| 摘要 |
The invention provides novel gangliosides and mixtures of novel gangliosides and drug products containing the same. The invention also provides cells induced to over-express one or more gangliosides. The invention further provides methods for production of gangliosides, e.g., GM1, from cells in culture using, for example, bone marrow cells and neuroblastoma cells. Methods include the treatment of cells with neural induction media and chloroquine, or chloroquine alone in the case of e.g., human bone marrow cells, neuraminidase or glucosamine, to induce the production of gangliosides, e.g., GM1, in the cells. Also provided are methods of long-term, high density culturing of cells without passaging to produce gangliosides, e.g., GM1. Methods of quantifying gangliosides, e.g., GM1 in cell culture are also provided. |
