Stem Cells & Healing?

Adult stem cells are undifferentiated cells, found throughout the body after embryonic development, that multiply by cell division to replenish dying cells and regenerate damaged tissues.

Okay, I see how you went down the wrong path. That sentence is not actually untrue, but it's very misleading if you don't know a lot about biology already.

Stem cells are not so much found throughout the body, as in a number of specific places. (There are very small numbers of stem cells more widely distributed, but they don't do very much - a point I was corrected on earlier.)

So the stem cells in the bone marrow produce blood cells, as discussed. Stem cells in other places provide some limited ability to produce new cells, such as neurons in the brain.

But this is limited. The only organ that regenerates itself to any significant degree in adult mammals is the liver. If you lose half your liver (or donate half of it to someone with liver failure) you can regrow it. But you can't do that with any other organ, and no other mammal can either. And your liver can't regenerated into anything else; it can only regrow itself.

Skin cells can likewise produce new skin cells - but not anything else.

This differs from, for example, neurons, which for the most part die and are lost. And heart muscle is unlike most other muscle tissue and has only very limited ability to heal damage.

We haven't lost any regenerative ability due to modern lifestyles or anything else; our species never had it; as far as we know, no mammal ever had it. Stem cell research is aimed at giving us new treatments that we simply never had before.

Even autoimmunity(even beta cell damge), iron defficiencies etc. can have surrvival benefit. I try to understand hidden net survival benefits in all body's physiological actions. Probably, non-damaging actions of a mad person may be meant in some benefit to reverse his madness. Try you may feel better.:)

In nature, we can notice that birds & annimals do practice fasting & resting in dark corner for some time and then get naturally cured. This somewhat suggest something is hidden in these natural practices because we also get aversion to food & liking to take rest on many diseases & disorders. Someone suggested PNS, good sleep suppot stem cell activities.

What animals practice fasting, other than humans? There's the case of hibernation (which I think is what you're trying to get at), but that fasting is out of necessity, not because it heals the body in any way, and humans are not capable of hibernation.

Hibernation is different from avoiding food and resting. It's an entirely different process - the metabolism of the animal slows down, along with heart rate. For example, I recently had all four of my wisdom teeth pulled through surgery. I've slept a lot lately and have not really have had the urge to eat - unrelated to my ability to eat, I can eat soft foods like pudding and soup with no problems - but that's an entirely different kettle of fish than hibernation.

If you don't mind me asking, what is your first language?

This has been asked before, in the hope that someone might be able to explain things to him in his own language (and indeed in the hope that Kumar might be a little more coherent in his own language). He wouldn't say.

I had also provided this link. It is not related to body's natural mechanism to enhance/reverse & properly use stem cell syste.

Yes this treatment is yet half cooked but it should have logic/possibilty--may be our miss due to lost ground.

Still, many so justified evidances can be half cooked & many certified things in mass use can be harming whose list can be long. Eg. evidances & allowance based on few years studies without life long DBPC studies for those diseases which have life long impact & usually whose complications come late in life. We can't justify absolutely, what caused those complications--disease or interventions. Pollution creaters, global warming tools, alcohol & tobbaco allowance, unnatural things to us introducers etc. can come into ultimate killers. Homeopathy may not be so horrible in comparisn to these. Moreover today's educated & well informed people should not be so idiot or gullible.

Thanks for good explaination.

Sorry, but so many odds, contradictions, confusions & unclarities are there in current understandings. It is difficult to justify valid or invalid.

Quantity should not matter as Stem cells are capable to multiply in any quantity. Why they don't & why we want outside stem cells is a big question to me?

So the stem cells in the bone marrow produce blood cells, as discussed. Stem cells in other places provide some limited ability to produce new cells, such as neurons in the brain.

Yes it is there in one link. Even nerve has regerative capacity(read lonk provided). But what hinder it, we should try to understand to enhance & fully use this system.

It is true that homeopathy is less directly harmful than, for example, smoking. The broader picture is less clear, since homeopathy's negative imact is diluted by the effectiveness of real medicine.

Moreover today's educated & well informed people should not be so idiot or gullible.

If stem cells multiplied uncontrolled, that would be just like having cancer everywhere at once. We'd all die. So there are control mechanism, and those mechanisms have evolved in such a way that the regenerative abilities of stem cells in mammals are very limited.

So stem cell research is aimed at finding ways to activate stem cells for very specific functions - to regrow a kidney, for example.

That's what stem cell research is all about. We can't enhance the stem cells in the body, but we should be able to take them out, tinker with them, and then put them back where they're needed. It's complicated and difficult work, though, and not ready yet.

Are we not losing on account of modern practices--many pollutions, stress, unnatural foods to us, global warming, addictions etc.?

People know what they are taking & what they are experiancing. Simply for precautionary sake, people can opt for lower potenties & where there is a gap and there is not hope.

If seeds are there, soil quality matters for their growth. We can try improving our soil.

People what to believe in magic. The fact that they feel better does not make it true. Ever heard of the logical fallacy post hoc ergo propter hoc? It means "after this, therefore because of this", and is the fallacy of assigning a cause just because it came before. People who point to homeopathy patients and say "See? They got better! Therefore, homeopathy works!" are making this exact fallacy. Scientific studies all show that homeopathy is no better than a sugar pill. It does nothing at all.
