Preimplantation genetic diagnosis (PGD) involves testing for specific genetic conditions prior to the implantation of an embryo in the uterine wall. This form of genetic screening has been made possible by the growth of in-vitro fertilization (IVF) technology, which allows for the early stages of development to occur in a laboratory dish rather ...
Although PGD was originally thought to be a mechanism to discard embryos affected by a particular disease , some couples are now using this technology to actually choose embryos affected by a particular disease to be implanted in the uterus. Such cases have occurred with parents with dwarfism and congenital deafness.
The purpose of PGD is to identify what are considered to be abnormal embryos in order to select the most desirable embryos for implantation. Diagnosis is comprised of two steps: extraction of one or two cells from an IVF-produced embryo, and application of the PGD test. PGD is important to embryology because it has advanced IVF results ...
Because the PCR reaction is very sensitive, it requires pure, high-quality DNA samples from only one cell. Although not very common, errors can occur and result in misdiagnosis leading to the discarding of a normal embryo, or an affected embryo being transferred into the mother.
Fluorescent probes are added to the DNA, which then bind to specific chromosomes in a technique called fluorescence in situ hybridization (FISH). These fluorescent markers allow the chromosomes to become visible, enabling researchers to determine not only the sex of the embryo, but also the pairings of the chromosomes.
meiosis = a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
cleavage stage = the division of cells in the early embryo. some center perform analysis on polar bodies that are extruded from the egg during meiosis. polar bodies = each of the small cells that bud off from an oocyte at the two meiotic divisions and do not develop into ova.
