There was one "hyaline sphere" in the blastocoele. The larvae began gastrulation, but further development then stopped, and the animals died [52].

Blastocoele formation and cell allocation to the inner cell mass and trophectoderm in haploid and diploid pig parthenotes developing in vitro.
After three days of culture, the embryos were checked for blastocoele development.
Within 5 to 12 days, the embryo becomes a blastocyst (Figure 3-4), which consists of an inner cell mass, a group of cells clumped together at one end of the embryo, and the trophectoderm, a layer of thin cells (trophoblasts) forming a cyst-like cavity called the blastocoele. The inner cell mass will develop into the body of the embryo, whereas the trophectoderm will form extra-embryonic membranes that will ultimately form the fetal part of the placenta.
