Embryonic Stem cell research is the same as harvesting body parts. If as a society, we find harvesting stem cells from a fetus an acceptable procedure, then why not harvest the liver, kidneys, skin, bone and other parts? Perhaps we can evacuate the fetus's brain prior to birth and then market the body parts. By some estimation, such a body could be monetized in excess of $240,000 per developed fetus. While we are considering this, perhaps we can follow China's lead and start harvesting executed prisoner organs. Going one step further, perhaps we can consider the value of each person to society and perhaps those individuals deemed substantially less valuable than others can be required to "give parts" for the embetterment of society. Should we really concern ourselves with the notion that every person is equal under the law and that each person has their own goals and aspirations, desires and pains? Does that curious notion that "All people are created equal" have any place in our modern society?

The practical definition of a stem cell is the functional definition - a cell that has the potential to regenerate tissue over a lifetime. For example, the gold standard test for a bone marrow or hematopoietic stem cell (HSC) is the ability to transplant one cell and save an individual without HSCs. In this case, a stem cell must be able to produce new blood cells and immune cells over a long term, demonstrating potency. It should also be possible to isolate stem cells from the transplanted individual, which can themselves be transplanted into another individual without HSCs, demonstrating that the stem cell was able to self-renew.

I took my first loans when I was not very old and it supported my business a lot. But, I require the short term loan again.
