Stem Cells: Research and Controversy
Adult Stem Cell Research
On the other hand, we could obtain an individual’s own stem cells and specialized adult also for other tissues or organs needed rebuilding. A good supply of own stem cells could be obtained from the umbilical cord at birth and subsequently retain frozen.
Therefore, the possibilities would be two: collect stem cells from an adult, or keep frozen umbilical cord at birth that can serve later as the aforementioned provision of stem cells.
Stem cells are cultured in appropriate media until the tissue is needed. After the individual patient is transplanted tissue or cultured cells needed to regenerate the diseased organ.Controversy over stem cells
The controversy over stem cell ethical debate on research of the creation, use and destruction of embryonic stem cells.
Opposition to the research says that this practice can lead to cloning and mainly to the devaluation of human life.
By contrast, some researchers believe it is necessary to proceed with investigations of embryonic stem cells because the resultant technologies could have great medical potential, and can be used excessive embryo created by IVF for donation for research.
This conflict has emerged between supporters of these investigations and the Pro-Life Movement (Pro-Life), the latter requiring the protection of human embryos. The ongoing debate has led authorities around the world seek greater agreement on the work developed in this field, noteworthy that the research of embryonic stem cells represent a social and ethical challenge.
