Sykes Published The role of biotechnology in the forest products industry is expanding beyond the pulp and paper industry. Applications that can contribute to forest sustainability include genetic engineering and phytoremediation. Genetic engineering makes it possible to modify forest trees for desirable traits, such as disease or pest resistance, and to replicate these improved trees by cloning. Save to Library. Create Alert.

Blastomere biopsy also known as embryo biopsy is a technique that is performed during IVF when an embryo has reached the six to eight cell stage about 72 hours or day 3 of embryo culture. One or two cells, or blastomeres, are separated from the rest of the embryo and removed from the zona pellucida which is the shell surrounding the developing embryo.

After removal of the cell sthe developing embryo is placed back into the culture media and returned to the incubator where it can resume its normal growth and development. In this picture, you can see the aspiration pipette the glass tube on the right gently pulling the single blastomere off of an 8 cell embryo. However, a recent study suggested that a biopsy performed at the blastomere Haarvesting was responsible for a decreased chance that the embryo would be able to implant into the uterus later.

After obtaining cells from the embryo, they can then be analyzed using a variety of different techniques.

Short Story

This, each of the eight cells should be identical. This is called mosaicism. Mosaicism is important when performing preimplantation genetic diagnosis — PGD via blastomere biopsy because it means it is possible that the cell that is biopsied may not be representative of the entire embryo. For example, if during PGDa blastomere biopsy is performed and the cell that is obtained is abnormal, Embryo Harvesting And Genetic Manipulation entire embryo would considered Harvesing even though the remaining cells in the embryo may be normal.

The opposite is also true. Learn more about polar body biopsy Learn more about trophoblast biopsy.
