Table 1. Summary of experimental results obtained with hESC transplantation in mouse embryos.
Experiment | Cell passage | No. of embryos that died | No. of embryos with good integration | No. of embryos with poor integration | No. of embryos with no integration |
---|---|---|---|---|---|
1 | 30 | 0 | 7 | 0 | 2 |
2 | 40 | 1 | 4 | 4 | 0 |
3 | 45 | 4 | 1 | 0 | 3 |
4 | 52 | 0 | 1 | 5 | 0 |
Good integration means six or more EGFP+ cells per 40-μm brain section. Poor integration refers to fewer than six EGFP+ cells per 40-μm brain section.
