has come under many debates both in the medical community and in Congress. The ESC and EGC debate is best stated by Senator Sam Brownback’s testimony on stem cell research. “We on this panel‚ I believe‚ all in this room‚ believe that an embryo is alive. The central question remains‚ is it a life? Or is it a mere piece of property to be disposed of as its master chooses?” (Wildmoon) The Controversies surrounding Stem Cell Research In stem cell research‚ there are three sources

On August 9‚ 2001‚ President George W. Bush announced to a national audience his decision and new policy on stem cell research. President Bush explained to the United States how he would not allow federal money for new stem cell research. Federal money could only be used for existing stem cell lines. For any new stem cell research‚ the money must come from the private sector (Ruse‚ 11). This controversial decision is still a widely debated topic that is in the forefront of the current political

Step one‚ thirty-six hours after fertilization‚ embryos are given 8 minutes exposure to x-rays‚ a few eggs die‚ a few divide in two‚ most divide in four‚ some divide in eight. The next step‚ wait two days is then the embryos are chilled; so a few eggs die‚ a few divide in two‚ most divide in four‚ and some divide in eight. Step three. The embryos exposed to near-lethal

adverse effect on the hatching success of eggs and survival rate of the embryo. The pesticide was assessed for its toxic potential and it was hypothesized that in the exposure water it will be harmful to the development of zebrafish embryos and our findings prove that a very low concentration in the water in the laboratory condition does have an impact on the development of the fish embryo. In the embryonic stage‚ the dead embryos significantly increased in response to the pesticide concentrations

Embryonic Cloning Embryo cloning is an area of stem-cell research that focuses on embryos and is the process of harvesting human stem cells for scientific study. Embryonic stem-cell research is sometimes also referred to as research cloning and therapeutic cloning. Cloning is a general term that scientists use to describe various processes for duplicating biological organisms and is an ethically controversial area of biomedical research. The debate regarding cloning is centered mainly around the

The process of inserting the sperm into the egg (intracytoplasmic sperm injection) is done by the embryologist. They also prepare the embryo for transfer into the patient‚ making sure the embryo is in good shape‚ and cryopreserve any other embryos that will not be used during the process.

Once multiple embryos have been created they are placed back into the mother’s womb‚ where they develop until they are born. 1 The embryos are surgically removed through IVF then are placed into a petry dish to be fertilised by the donated sperm.

These stem cells are used to better understand and treat diseases. They also help scientist understand how diseases occur/develop.
