Stem Cells Cycle their Way towards DifferentiationAugust 31, 2015Genes that code for some developmental regulators in embryonic stem cells (ESCs) might be excused if they seem a little confused. The regulatory signals they receive from their enveloping histone environment are a combination of “Stop!” and “Go!” signals for their transcription. Although this seems counterintuitive, this combination of modifications, known as a bivalent domain, […]
UBER: Cross-Species, Drag-and-Drop Gene CircuitsAugust 26, 2015There’s a bit of a dirty little secret in synthetic biology – gene circuits that work great in one species often require a lot of changes to work in anything else. This is one reason so many synbio papers contain the same two key words: E. and coli. Now, a new approach called UBER (Universal […]
RiboT: Synthetic Ribosome Opens Door to Independent Genetic CodesAugust 25, 2015Synthetic biologists have made a lot of progress in developing “orthogonal” genetic systems. DNA and RNA have been made with synthetic base pairs, and cells have been coaxed to produce proteins with synthetic amino acids. This expands the genetic code beyond the standard letters used by life on Earth, which could potentially open up new […]
ChIPmentation: The Next Fast and Low-Input ChIP-seq SensationAugust 25, 2015ChIP-Seq is the bread and butter of histone and transcription factor research. It has seen countless modifications to allow it to perform under all the variables biology can throw at it, but with that specialization has come limitations to generalization. Now the methodological maestros in the lab of Christoph Bock, which brought us single-cell methylome sequencing, […]
Two Cocktails to Boost Reprogramming to NeuronsAugust 17, 2015Trendy drinks come and go, but it looks like there are a couple of new cocktails that will have some staying power within the stem cell community. In last week’s issue of Cell Stem Cell, two independent groups report in back-to-back papers the development of small molecule chemical cocktails, which enable neurons to be directly derived […]
