Table 1 Timing of morphological and biochemical changes in the unfertilized Xenopus eggs deposited into different buffers.
From: Unfertilized frog eggs die by apoptosis following meiotic exit
Egg environment | Change in egg morphology | Meiotic exit | Caspase acti- vation | Increase in egg diameter |
|---|---|---|---|---|
Water (j) | within 6 h | within 12 h | 18-36 h | 12-18 h |
DB buffer (d) | within 12 h | within 18 h | 24-36 h | 24-36 h |
OR-2 (j) | within 12 h | within 18 h | 30-48 h | 24-36 h |
OR-2 (d) | within 12 h | within 18 h | 24-36 h | 24-36 h |
