  • Patent number: 8148152
    Abstract: Provided are means and methods for producing embryoid bodies (EBs) from multi- or pluripotent cells. In particular, a method of generating embryoid bodies (EBs) is described comprising agitation of a liquid suspension culture of multi- or pluripotent cells in a container until generation of cell aggregates, optionally diluting the suspension, and further agitation of the suspension until formation of EBs. Furthermore, the present invention relates to the use of the novel culturing method and EBs obtained thereby for a variety of applications including genomics, diagnostic assays, teratogenic/embryotoxicological and pharmacological assays as well as for the provision of tissue grafts.
    Type: Grant

    Assignee: Axiogenesis AG
    Inventors: Eugen Kolossov, Ralf Kettenhofen, Isabella Kopp, Heribert Bohlen, Silke Schwengberg
  • Publication number: 20110059456
    Abstract: The invention relates to a system for selecting differentiating embryonic or adult stem cells or embryonic germline cells in a cell-specific and development-specific manner, using a combination of resistance genes and detectable reporter genes under the common control of a cell-specific and/or development-specific promoter.
