| 21. | Filled with uterine fluid, the blastocyst breaks out of the zona pellucida and undergoes implantation.
|
| 22. | Once the sperm cells find their way past the zona pellucida, the cortical reaction occurs.
|
| 23. | In 24 to 48 hours, the zona pellucida breaches.
|
| 24. | N-acetylglucosamines on the zona pellucida normally promote sperm binding.
|
| 25. | In mammals, however, the extracellular matrix modified by the cortical reaction is the zona pellucida.
|
| 26. | ZP3 is the receptor in the zona pellucida which binds sperm at the beginning of fertilization.
|
| 27. | ZP3, a glycoprotein in the zona pellucida, is responsible for egg / sperm adhesion in mice.
|
| 28. | During the freezing process, the zona pellucida, or shell of the egg can be modified preventing fertilization.
|
| 29. | The zona pellucida ( ZP ) is a specialized extracellular matrix that surrounds the oocyte and early embryo.
|
| 30. | Porcine zona pellucida has its critics.
