Induced pluripotent stem cells (iPS cells) are truly talented multi taskers. They can reproduce almost all cell types and thus offer great hope in the fight against diseases like Alzheimer’s and Parkinson’s. However,

Mujeres Nike Free Run 3 azul de Tiffany Con Calida, it would appear that their use is not entirely without risk: during the reprogramming of body cells into iPS cells,

Nike Roshe Run Negro Rojo Malla Hombres Guardar Descuento Grande, disease causing mutations can creep into the genetic material. The genome of the mitochondria the cell’s protein factories is particularly vulnerable to such changes. This phenomenon has been discovered by researchers at the Max Planck Institute for Molecular Genetics in Berlin. The scientists encountered mutations in the mitochondrial genome of iPS cells. Because such genetic mutations can cause diseases,

Nike Roshe Run Hombres azul gris acolchado Nosotros Outlet Store, the cells should be tested for such mutations before being used for clinical applications.
A lot of hope is riding on induced pluripotent stem cells (iPS cells). Because they can be generated individually for every single person,
Nike Free Run 3.0 mujeres azules Nueva Colección Está Disponible, they are expected to enable the development of tailor made therapies that do not run the risk of triggering rejection reactions. iPS cells also offer a promising solution for drug screening,

The method raises no ethical concerns as it does not involve the destruction of embryos.
However,
Nike Roshe Run 2014 mujeres rojas Ant-piel Para Barato Pero El Real, these promising cells are also associated with certain risks. Disease causing mutations can also arise during the reprogramming of the body cells. The genetic material in the mitochondria is particularly vulnerable to changes in the genetic code. The question as to whether such mutations arise as a result of the reprogramming process had not previously been investigated.
A cooperative research study involving two research groups from the Max Planck Institute for Molecular Genetics in Berlin has now carried out a search for mutations in the mitochondrial genome of iPS cells. James Adjaye’s research group recently discovered that the mitochondria rejuvenate in the course of reprogramming. Working in cooperation with Bernd Timmermann’s Next Generation Sequencing research group,

Nike Free Run Powerlines Ii Negro Verde Mujeres Para Auténtico Barato, Adjaye’s team has succeeded in showing that genetic mutations exist in the mitochondrial genome of all reprogrammed cells that were not present in the original cells. The amount of mutations varies significantly between the individual iPS cells examined. In all cases,
2012 Nike Free Run 2 Blue donne di colore Abbiamo buona reputazione, the changes did not involve large scale rearrangements but rather modifications of single letters in the genetic code.
"The mitochondrial genome undergoes random reorganisation during reprogramming,
Nike Free Run 5.0 azul marino Gris Mujeres Precio Al Por Menor," explains James Adjaye. "Cell lines can arise in the process that carries disease causing mutations. Genetic mutations in the mitochondrial genome may be responsible,

One of the reasons why the mitochondrial genome is so vulnerable to mutations is that mitochondria do not have the ingenious molecular repair mechanisms found in the cell nucleus at their disposal. In addition,
