what good is stem cells?

Question

Isn't stem cells bad since it kills humans embryos? What are the benefits for stem cell beside it can cure disese. What are the pro for stem cells?

Answer 1

I believe stemcell research is good because with nurther you can grow the stem cells into whichever part of the body is needed. I believe - don't quote me entirely.

Try checking some medical sites.

Answer 2

They can regenerate nerves and make paralyzed people walk again.

They don't kill human embryos - read about Adult stem cells and stem cells from Cord Blood

Asking "what are the benefits OF stem cells besides curing disease" is sort of like asking what are the benefits of antibiotics besides curing disease.

If we disregarded that part of it, we'd never use them because all they do is cause side effects.

What good is asking questions apart from provoking thought and getting answers?

This is very weird of your first question. Stem cells don't kill humans' embryos. In fact, humans' embryos become stem cells! I think you are talking about the research that needs to use stem cells. And do you know where is the most economical and conveniant way to get it? Bingo! human embryo. So, stem cell is not "bad", its the research. But I think the research is bot bad after all. The procedure to get stem cell is just suck some of the embryo cell form it when the embryo is big enough. It is kind of like taking a tissue sample from you but you are ... erm ... a little bit young. And believe me. It will not hurt you. Your cell will grow back in a couple of hours.

And the question that its benefit besides it can cure disease. I am not sure What disease you are refering to, but perhaps, blood cancer?Do you ever know what stem cell is? OK, time for a little biology basics. Our embryo can turn into every kind of cell like blood cell, neuron cell, muscle cell and something else to form us, humans. When they turn into these cells the gene that make them multi-functioning will close and left only the specific gene to work on to let the cell behave good and where they should be. Like those in stomouch, their job is to absorb food and produce enzym. It will be a total choas if those gene don't shut down. Can you imagine that you have a brain inside your lung? OK, those multi-fuctioning cell called stem cell. It is useless when we are fully develope. So they can rest inside our body and wait for their time to work like repairing our body when we are wounded. In the other animals case. they can repair their limbs! You know, the earth worm will grow back after you slice them in 2 part. For this, scientist found this kind of cell interesting. If we can control the stem cell really good. we can grow our tissue back if we got disease! Such as blood cancer. We can plant back our own stem cell that collected when we were still were an embryo and plant it back to our bone. And we can produce our white blood cell normally again! yeah!

OK, so stem cell became a reaaly hot nowadays because it is multi-functioning. Well, in short and simple. It can do everything. Our heart broken, heal it with stem cell. Our limbs were cut, or sliced, use stem cell to regrow it. the best part is, know that we cannot reproduce any neuron cell after we are mature. So that what ever happen to those who broke their spine and has to lay on bed for the rest of their life like the respectively superman Reeve Christopher, We are able to grow back our spine and walk again!! isn't this amazing. We may even gain immortallity!!! Our cell will age and after a few times of miosis, they die. So we do. But stem cell can do miosis repeatly and will not destroy their own structure. In the other way of explaination. They live forever. And if we successfully get this technology, immortallity is not a dream! A new and young body for every olds may not be a fantasy!!!

Stop dreaming. Back to reality. Stem cell is really useful.

hope this help you.

Answer 4

It is important to develop alternative testing methods for drug discovery and toxicity of
chemicals and reagents for improved reliability, reproducibility and for reducing and
replacing animal tests.no it is not bad. embryos is again produce from stem cells .morover everything has a +ve or _ve sides.
