The Human Embryo and Embryonic Stem Cell Biology: Spotlight on Stem Cell Research On December 15, 2010, Renee Reijo Pera, PhD spoke to the CIRM Governing Board about her research studies of the human embryo and embryonic stem cells. Using time lapse video of the embryo's initial cell divisions, Pera's lab identified parameters that can accurately predict human embryo viability. These findings could improve the success rate for couples trying to have children through in vitro fertilization as well as reduce the number of embryos used in the procedure. Pera is director of Stanford's Center for Human Embryonic Stem Cell Research and Education. She was introduced by Robert Klein, chair of the CIRM Governing Board. She has a Comprehensive grant ( 1.usa.gov ) and a New Cells Lines grant ( 1.usa.gov ) from CIRM.
Embryo Biopsy Dr. Silber shows three examples of embryo biopsy, each time removing two cells from the embryo. In the first two examples, blastomeres are easily removed due to decreased compaction. In the third example, however, there are tighter connections between eight blastomeres, leading to a more difficult embryo biopsy. This is done to test the two extracted cells for abnormalities within the embryo.

Alex: i have no idea Nikki: Evan? Evan: I dont know either Nikki::still its not a bad word Brie: yes it is Nikki: NOOO Brie: YESS Nikki:NO NO NO Brie:YES YES Yes Nikki: whatever your so annoying your a little brat Brie: your one too cuz your my twin Nikki: actually let me tell you about science you see ...
Cleavage pattern, gastrulation, and neurulation in the appendicularian, Oikopleura dioica From the Springer article: Cleavage pattern, gastrulation, and neurulation in the appendicularian, Oikopleura dioica by: Fujii, Setsuko; Nishio, Takaya; Nishida, Hiroki; Two rounds of unequal cell division of B-line blastomeres at the posterior pole; the vegetal pole is at the upper left. Posterior view, the video starts at the eight-cell stage and ends during gastrulation. The B blastomere pair of the eight-cell embryo divides unequally twice--generating the smaller B1 of the 16-cell embryo and B11 of the 32-cell embryo.

Stem cells from arrested embryos and Federal Funding 1/2 of all IVF embryos stop growing. This podcast from the journal Nature includes video of more sources you can examine on the issue. I accidentally included a shot of blastomere extraction as well - beating heart cells matured from their stem cells are on other videos here. Stem cells from both these methods are available for federal funding due to Bush's EO 13435, issued June '07.

Embryo Biopsy During embryo biopsy, a single cell (blastomere) is removed from the 3-day old embryo following IVF. That cell is then ***ysed genetically to detect specific genetic defects or determine the gender of the embryo. This is termed PGD (pre-implantation genetic Diagnosis). In this video, the procedure of embryo biopsy is being performed at the Istishari Fertility Centre in Amman, Jordan.

Preimplantation Genetic Diagnosis (PGD) This is an animated video that shows the steps involved in Preimplantation Genetic Diagnosis (PGD). When a fertilized egg has grown to between the 4-10 cells, 1-2 of these cells (known as blastomeres) are gently removed from the embryo using a microsurgery technique. The genetic material (DNA) from the removed cell is then ***yzed for genetic abnormalities.

Day 3 human embryo biopsy An 8-cell human embryo with average morphology, biopsied roughly 70 hours (Day 3) post-fertilization. When indicated, a single cell (blastomere) can be removed from a Day 3 embryo and subsequently tested for inheritable genetic diseases. The embryo is returned to culture and the biopsied cell is couriered to a genetic lab. Results from the biopsied cell are generally available inside of 48 hours. The embryo is in a solution of calcium and magnesium-free media that is necessary to loosen the cell-cell junctions and isolate a single nucleated cell (no nucleus, no DNA, no diagnosis). The first pipet applies an acidified solution to the protein coat (zona pellucida) that dissolves a hole approximately 2/3 the diameter of the blastomere. The embryo is then moved away from the locally acidified area. It is also possible to use a laser to 'hatch' a slit through the zp, but not every IVF lab has access to one. The second tool is pushing a minute amount of culture media through the space in the zp to create just enough positive pressure to extrude a single cell. Using a positive-pressure biopsy technique has the advantages of being potentially very quick, unintrusive and with less likelihood of shearing cells and subsequently carrying-over potential DNA contamination between successive embryos. It has also been especially helpful on microscope-rigs with less-than-perfect optics or with poor vibration isolation.

Preimplantation-Fragmented Embryo Biopsy Day Three Cleavage state embryo
Normal embryo undergoing embryo biopsy for PGD PGD or pre-genetic diagnosis is a complexed but very successful procedure, where a single cell or blastomere is removed from a day 3- eight cell embryo and the nucleus of that cell is than fixed to a slide. The nucleus of the cell contains the embryo's chromosomes; thereby, allowing the couple to determine the chromosome make-up of each embryo, to rule-out abnormalities like Down's Syndrome or to determine the *** of the embryo, for couples wanting to have either a boy or a girl. For more information about PGD for *** selection or to rule-out chromosome abnormalities please visit our web site at www.acfs2000.com and read about PGD under ART services.
