What is stem cell research?
Hi. im doing a project at school about stem cell research, so could anyone tell me what stem cell research is.
Answers:
stem cell research is research on stem cell which are mainly divided into 2 categories: adult stem cells- multipotent (able to differentiate into masses cells but of closely related family of cells) and embryonic stem cells - pluripotent (able to differentiate into any class of cells). stem cells are use for medical purposes and cloning Source(s): http://en.wikipedia.org/wiki/Stem_cell
Every part of your body is made up of cells. Your brain, you skin, your heart, your kidneys, even your bones. All are made up of different kinds of cell, specialized to do one job.
Your body 'renews' itself. Cells die and are replaced by their neighbors. In seven years your body is completely new, every single cell has died and be replaced.
The thing is, though, that cells can only sort cells like themselves. Bone cells trademark more bone cells, liver cells make more liver cell, etc. So if you have a disease where an organ can't reproduce its own cells, you're contained by trouble.
Well, when a baby is developing inside the womb, it has a kind of cell that can develop into any description of cell. This is obvious if you think about it. An embryo starts out as a single cell, the mother's egg, and ends up beside all the organs of a human being--heart, lungs, eyeballs, muscles, etc. So there has to be the power for a cell to develop in several different directions.
A few years ago some scientist got the idea of doing research to see if these cell could be used to help people with enduring kinds of diseases. Alzheimers disease is a good example. It's caused by cell dying in the brain, which the brain can't replace. Paralysis is sometimes caused by injuries to the spinal cord which the body can't repair. There are dozens of other really horrible diseases that could be helped.
Now, contained by the US there are many clinics where they do IVF, in-vitro fertilization. Couples who are have trouble getting pregnant, they go to one of these clinics where they take a few eggs from the woman, a few sperm from the man, and they seize them together in a petri dish. They watch these fertilized eggs and as they develop they implant a few within the mom-to-be. Usually they make more fertilized eggs than they need. The rest go surrounded by the trash! Christians believe a fertilized egg is the same as a person, and they protest abortion, but I have never hear Christians criticize the destruction of leftover embryos in IVF, of which there are thousands every year.
So the perception was to use some of these leftover embryos to make stem cell, to use for research. This is unpopular with Christians, even though they don't mind them just going in the trash. To me this is more of a political item than having to do with religion.
President Bush banned federal funds for stem cell research. Not the research itself, basically the fed. govt. paying for it. Most of this kind of research is paid for near federal funds. This was an unpopular decision with even oodles Republicans, like Nancy Reagan, whose husband, ex-president Ronald Reagan, died with Alzheimers. Obama has restored funding.
Stem cell are cells found in most, if not adjectives, multi-cellular organisms. They are characterized by the ability to renew themselves through mitotic cell division and differentiating into a diverse range of specialized cell types. Research in the stem cell grazing land grew out of findings by Canadian scientists Ernest A. McCulloch and James E. Till in the 1960s The two broad types of mammalian stem cells are: embryonic stem cells that are isolated from the inner cell mass of blastocysts, and full-grown stem cells that are found in adult tissues. In a developing embryo, stem cell can differentiate into all of the specialized embryonic tissues. In adult organisms, stem cells and progenitor cell act as a repair system for the body, replenishing specialized cells, but also maintain the average turnover of regenerative organs, such as blood, skin or intestinal tissues.
Stem cells can now be grown and transformed into specialized cells near characteristics consistent with cells of various tissues such as muscles or nerves through cell culture. Highly plastic full-grown stem cells from a variety of sources, including umbilical cord blood and bone marrow, are routinely used in medical therapy. Embryonic cell lines and autologous embryonic stem cells generated through therapeutic cloning own also been proposed as promising candidates for future therapy.
Stem cell research is the research of stem cells. Stem cells are cell that have not formed into a specific type of cell, so they can be changed to fit our needs.

duh Source(s): my mom does research on stem cell
hahaha no joke
