In vitro development of monkey sperm-fertilized embryos and parthenotes and ESC isolation efficiency
| Embryo origin | n | Cleaved (%) |
Eight-cell (%) | Morula (%) |
Blastocyst (%) | Blastocysts used for ESC isolation |
PESC lines isolated (%) |
|---|---|---|---|---|---|---|---|
| Conventional IVF | 71 | 50 (70) | 47 (94) | 38 (76) | 27 (54)a | 0 | NA |
| Intracytoplasmic sperm injection | 40 | 38 (95) | 32 (84) | 29 (76) | 19 (50)a | 0 | NA |
| Parthenotes | 104 | 100 (96) | 96 (96) | 93 (93) | 38 (38)a | 17 | 5 (29) |
Percentages of eight-cell, morulae, compact morulae, and blastocysts are calculated based on the number of cleaved embryos.
