‘miR-290 Cluster Modulates Pluripotency by Repressing Canonical NF-ĸB Signaling’

MicroRNAs (miRNA) have emerged as central players in regulating multiple aspects of cellular function, including the induction and control of pluripotency....

HIF-2α Suppresses p53 to Enhance the Stemness and Regenerative Potential of Human Embryonic Stem Cells

Tissue stem cells are understood to contribute to the repair and regeneration of the inflamed and damaged tissues through the secretion of growth factors and antioxidants (Prockop 2009) which they express at high levels...

DNA Hypermethylation in Somatic Cells Correlates with Higher Reprogramming Efficiency

Widespread epigenetic remodelling is acknowledged as being a critical process in the reprogramming of somatic cells to induced pluripotent stem cells (iPSCs), and the incomplete erasure of the epigenetic signature of somatic cells (“...

A Comparative Transcriptomic Analysis Reveals Conserved Features of Stem Cell Pluripotency in Planarians and Mammals

Planarians are free-living freshwater flatworms well-known for their extreme regenerative abilities linked to the existence of a large population of pluripotent adult stem cells (ASCs) (Wagner et al...

miRNAs Regulate p21Waf1-Cip1 Protein Expression and the DNA Damage Response in hESCs

p53-p21-mediated regulation of the G1/S checkpoint pathway of the human cell cycle is a vital control point of proliferation, and the molecular pathways governing the G1/S transition are also known to play a key role in the DNA damage...

Targeting RSK Eliminates Tumor-Initiating Cells by Inactivating YB-1 in Triple-Negative Breast Cancers

Triple-negative breast cancer (TNBC) refers to any breast cancer that does not express the genes for estrogen receptor (ER), progesterone receptor (PR) or Her2/neu andtherefore does not respond to conventional...

Dual Inhibition of Src and GSK3 Maintains mESCs, Whose Differentiation Is Mechanically Regulated by Src Signaling

Much is known about the effects of soluble factors and how they impact signalling pathways to control the basic biology of embryonic stem cells (ESCs).   Recent studies have revealed that the mechanical...

July 16, 2012 | Haploid Stem Cells

Haploid stem cells allow functional screening for genes involved in diverse cellular and developmental processes, and have the potential to be used in place of gametes to create animal models (Kaufman et al and Yan et al). However, mouse embryonic stem cells (ESCs) originally established from haploid embryos display a diploid karyotype (Kaufman et al), but recent studies have...

July 16, 2012 | Pluripotent Stem Cells

Embryonic stem cells (ESCs) maintained in serum are often morphologically heterogeneous and also express pluripotency associated transcription factors in a heterogeneous manner (Toyooka et al) perhaps suggesting that the pluripotent state in unstable. However, the derivation and maintenance of mESCs in serum-free conditions through the use of two small molecule kinase (Mek and GSK3)...

July 16, 2012 | Embryo Development

DNA methylation during mouse development is known to be a dynamic process; fertilization involves the removal of paternally contributed DNA, and this loss of DNA methylation continues until the blastocyst stage, when the inner cell mass (ICM) forms (Reik et al). After this stage, embryo implantation occurs alongside global re-methylation of the genome that is believed to contribute to...
