient onto the surface of the periosteum piece on the culture dish and coagulating the platelet-rich plasma so as to cover the surface of the periosteum piece; (3) adding a first culture medium to the culture dish and growing the culture; and (4) growing the culture in a second culture medium containing a basic fibroblast growth factor and no platelet-rich plasma, after the step (3).
摘要:
Methods for obtaining osteoprogenitors, osteoblasts or osteoblast phenotype cells, as well as cell populations including such cells, from human bone marrow stem cells in vitro or ex vivo are disclosed. Bone marrow stem cells are contacted with human serum or plasma and a growth factor or a biologically active variant or derivative thereof. In addition, osteoprogenitor, osteoblast or osteoblast phenotype cell types and cell populations are provided. The cell populations may include additional cell types, such as endothelial cells or progenitors. The osteoprogenitors, osteoblasts or osteoblast phenotype cells may be used in therapy, particularly bone therapy.
摘要:
The present invention relates to a method for growing, rapidly and massively ex vivo, cells collected from a living subject to provide a safe and effective pharmaceutical preparation for biological tissue repair/regeneration. Specifically, the present invention relates to a method for growing cells in a sample collected from a living subject by culturing the cells in a medium containing allogeneic (including autogenic) serum. Preferably the allogeneic serum has been determined as being negative for a serum tumor marker and/or an infectious factors, and the amount of the anticoagulant (e.g., heparin, a heparin derivative, or a salt thereof) added to the collected sample is less than 5 U/mL with respect to the volume of the sample or the amount of the anticoagulant in the medium at the start of culture is less than 0.5 U/mL. The present invention further relates to use of the method.
摘要:
PROBLEM TO BE SOLVED: To provide a mammalian cell medium obtained by substituting an animal-originated serum with a human plasma fraction. SOLUTION: There is provided the medium for culture of mammalian cell, containing a supernatant derived from a stage of a human plasma fraction obtained by Cohn process in addition to ordinary nutrients of a basal medium.
