    摘要: A novel growth method is provided for pluripotent stem cells such as ES cells. The method of the invention is a pluripotent stem cell growing method and gene transfer method in which pluripotent stem cells are cultured under conditions that maintain their undifferentiated state and pluripotency, the method being characterized by using a liquid medium and a culturing vessel having immobilized or coated on a substrate solid phase surface a molecule which is adhesive to the pluripotent stem cells in a fixed concentration, to grow the pluripotent stem cells in a dispersed state while maintaining their undifferentiated state and pluripotency, without using feeder cells, or to transfer and express a gene therein.

    摘要: This relates to a contrast medium containing a complex of a gadolinium (Gd) type contrast agent and a polymer. More particularly, the contrast medium wherein the polymer capable of phase transit in response to environmental changes, particularly, pH, light or temperature, to develop a different water solubility, and a method for imaging by the use of this contrast medium. By binding a polymer responsive to microenvironmental changes with a Gd type MRI contrast agent, on-off switching of MRI imaging capability is enabled, wherein imaging occurs only on the target sites. Consequently, a highly specific MRI contrast medium can be obtained, whereby a highly specific MRI diagnosis is made possible, wherein only the target sites such as a tumor and a particular site are imaged and otherwise at the site where imaging is not necessary.
