The discussion centers on the potential for extending human lifespan through cell preservation and regeneration. Participants clarify that aging is primarily due to weakened cell function and improper protein production, leading to diseases like cancer and Alzheimer's. The conversation explores the concept of using stem cells, particularly from cloned embryos, to replace unhealthy cells, as these cells could theoretically avoid rejection by the body. However, challenges remain, including ethical concerns surrounding stem cell research and the complexities of cell integration and replacement in various tissue types.The idea of merging cells or using genetic engineering to enhance cell function is debated, with participants noting that while stem cells can differentiate into various cell types, the body’s response to foreign cells complicates potential treatments. The discussion also touches on the limitations of current research and the need for further understanding of aging mechanisms. Overall, while the theoretical potential for indefinite lifespan exists through advanced cell replacement techniques, significant scientific and ethical hurdles must be addressed before such possibilities can be realized.

so could you currently get stem cells from cloned embryos?

Hypothetically how long of a lifespan could you get from the ability to replace all cells in the body whenever necessary?

Sorry, I'm kind of confused

Do they get stem cells from cloned embryos currently?
Will they in future?

How long of a lifespan could replacing cells (realistically) lead to?

The histocompatibility issue would complicate things lots right?

Thanks

You need to learn to stop double posting.

How I see it, you want a nice feature like Weapon X (Wolverine).
In my opinion, until we throw away ethics, morality, and all that other crap, we won't get far. The government restricts much of what people do to obtain power.

This is why I find neurological research more interesting. While you have bio-chemists and other people out there figuring out how to use cells, you could probably enhance your brain with cybernetic enhancements thus allowing you to learn at an exponential rate and retain memory. Such things at this time are primitive because people keep calling this the age of Biology. This is the age of biology and perhaps next century will be the age of neurology. However, I think that about 50% of the population should split right now on their scientific viewpoints.

People for however long they can live will be working super hard on such a project. I believe that back in 1993 a woman figured something out on cell manipulation and spent about 12 years contemplating the releasal of her scientific find.

Which would you rather do? Learn ultimately faster and then be able to create regenerating body parts with control of your biological clock or sit around with test tubes jotting down paper work with cells?

(I edited this post a few times btw)

I just double-posted because I wanted it to show up on the thread thing (Which is viewable before the thread itself is) (Which says when the last time somebody posted is or something...) that I had updated what I wanted to say (Sorry I guess I still shouldn't have double-posted)

I agree that there are a LOT of areas where a LOT of research/knowledge-gaining should be done. I wish we knew more about genetics. But I also wish we know a lot more about a lot of other stuff. (Like for example cybernetic enhancements)

BTW what is it that the woman discovered

But what I want to know is:

Do they get stem cells from cloned embryos currently?
How long of a lifespan could replacing cells (using cells from cloned embryos) (realistically) lead to?
and other things like that

Thanks

*hopes Monique will come back*

What tissue types are there? (In the human body)
How difficult,etc would it be with other tissues types?

If you don't really know all the answers to these questions, then I can understand that you are very interested in Biology to ask them.

I may be making an arse of myself with this post, but I'm going to assume that someone that has to ask about all of the tissues within the human body doesn't have a basic understand of human biology.

I suggest that you go to a local library and pick out a good book around 400 pages that has to do with Biology. Don't worry, I've found that the more you read in life, the faster you become. That's why I can read really quick. I read stuff online all the time. College peers are amazed with my reading speed.

There are two books I'm going to recommend to you.

One will give you an introduction to human biology.

[URL[/URL] Biology : Concepts and Current Issues (3rd Edition) (Paperback)
by Michael D. Johnson][/url]

After you understand some of the concepts of Human Biology, then you will have a basic understanding of biology. From there you should go to Microbiology. Hopefully you may get a bigger picture from there.

The other will stimulate your brain giving you philosophical viewpoints into the world of biology which will allow you to have a broader view on things.
[URL][/URL]

It may be dated but it doesn't cost that much. It will take time to read and dictionary.com and other dictionary sources are great. Since online communities have been built you may be able to review more.

In case you have more trouble with biology, you could always visit [URL]http://www.en.wikipedia.org[/URL] which may have an entry on the biological specimen you are looking at for information. I use wikipedia most of the time for research.

------edit--------

Also, searching on [url=http://www.google.com]Google[/url]for things such as ("stem cells" cloning embryo immortality regeneration) certain keywords can bring up interesting articles and may help you find an answer more quickly when people aren't around to respond.

okay I found out it's possible to get cells/stem cells from cloned embryos but

How long would it (Hypothetically) be possible to live for using stem cells/other types of cells from cloned embryos to replace unhealthy cells? I guess that's my only question at the moment

thanks :)

I guess I wanted to know about using stem cells/other types of cells from cloned embryos to replace (Whenever necessary in order to live...the longest lifespan (Currently unknown to me) possible by doing that) the cell groups that form these 4 types of tissues

1. Epithelial Tissue - The cells of epithelial tissue pack tightly together and form continuous sheets that serve as linings in different parts of the body.* Epithelial tissue serve as membranes lining organs and helping to keep the body's organs separate, in place and protected.* Some examples of epithelial tissue are the outer layer of the skin, the inside of the mouth and stomach, and the tissue surrounding the body's organs.
2. Connective Tissue - There are many types of connective tissue in the body.* Generally speaking, connective tissue adds support and structure to the body.* Most types of connective tissue contain fibrous strands of the protein collagen that add strength to connective tissue.* Some examples of connective tissue include the inner layers of skin, tendons, ligaments, cartilage, bone and fat tissue.* In addition to these more recognizable forms of connective tissue, blood is also considered a form of connective tissue.
3. Muscle Tissue - Muscle tissue is a specialized tissue that can contract.* Muscle tissue contains the specialized proteins actin and myosin that slide past one another and allow movement.* Examples of muscle tissue are contained in the muscles throughout your body.
4. Nerve Tissue - Nerve tissue contains two types of cells: neurons and glial cells.* Nerve tissue has the ability to generate and conduct electrical signals in the body.* These electrical messages are managed by nerve tissue in the brain and transmitted down the spinal cord to the body.

Did Yomamma say that stem cells would work fine (to live indefinetly?) if we were allowed to use them? (From cloned embryos/other embryos)
 
  • #41
I said they could repleced damaged body parts, or non-functioning body parts
 
  • #42
At this point in time? Or would more research need to be done before they could do that?
