Retrotransposons in pluripotent stem cells [PDF]
Cell Regeneration, 2020 AbstractTransposable elements constitute about half of the mammalian genome, and can be divided into two classes: the class I (retrotransposons) and the class II (DNA transposons). A few hundred types of retrotransposons, which are dynamic and stage specific, have been annotated.

Pluripotency of induced pluripotent stem cells [PDF]
Journal of Animal Science and Biotechnology, 2012 Recent studies have demonstrated that differentiated somatic cells from various mammalian species can be reprogrammed into induced pluripotent stem (iPS) cells by the ectopic expression of four transcription factors that are highly expressed in embryonic stem (ES) cells.

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.

Induced pluripotent stem cells are induced pluripotent stem cell-like cells [PDF]
The Journal of Biomedical Research, 2015 Gold is rare and precious, while pyrite (FeS2) is abundant and cheap. Pyrite is nicknamed fool's gold, since pyrite looks like gold and it is even shinier and brighter than gold. It is very difficult to recognize the differences between a real natural gold and a gold-like rock (pyrite) to non-professional persons[1], but we know that all that glitters ...

The Role of E3s in Regulating Pluripotency of Embryonic Stem Cells and Induced Pluripotent Stem Cells [PDF]
International Journal of Molecular Sciences, 2021 Pluripotent embryonic stem cells (ESCs) are derived from early embryos and can differentiate into any type of cells in living organisms. Induced pluripotent stem cells (iPSCs) resemble ESCs, both of which serve as excellent sources to study early embryonic development and realize cell replacement therapies for age-related degenerative diseases and ...

Germline and Pluripotent Stem Cells [PDF]
Cold Spring Harbor Perspectives in Biology, 2015 Epigenetic mechanisms play an essential role in the germline and imprinting cycle. Germ cells show extensive epigenetic programming in preparation for the generation of the totipotent state, which in turn leads to the establishment of pluripotent cells in blastocysts.

Transfusion Clinique et Biologique, 2009 The isolation of human embryonic stem cells (ESC) in 1998 has created the hope that stem cells will one day be used to regenerate tissues and organs, even though it is obvious that a number of hurdles will need to be overcome for such therapies to become reality.

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.

miRNA in Pluripotent Stem Cells [PDF]
Regenerative Medicine, 2010 Embryonic stem cells and induced pluripotent stem cells are characterized by their ability to self-renew and differentiate into any cell type. The molecular mechanism behind this process is a complex interplay between the transcriptional factors with epigenetic regulators and signaling pathways.

Breathing Chromatin in Pluripotent Stem Cells [PDF]
Developmental Cell, 2006 Only a few factors controlling stem cell pluripotency have been identified to date, and we do not yet fully understand how they act to maintain pluripotency and control differentiation. A report in this issue of Developmental Cell (Meshorer et al., 2006) describes a new trait of pluripotent cells: hyperdynamic or "breathing" chromatin.
