Abstract:
A novel OCT4 alternative spliced variant (OCT 4B1) is deduced to be the isoform present in 59 hESC lines characterised by the International Stem Cell Initiative (ISCI) rather than OCT4A as previously assumed. The new variant may be a more reliable marker of stemness than OCT4A and studies are needed to test this.

Chromatin Modification in iPS Cells
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...
