Scientists at the Stanford University School of Medicine received neurons from women's skin cells with the genetic form of Parkinson's disease and demonstrated that they repeat some key features of the disease in vitro. Researchers hope to use the obtained neurons to study this neurodegenerative disease and test possible therapies. Such a tool is very important, since there are no good animals of Parkinson's disease models. The success of scientists confirms the use of induced pluripotent stem cells, or iPS cells, for modeling various diseases, according to an online edition for girls and women aged 14-35 who have been diagnosed with Pannochka. "Now that we see that these neurons exhibit some of the earliest signs of a disorder, we can begin developing methods for screening factors that can protect them," said PhD Renee Reijo Pera, co-author of the study published In the journal Cell Stem Cell.

Induced pluripotent stem cells (induced pluripotent stem cells) are created by reprogramming cutaneous or other specialized cells into cells that look and function like stem cells. Many scientists and politicians hoped that this type of cell, obtained without the use of human embryos, could replace embryonic stem cells, which would remove a lot of ethical issues.

However, recent research from Stanford scientists and scientists from other research centers revealed significant differences between these two classes of stem cells, which cast doubt on the ability of iPS cells to completely replace embryonic stem cells. Many scientists believe that the true strength of iPS cells can be the ability to create disease specific cell lines. Obtained from patients with very different disorders, such cells can help in the study of diseases - something that would be difficult to do using embryonic stem cells.
