Automating Pluripotent Stem Cell Culture – The Rise of the Robots?December 4, 2015They help cook dinner, clean the dishes, and sweep up afterward. They also build our cars, help us explore space, and now they may be on the verge of aiding in highly complex tasks in the laboratory. In particular, robot-based automation is being explored as a means to enhance efficiency in laboratories studying pluripotent stem […]
Different Pluripotent Stem Cells Remain Functionally SimilarNovember 12, 2015Coke vs. Pepsi, Domino’s vs. Pizza Hut, Bud vs. Miller. Could you tell the difference them in a taste test, given that they are made in a slightly different way with slightly different starting materials? And in the end, if each option does the job they were designed to do (filling bellies!), will any slight […]
Linking RNA Modifications and Stem Cell PluripotencyNovember 12, 2015Recent studies reported here at Epigenie have identified N6-methyladenosine (m6A) as a highly dynamic RNA modification that influences all aspects of RNA biology. Furthermore, an interesting study in mouse and human embryonic stem cells (ESCs) has indicated a role for N6-methyladenosine in the switch between ESC pluripotency and differentiation. Cool stuff indeed, but whate regulates N6-methyladenosine deposition […]
Towards Bioprinting Organs with Human Stem CellsOctober 30, 2015Printing has come a long way since the days of Johannes Gutenberg and his famous press. Nowadays, we are printing plaster casts for broken bones, replacement parts for space stations and now, a new study shows us that we are well on our way to be able to print human organs. This version of printing, […]
Stem Cell Scientists Use Cell Reprogramming Techniques to Study AgingOctober 22, 2015“Work harder, eat less, and, I’m begging you, get a haircut!” A face-to-face meeting between a younger and an older version of yourself would surely be filled with sage advice on how to live life and grow old gracefully. Many scientists wish to recreate such a meeting between young and old neurons to study aging and […]
Stem Cell-Derived Kidney Organoids Take a Big Step ForwardOctober 22, 2015Much like finding water on Mars and the fight to be the next President of the USA, pluripotent stem cell-derived mini-organs (or organoids) are big news at the moment. A recent study, featured here at EpiGenie, used a brain organoid generated from patient-specific induced pluripotent stem cells (iPSCs) to unravel the molecular causes behind autism. […]
Key Factors that Mend Broken HeartsSeptember 30, 2015Jimmy Ruffin once asked, “What becomes of the broken hearted?” and the answer is normally found on a barstool or at the bottom of an ice cream tub. But for those suffering from the much more visceral consequences of a heart attack, the therapeutic avenues down which they can travel are more limited and less […]
Sorting the Old from the New – Cellular Barriers Keeps Stem Cells YoungSeptember 29, 2015Alongside smartphones, coffee shops, and bars, we all also need properly functioning stem cells to survive and prosper. Indeed, the stem cell theory of aging posits that the malfunctioning of stem cells in our later years, and not all that caffeine and alcohol, is the major cause of human aging. So how do we keep […]
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, […]
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 […]
