Stem Cell Related Patent Number US6875608
| Title: | Propagation and/or derivation of embryonic stem cells | | Inventors: | Smith, Austin Gerard; Edinburgh, United Kingdom
Burdon, Thomas Grant; Edinburgh, United Kingdom | | Summary: | Described herein are methods of culturing embryonic stem (ES) cells without differentiation, and uses thereof. The invention relates to ES cells that are cultured in the presence of a compound which selectively inhibits the propagation or survival of cells other than ES cells. The ES cells are described as not having been genetically altered, but rather, the compound employed herein inhibits a signaling pathway which is essential for the propagation of differentiated cells but not for the propagation of ES cells. The resulting ES cells are selectively maintainable in the culture, and are useful for studying the regulation of stem cell self-renewal, in media that are selective against differentiated cell types. | | Abstract: | Embryonic stem (ES) cells are cultured in the presence of a compound which selectively inhibits propagation or survival of cells other than ES cells.
