Cleaving human embryo from IVF

3 cell embryo from in vitro fertilization in the process of cleaving
The upper cell is elongated - we caught it cleaving, dividing into 2 cells (to make a 4 cell embryo)

A 4-cell embryo (different patient) that is done cleaving from the 3 cell stage
Cumulus cells from the ovary are seen at 6 to 8 o'clock
All 4 cells are visible, cell at 4 o'clock is slightly above the plane of focus
