| 摘要 |
The present invention provides methods and compositions for establishing and maintaining growth of cells and embryonic tissue on a synthetic polymer matrix. For example, the present invention provides synthetic growth matrices for stem cells, gametes, mature differentiated cells, and embryonic tissue (e.g., blastomeres, embryos, and embryoid bodies). In certain embodiments, the cells are capable of going through multiple passages while remaining in an undifferentiated state as a result of the synthetic polymer matrix.
