Facts: Week 1, size 0.1-0.2 mm Features: adplantation and implantation commences, increase in hCG
This animation shows the process of implantation, occurring during week 2 of development in humans. The beginning of the animation shows: the uterus lining (endometrium epithelium), the hatched blastocyst with a flat outer layer of trophoblast cells (green), the inner cell mass which has formed into the bilaminar embryo (epiblast and hypoblast) and the large fluid-filled space (blastocoel).
