Very good question put by Dr. Sawant. probably in these research we are giving shapes to our cruel thoughts into practical action, therefore, it may achieve functional immorality.

There is nothing cruelty about seeking new methods to cure diseases or improving longevity. As there there is nothing new in the proposal as humans have always tried to increase lifespan and solve theraputic problems. We have controlled so many diseases and reduce the pain, particularly for diseases like cancer through research. Immortality will definitely bring some challenges but human can overcome these challenges.

Every thing man can imagine, man can do

Dear

Amr, Please add your more thought how stem cells can help.

OK,I think cells has to communicate with each other through signal transduction and the key for this is the precise regulation of the Wnt signaling pathway,and the very first signal comes not from the cells , but from the extracellular matrix,that we are ignoring it, so we have to change our way of thinking a little bit.

Thanks Amr.

Very good question.I am not at all from this field, but in some fiction book I read something very interesting which I will share.Theoretically speaking with the help of stem cell we can go for organogenesis(like growing organ outside human body). There is a possibility in future, where we will be able to grow organs from stem cell like if someone has diabetes, we may be able to grow pancreas for that particular person using that person stem cell. In that way there is no way that patient can reject that particular organ because that organ will be made by his own stem cell. This is totally fiction but in future anything is possible.

There is research going on with Stem cells and it is getting better and better. I have added some reference.

Immortality ??? You gotta be kidding ! Look around ! There's no such thing in nature. Immortality, fountain of youth, super food, etc are all just examples of how superficial and greedy humans are. We want everything even though what we really need is not much at all. All we need is just simple common sense. How come nobody has ever done research or come up with something that will change our bad behavior towards one another ? Nobody has ever figured out or found the molecules of "love" or "hate" so we can make more "love" molecules and let the T cells eat up all the "hate" molecules. Wouldn't that be great? Then, we can live forever if we can get rid of hate. I welcome all of the medical achievements to make human suffering less, but "immortality" will not accomplish that.
