Trophectoderm biopsy in human blastocysts

1 Oct 1990

Abstract excerpt

Trophectoderm biopsy was carried out on 47 human blastocysts. A slit was made in the zona pellucida opposite the inner cell mass by micromanipulative techniques. The human blastocyst zona offered more resistance to slitting compared to that of the mouse. After 18-24 h, controlled herniation of the trophectoderm cells was observed. These cells were biopsied when the diameter of the herniation was approximately...
