Table III. Post-implantation development of single (1X) and aggregate (2X) clone blastocysts.
| Clone aggregate | Blastocysts transferred (n) | Pregnant uterine horns (n) | Decidua (n) (% of blastocysts) | 10.5 d.p.c. (n) (% of blastocysts) | Full-term (n) (% of blastocysts) |
|---|---|---|---|---|---|
| clone 1X | 109 | 14/16 | 62 (57)a | 2 (3.0)a | n.a. |
| clone 2X | 201 | 16/16 | 131 (65)a | 16 (12.0)b | n.a. |
| clone 1X | 391 | 11/23* | n.a. | n.a. | 4 (1.0)a |
| clone 2X | 98 | 5/7* | n.a. | n.a. | 8 (8.2)b |
n.a., not applicable; d.p.c., days post coitum. *The uterine horns were of separate recipients.
Replicates in each embryo group: 14 for midgestation analysis, >4 for full-term analysis. Values within the same column not sharing a common superscript letter are significantly different (P < 0.05).
