Are Stem Cells A Second Chance At Life or Controversy? A Review on the Debate Abstract Over the years‚ there has been a growing debate between scientific researchers and moral advocators over the sources and didactic implementations of stem cells. While the practicality of stem cell use in the human body seems to be endless‚ the dispute cycles around the morality of the issue. This paper will demonstrate three main points: the description‚ implementation/research‚ and morality

Research Once an egg cell is fertilized‚ it will undergo division and become an embryo. As an embryo‚ stem cells that are able to becoming many types of cells in the human body. Scientist research by getting embryos in two ways. A couple’s sperm and eggs are fertilized on a experimental dish where the egg develops into embryos‚ which after are implanted in the female. The second way in which scientists get embryos is therapeutic cloning. This technique merges a cell with a donor egg. The nucleus

On the other side are those who insist that stem cells can only be collected by killing embryos by murder. Before 1998‚ research on stem cells-mostly from non-controversial sources such as bone marrow and umbilical cord blood-was framed in highly technical terms‚ focusing on the release of the latest scientific findings or emphasizing the

cells has sparked controversial debates all over the United States. What makes them so controversial? It is where they come from. Embryonic stem cells are “blank cells” harvested from an early stage embryo that have the potential to turn into any kind of cell in the human body. Usually‚ these embryos are unused from in vitro fertilizations and would otherwise be thrown away. Embryonic stem cells have the potential to treat people with diseases‚ such as Parkinson’s‚ diabetes‚ and leukemia as well

mixing the woman’s egg and the man’s sperm outside of the woman’s body‚ usually in a petri dish. Invitro fertilisation literally means ‘fertilisation in glassware’. If the fertilisation is successful‚ the formed embryo is transferred to the woman’s uterus after 2-5 days. Usually‚ multiple embryos are transferred to improve chances of implantation and pregnancy.

CELL THEORY – STEM CELLS Stem cells are a large focus of study in today’s biomedical world. “They are cells that exist in an undifferentiated state‚ and transform into differing tissue types depending on what the cells surrounding them are‚“ (National Institute of Health‚ 2012). Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition‚ they also serve as an internal repair mechanism inside many tissues‚ dividing without

JEANETTE JOHNSON A fruit results from the maturation of one or more flowers. The ovule producing part of the flower forms all or part of the fruit. Inside the ovary/ovaries are one or more small eggs‚ where the embryo sac contains the egg cell. When the female embryo sac joins with two male sperm these ovules become seeds. (Biology Online‚ 2005) Each fruit is made of certain acids‚ vitamins‚ fructose‚ proteins‚ starch‚ and cellulose. These are mixed together to form certain tastes

or dead is frozen‚ small ice particles usually grow inside cells which can sometimes result in severe damage to cell structure. With that being said scientists normally remove cells from the body of an animal or human that they want to preserve by freezing them then they soak the cells in a special kind of antifreeze to prevent cell damage. Let’s use mice cloning for an example. Scientists have been cloning mice from other mouse that have been frozen for nearly 20 years. They removed the nucleus from
