Blastocyst development stage a range from 1 6 with 5 being the most developed 2. Embryos are cultured in the first medium from the zygote day 1 stage until day 3.
Just like you though the new individual. This stage is followed by blastocyst hatching and implantation. The primary benefit to the patient of using blastocyst stage embryo culture is that fewer embryos need be transferred into the patient because each day 5 embryo has a higher chance of implanting than a day 3 embryo does. Blastocysts follow after the morula phase which is when the egg becomes a solid ball of cells until day three. The stage of embryonic development when a gastrula is formed from the blastula by the inward migration of cells. One day after fertilization the embryos are observed under the microscope.

Embryos are cultured in the first medium from the zygote day 1 stage until day 3. Embryonic stem cells were first derived from 35-day-old mouse embryos Evans and Kaufman 1981.
