Novel Adult-Onset Systolic Cardiomyopathy Due to MYH7 E848G Mutation in Patient-Derived Induced Pluripotent Stem Cells

Patient-specific induced-pluripotent stem cells-derived cardiomyocytes recapitulate the pathogenic phenotypes of dilated cardiomyopathy due to a novel DES mutation identified by whole exome sequencing.

In this paper, we report a novel heterozygous mutation of A285V codon conversion on exon 4 of the desmin (DES), using whole exome sequencing (WES) in an isolated proband with documented dilated cardiomyopathy (DCM). This mutation is predicted to cause three-dimensional structure changes of DES. Immunohistological and electron microscopy studies demonstrated diffuse abnormal DES aggregations in ...

Induced Pluripotent Stem Cells: Challenges and Opportunities

Regenerative capacity of mammals is limited and can rarely regenerate a specific organ or tissue fully. Due to these limitations, regenerative medicine seeks efficient and safe cell sources for regeneration of damaged tissues and organs or treatment for incurable diseases. Human embryonic stem cells (HESCs) hold two important properties called self renewal and pluripotency. However, the use of ...

Modeling neurological diseases using patient-derived induced pluripotent stem cells.

Reprogramming of somatic cells to an embryonic-like state has dramatically changed the landscape of stem cell research. Although still in its formative stages, the field of induced pluripotent stem cells (iPSCs) has the potential to advance the study of neurodegenerative and neurodevelopmental disorders at the molecular and cellular levels. The iPSC technology could be employed to establish in ...

Human Testis–Derived Pluripotent Cells and Induced Pluripotent Stem Cells

Alpha-Tocopherol increases the proliferation of induced pluripotent stem cell derived neural progenitor cells

In addition to its antioxidant effect, Vitamin E or α–tocopherol is suggested to enhance remyelination in the animal model of non-inflammatory demyelination. In this study, the possible proliferative effect of vitamin E on human- induced pluripotent stem cell-derived neural progenitors (hiPS-NPs) and the underlying mechanisms were investigated in vitro. NPs were induced from iPS cells via 3 ste...
