What Are Stem Cells?
January 26, 2009 at 3:25 PM by Cafe Kristen - Comments (8)
A big story over the weekend was that the Food and Drug Administration (FDA) approved the first human clinical trial of embryonic stem cell therapy in the world, according to CNN.
Honestly, I didn't understand this news any more than I understand how to run my DVD player.
After reading four different articles, my take is that the FDA okay'd the use of embryonic stem cells for a handful of people with severe spinal cord injuries--meaning, people who are paralyzed. These people who agreed to be in the study will receive stem cell injections that might help their bodies and brains communicate again--meaning, they hope to be able to move more or maybe even walk. When these stem cells were given to rats who'd lost control of their hind legs, the rats were able to walk and run again.
We hear a lot about the hot button topic of stem cells. But the issue is really confusing. Here's what I gathered from CNN and other online sources.
Embryonic stem cells have the potential to turn into any organ or tissue in the body. Stem cells have this ability for a very short time. Just a few days before the embryo would implant, it starts to develop into specific cells that will turn into skin or eyes or other parts of a developing fetus.
Where do stem cells come from?
Researchers use embryos that have been created in fertility clinics by taking an egg that is fertilized in a petri dish. Stem cells are not removed from embryos that have been conceived naturally. The embryos used for research are not intended for making a baby, and researchers have to get consent from the parents in order to use their fertilized eggs for study.
When the embry is four or five days old, scientists extract the stem cells and put them in a petri dish. Upon removal of these cells, the embryo is destroyed. This is why some people oppose this research.
Why are scientists so determined to do research with stem cells?
This is a study of regenerative medicine. Besides patients with spinal cord injuries, stem cell therapies could benefit people with Alzheimer's, Parkinson's and multiple sclerosis.
Why are politicians so involved?
They have their own ideas and beliefs. George W. Bush limited stem cell research in 2001. Barack Obama has declared his support of stem cell research.
The group All About Stem Cells has a wealth of information, including new developments in the science of stem cells. It's carefully monitored for factual stats.
CafeMoms were vocal about the stem cell news over the weekend. You can see some responses on How Do People Feel About Stem Cell Research? in the Answers section.

I have to agree with you, Rana. I think that there is a horrible misconception when it comes to Embryotic stem cells. People hear Embryotic Stem Cell and they automatically assume that the embryos come from abortions. That is false.
the problem is they are still creating a life [embryo] and then throwing it away when they are done with it. whether or not the intention was to create life, they still are creating it and then disposing of it. i am completely opposed to stem cell research, espeically when adult stem cells have done much more than embroynic stem cells.
Thank you CafeMom for taking the time to explain a little about this HUGE news. The CNN link was a good BRIEF primer on stem cells. If anyone is interested in more information, I have it all laid out in the group All About Stem Cells. You can read and learn without joining the group!
I'm with AgentBrez, especially when there has been more successful research done with stem cells from human fatty tissue. Hell, I'll be a lifetime donor for the fatty tissue!
If research with human fat stem cells is more successful than embryonic stem cells, then quit killing babies, save some money (fat is much more accessable than embryos), can the controversy, and move along.
Rana made a great point about either freezing an embryo and throwing it out later only to waste that life, or use the life for good by giving an otherwise crippled infant, child, or adult a chance to walk again, or cure an otherwise life changing and in some cases killing disease or ailment. I feel that those opposed to this have never held an infant that has only a limited life, or they'd not be opposed to any research what so ever, especially a research that uses something that'd be thrown out otherwise to save and change their babies life. I hope this research goes on, and helps many :-)
since my husband is paralyzed and i would love that this could help him and so many in his type of situation. I fully support stem cell research!

I feel that considering the egg would otherwise be frozen forever or destroyed, the idea of throwing out something that could potentially save countless infant or adult lives for the rest of our species' life makes it fantastic research. Really, not using something we have available only hurts people.
