Expectations of Epigenetic Research Studies Focusing on Mesenchymal Stem Cells

Epigenetic alternations are not associated with any changing the base sequence of DNA, but are closely related to phenome together with genome [1]. Most of them are determined differently under various external and internal influences and, even if abnormal, memorized over individual life. In the ontogeny that starts from a totipotent stem cell such as a fertilized egg, the epigenetic alternations occur in good order along with cell differentiation process toward peculiar epigenetic patterns of individual cell series. In contrast, a reverse artificial phenomenon induced by transduction of 4 genes, Oct3/4, Sox2, Klf4 and c-Myc (induced progenitor and stem cells: iPS cells) is known to accompany with significant abnormalities of DNA methylations, one of the epigenetic regulation mechanisms, fearing possible abnormal cell development. These cells should be used for elucidation of unknown reprogramming mechanisms rather than rough- and ready-clinical applications.

Ministernotomy Thymectomy in Mysthania Gravis-Future

Journal of Cardiovascular Medicine and Cardiology Research Article A thymectomy is the surgical removal of the thymus gland. The thymus has been demonstrated to play a role in the development of MG. It is removed in an effort to improve the weakness caused by MG, and to remove a thymoma if present.About 10% of MG patients have a tumor of the thymus called a thymoma. https://www.peertechz.com/articles/ministernotomy-thymectomy-in-mysthania-gravis-future.pdf
