Small Molecule Cocktails are a Big Hit at the Cellular Reprogramming PartyMay 6, 2016Cellular reprogramming represents the biological equivalent of spinning gold from straw: the generation of one therapeutically-desired cell type from another more abundant, and less useful, starting cell type. Following reprogramming, we can incorporate the resultant cells into new and effective patient-specific regenerative strategies. Reprogramming of somatic cells into induced pluripotent stem cells (iPSCs) generates a […]
iPSC Generation Gets a “Little” Help from MicrofluidicsApril 29, 2016Long complex steps, poor efficiency, expensive reagents, and scant results…don’t you wish that your cell-based experiments were a “little” bit easier and a “little” more efficient? These desires are commonplace for researchers generating induced pluripotent stem cells (iPSCs) in the hope of constructing patient-specific therapies. So what can we do to improve this important process? […]
“There is another” – N6-mA Described as a New Form of DNA MethylationApril 9, 2016In one of modern cinema’s greatest movies, Jedi Master Yoda proclaims “No…there is another…”. He was talking about the presumed existence of only one Jedi, much as many mammalian biologists speak about 5-methylcytosine (5-mC) as being the only type of DNA methylation. In a ground breaking new study, Andrew Z. Xiao (Yale School of Medicine, […]
Redefining Cancer and Stem Cell Reprogramming: Epigenetic Modulators, Modifiers, and MediatorsApril 9, 2016Back in 2006, Andrew Feinberg & Co. brought forth a review that pioneered the concept of tumor progenitor genes, which are genes involved in stem cell reprogramming and cancer. These tumor progenitor genes are epigenetically deregulated at the earliest stage of cancer. The epigenetic variation occurs before mutations, can be seen in normal tissue surrounding […]
Zika Virus Infection of Neural Progenitors Linked to Brain AbnormalitiesApril 1, 2016The sight of newborn infants with radically reduced brain sizes (microcephaly) has seized attention worldwide and thrust the Zika virus into the limelight as the probable culprit. Zika spreads through mosquito bites and belongs to the Flaviviridae virus family, but how does Zika infection cause such devastating abnormalities in developing infants? A multidisciplinary team led […]
Human Haploid ESCs – Half the DNA but Double the Potential?April 1, 2016Eyes, feet, hands, and chromosomes – two of each seems to be the done thing. Indeed, two sets of each chromosome (diploidy) is a general feature in mammals, except when we produce eggs and sperm (meiosis) which contain only one set of chromosomes (haploidy). However, various studies have described the production of embryonic stem cells […]
DNA Methylation and Transcription Data from Single Stem CellsJanuary 28, 2016Ever wanted to be able to do two things at the same time? Like work and have a social life? Eat pizza and still fit in your new purchases? Pat your head and rub your belly? While these highly important combinations remain almost impossible (at least for the EpiGenie staff), a stellar cast of scientists […]
CRISPR Gene Editing Prefers the Naïve Side of PluripotencyJanuary 11, 2016While many across the universe have been pondering over the decision between the light and the dark side of the Force, a more pressing decision confronts CRISPR-based gene editing in stem cells: the primed or the naïve side of pluripotency!? Pluripotent Stem Cells (PSCs), such as human induced pluripotent stem cells (hiPSCs), human embryonic stem […]
Human Pluripotent Stem Cells (hPSCs) Elevate Performance with Chimera FormationJanuary 8, 2016Ask Usain Bolt, Yelena Isinbayeva, or Lindsey Vonn and they will tell you that Gold is the only thing that matters. To them, it came in the guise of an Olympic medal (or two), but human pluripotent stem cells (hPSCs) have been in the hunt for a slightly different type of gold to prove their […]
Going Direct: Reprogramming without iPSCs in Cell TherapiesDecember 21, 2015The generation of induced pluripotent stem cells (iPSCs) represents one of the most important scientific breakthroughs of our times, bringing us to the brink of patient-specific stem cell-based therapies. The “simple” generation process involves the forced expression of transcription factor genes in differentiated cells taken from the patient (normally skin cells) to “kick-start” the pluripotency-associated […]
