Chromatin structure of pluripotent stem cells and induced pluripotent stem cells [PDF]

Briefings in Functional Genomics, 2011
Pluripotent embryonic stem (ES) cells are specialized cells with a dynamic chromatin structure, which is intimately connected with their pluripotency and physiology. In recent years somatic cells have been reprogrammed to a pluripotent state through over-expression of a defined set of transcription factors.

An introduction to induced pluripotent stem cells [PDF]

British Journal of Haematology, 2010
SummaryRecent landmark studies show that it is now possible to convert somatic cells, such as skin fibroblasts and B lymphocytes, into pluripotent stem cells that closely resemble embryonic stem cells. These induced pluripotent stem (iPS) cells can be generated without using human embryos or oocytes, thus bypassing some of the ethical issues that have ...

Pluripotency of Induced Pluripotent Stem Cells

Genomics, Proteomics & Bioinformatics, 2013
Abstract Induced pluripotent stem (iPS) cells can be generated by forced expression of four pluripotency factors in somatic cells. This has received much attention in recent years since it may offer us a promising donor cell source for cell transplantation therapy. There has been great progress in iPS cell research in the past few years.

Cryopreservation of Induced Pluripotent Stem Cells [PDF]

Cell Medicine, 2012
Induced pluripotent stem (iPS) cells have attracted attention as a promising cell source for medical treatment that could replace marrow stromal cells (MSCs) and adipose tissue-derived stem cells (ASCs). These pluripotent cells can be induced in vitro and in vivo to differentiate into various tissues and organs.

A novel -mutated human induced pluripotent stem cell model for understanding -mutated tumors

Tumor Biology, 2020
A missense mutation of the guanine nucleotide binding protein alpha stimulating activity polypeptide 1 ( GNAS ) gene, typically Arg201Cys or Arg201His (R201H/R201C), leads to constitutive activation of the Gsα-cyclic AMP (cAMP) signaling pathway that ...

Erythroid differentiation of human induced pluripotent stem cells is independent of donor cell type of origin

Haematologica, 2015
Epigenetic memory in induced pluripotent stem cells, which is related to the somatic cell type of origin of the stem cells, might lead to variations in the differentiation capacities of the pluripotent stem cells.

Absence of Rybp Compromises Neural Differentiation of Embryonic Stem Cells

Stem Cells International, 2016
Rybp (Ring1 and Yy1 Binding Protein) is a transcriptional regulator and member of the noncanonical polycomb repressive complex 1 with essential role in early embryonic development.

Two sides of the same coin? Unraveling subtle differences between human embryonic and induced pluripotent stem cells by Raman spectroscopy

Stem Cell Research & Therapy, 2017
Background Human pluripotent stem cells, including embryonic stem cells and induced pluripotent stem cells, hold enormous promise for many biomedical applications, such as regenerative medicine, drug testing, and disease modeling.

Induced Pluripotent Stem Cells at Nanoscale [PDF]

Stem Cells and Development, 2009
Reprogramming of mouse and human somatic cells into induced pluripotent stem (iPS) cells has been made possible with the expression of the transcription factor quartet Oct4, Sox2, c-Myc, and Klf4. Here, we compared iPS cells derived from mouse embryonic fibroblasts with the 4 factors to embryonic stem cells by electron microscopy.

Histone deacetylase inhibitor valproic acid promotes the differentiation of human induced pluripotent stem cells into hepatocyte-like cells. [PDF]

PLoS ONE, 2014
In this study, we aimed to elucidate the effects and mechanism of action of valproic acid on hepatic differentiation from human induced pluripotent stem cell-derived hepatic progenitor cells.
