New Hope in overcoming a variety of increasingly deadly diseases revealed by stem cells or stem cells. Now, this method can be performed through the skin cell.
A number of major questions about stem cell method as a new treatment for the disease began to lift. The result, researchers were able to find differences in methods of stem cell - as a cancer treatment. Nevertheless, further steps are still required to make use of research as a therapy.
"To answer these questions, need further research that is still going to last long," says stem cell researcher from the Johns Hopkins School of Medicine, Dr. John Gearhart.
As with previous studies that used delayed. This research takes a long time as a continuation of previous research. For example, trying out ideas to cope with cysts in humans or animals based on research 18 years ago.
Overall, genetic therapies to repair or replace the genetic imperfections. This research has spent more than 15 years without making progress.
"At least, funding is a wedge issue in this study to test the new cells," said chairman of the National Institutes of Health's Stem Cell Task Force Story Landis.
Now, research on stem cells is growing. One is that cell is able to morph into any cell types in the body. Researchers need time to find a way to produce embryonic cells that carry the genes.
The results of this study at least can be used to create transplant tissue for treating disease. While in the short term, these cells will serve to replace damaged tissue and cell colonies capable of replacing cells that are vulnerable. Until researchers can use such cells for medical purposes.
Researchers are testing whether this expensive treatment is shown to be useful to patients. Research using the latest techniques so that it feels more recent mudah.Teknik using skin cells without using embryos as a whole.
"This study used genetically capable of manipulating the cells," said researchers from Stanford University laureate Paul Berg saying that this announcement is still too premature.
He added that the results of this research is ethically admirable. Indeed it is still unclear since it is the first step. A fundamental question is answered similar iPS cells or embryonic stem cells to determine human behavior and the use of embryonic cells. This research also spent nearly a decade.
"My guess is that we will find a significant difference," said Dr. Robert Lanza of Advanced Cell Technology who tried to produce stem cells from cloned human embryos.
Further, he disclosed, is very surprising if these cells can work on all the tricks as well as gain from the embryo.
Another big question is how to make iPS cells with another road.The breakthrough technique of treatment using skin cells with viruses carrying the genetic quartet. The virus would disrupt the DNA of skin cells, when this condition occurs a risk of cancer. Now, to stop it by creating transplant tissue to humans. Researchers have the idea to make iPS cells without viral DNA and disturbing.
"The issue of cancer risk should be able to solve problems quickly, possibly for several years," said Co-director of the Harvard Stem Cell Institute Doug Melton.
Then, iPS cells can be used in the research laboratory to determine the root causes of genetic diseases or for selection of drugs. The whole idea of using embryonic stem cells or iPS cells for the treatment of diseases such as diabetes and Parkinson's disease through the transplantation of itself is far from proof. IPS cell researchers still need to work into the correct network and use that network to work to care for the sick.
