Stem Cell From Skin Cell Discovery
Researchers are reporting in the journals Cell and Science that they've transformed human skin cells into pluripotent stem cells, which could revolutionize medicine and potentially lead to cures for numerous diseases.
The medical ethical debate of using cells from human embryos to create, grow, and develop implanted replacement cells for damaged cells in living humans, may be over and with good reason.It was believed that the only way to get cells that could be used the create cells that function for different parts of the human body was from material that held the beginning of life. These cells were believed to be the only cells that were “Pluripotent” – the ability to be programmed to become a cell that would function for the specific function the group of cells to be implanted or replaced.
Stem (pluripotent) cells can now be converted from living human skin cell tissue. The skin cells, once converted, act as dynamic as original stem cells harvested from embryos but with some greater advantages.
Let us set aside the fact that once an embryo is compromised when the stem cells are harvested from the embryo (this means that the embryo will not be able to develop into a new human life), the stem cells that are used to grow the replacement cell structures, once implanted, stand a chance of being rejected by the human body in which the repair takes place.When stem cells are created from the skin of the human host patient and then used to create the specific cell structure needed to repair a damaged area of the same human patient, there is no rejection of the implanted repair cells.
Embryonic stem cells are valued above all others, because until now they are the only kind remarkably shown to be truly "pluripotent", that is having the capacity to become any of the 220 discerning types of cell in the human body. They have the undeveloped potential to generate new heart, liver, brain, muscle and bone tissue, and replace diseased or damaged tissue in people who are ill with cardiovascular, Alzheimer's, Parkinson's and a whole range of the other diseases including diabetes.
The other advantage of the new method is the fact that using cells drawn from the patient's own skin, the stem cells can be customized to the patient, bringing numerous benefits, such as the elimination of immune system rejection.Further, even if the source skin cells come from a non-patient host show signs of rejection when implanted in the patient ... this is a far better solution than compromising an embryo and the potential of a new human life for the same result.Stem-cell research has the potential to cure such dreaded diseases as Parkinson's and Alzheimer's, and could provide solutions to spinal cord injuries, leukemia and juvenile diabetes. Scientists are years away from knowing if human skin cells will actually work as a substitute.
