Unmasking of cancer in the first phase, with the help of new stem cells induced
The ability to identify early stages of cancer is an important goal of biomedical science.From flattery healthy and diseased human bone marrow to become embryonic-like, a team of Wisconsin scientists has paved the way to observe the appearance of cancer of the blood in the laboratory dish.
Slukvin work and his team can be the first step in a new understanding of the cascade of events leading to blood disorders such as leukemia.
‘This is the first successful reprogramming of blood cells taken from a patient with leukemia,’ said University of Wisconsin-Madison stem cell researcher Igor Slukvin, who conducted a study to generate any stem cells using bone marrow and umbilical cord blood. ‘We were able to transform the cells into pluripotent stem cells sick. This is important because it provides a new model for the study of cells.’
The new work could open up the vast repository of tissue elevated science, health and disease, such as bone marrow, the soft tissue in the bones, which contributes to the blood and umbilical cord blood. The work may be behind the penetrating models can expose the cellular events that go wrong and cause cancers such as leukemia and could facilitate the development of new therapies based on stem cells, according Slukvin.
The research was reported in the journal Blood and colleagues from the WiCell Research Slukvin Institute and the Morgridge Institute for research, private research centers in Madison.
Slukvin group, using a bank of healthy and diseased bone marrow and umbilical cord blood, used a technique developed in 2009 by pioneer James Thomson of Wisconsin stem cells, which avoids the problems of the genes and viral vectors used to induce mature cells to regress to a state of stem cells.
In the new study, which was funded by the National Institutes of Health and The Charlotte Geyer Foundation, the reprogramming of cells to become blood stem cells induced is many times more effective than reprogramming of skin cells, mature cells that were first to be led to a new type of stem cells in its infancy.
‘This is very important for developing new drugs leukemia,’ says Slukvin. ‘One of the main objectives of leukemia research is to find ways to try to eliminate the leukemia cells more immature stem cells cancer -.’
‘When using viruses (for carrying genes into a cell) is the chromosomal integration,’ notes the researcher of Wisconsin. ‘Some of the factors and oncogenes for reprogramming to undermine the study of chronic myeloid leukemia’, which are encoded on chromosome abnormalities.
The reprogramming technique developed by Thomson and his colleagues, Slukvin said, is important because it eliminates the reprogramming genes exotic, including some genes linked to cancer, stem cells induced by the equation. In the case of chronic myeloid leukemia and other blood disorders, the derivation of stem cells that have the genetic reprogramming is very important.
In addition to Slukvin, a researcher at the Wisconsin National Primate Research Center (WNPRC) and associate professor of pathology at UW-Madison School of Medicine and Public Health, the authors of the new study include Kejin Hu Chung-ying Yu and Choi Kyung-Dal WNPRC; Kran Suknuntha the UW-Madison School of Medicine and Public Health; Shulan Tian, Ron Stewart and James A. Thomson, the Morgridge Institute for Research and WiCell Research Institute of Karen Montgomery.
