| Day | Event |
|---|---|
| 9 | Ovulation beginning contact. Endometrial proliferation to form epithelial plaque. |
| 10 | Invasion. Erosion of strorna, gland and vessels. Lacunae beginning. Transition of cytotrophoblast to syncytium. |
| 12 | Trabeculae and cascades of trophoblast cells. Mesoblast, yolk sac. Ovum walls collapsed, no sinusoids. |
| 13 | Sinusoids communicate with lacunae. Villi begin. Ovum walls dilated, abembryonic wall hypertrophies preparatory to formation of second implantation site. |
| 15 | Maternal epithelium reaches end of proliferative period. |
| 17 | Necrotic border zone. Blood in glands. Primitive body mesoderm. |
| 19 | Villi with three zones established, and branching. Pinocytosis (imbibing of liquid substances}. |
| 22.5 | Villi vascular. Oedema at junction zone. |
