WebMay 9, 2024 · When two egg cells are fertilized independently by two sperm cells, two zygotes are produced. These two separate zygotes develop into two separate embryos which result in two different offspring. They are known as fraternal twins or non-identical twins. They are also referred to as dizygotic twins since they are derived from two … WebThe zygotes were cultured at 38.5°C, 5% CO 2 in air and high humidity. The number of two-, four- and eight-cell embryos were recorded at 32, 42 and 72 h, respectively, and blastocyst yield was assessed at Day 7. 2.7 Measurement of intracellular ROS levels
WebResults showed that vitrification of pronuclear zygotes did not affect the global transcriptional activity of 2-cell embryos (Figure 4A,B). However, compared to the control group, vitrification significantly reduced the global transcriptional activity of 4-cell and 8-cell embryos ( Figure 4 C–F).
