blastocyst biopsy

blastocyst biopsy

A biopsy performed after the blastocyst differentiates into 2 morphologically distinct cell lines: the trophoblast and the inner cell mass of about 60 cells. Blastocyst-stage biopsy for pre-implantation genetic diagnosis is performed on day three of in vitro culture, which allows the developing TE to protrude after blastulation.

Blastocyst biopsy provides significantly greater cell amount compared to polar body/blastomere biopsy, but this method demands cryopreservation owing to the time required for genetic analysis.
Until 2010, early embryo biopsy was the most frequent aspect of genetic analysis (1999-2009: 26.284 cycles; 2009-2010: 4.918 cycles) compared to polar body (1999-2009: 3.750 cycles; 2009-2010: 997 cycles) and blastocyst biopsy which was used the least often (1999-2009: 105 cycles; 2009-2010: 6 cycles) [28].

These methods range from biopsy of polar bodies to single-cell blastomere and routine two-cell blastomere biopsy--and, more recently, to blastocyst biopsy. The impact of these various embryo manipulations has yet to be fully considered.

Blastocyst biopsy has also been suggested in this regard, but since the blastocyst has a higher degree of chromosomal mosaicism and since trophectodermic cells could be mistakenly taken out (they can differ chromosomally from the inner mass cells), Day-3 biopsies prove more accurate (9).
