A detailed view of mice and fish Michael Wong wrote about the 3D mouse embryo atlas he has worked on. The high-resolution atlas of an E15.5 mouse embryo allows for easier phenotyping of mutant strains, which can then be compared to the wildtype. “If you have two groups of mouse embryos, one wild-type and one[…]

This rather lengthy summary describes a fascinating progress in the field of GRN modeling; it is a review of the article “Predictive computation of genomic logic processing functions in embryonic development”, which appeared few days ago in PNAS. Gene regulatory networks (GRNs) are complex systems of interacting genes that deploy in both space and time[…]

The Wellcome Trust-Medical Research Council Stem Cell Institute provides outstanding scientists with the opportunity to undertake ground-breaking research into the fundamental properties of mammalian stem cells. The Institute offers a comprehensive flow cytometry service to its members. The facility comprises MoFlo and FACSAria l cell sorters, Cyan and LSR-Fortessa analysers, and associated flow cytometry equipment.[…]

The purpose of this summary is to present to “The Node” readers a recent update to the story which, in my opinion, is a quite interesting example of the phenomenon of programmed genome rearrangement (PGR) that occurs in the lamprey Petromyzon marinus. Programmed genome rearrangement describes the regulated structural changes in the genome, which result[…]

Here are the highlights from the current issue of Development: Retinoic acid’s developmental role illuminated The role of all-trans retinoic acid (RA) in hindbrain development and other developmental processes is usually studied by blocking endogenous RA synthesis and then continuously supplying exogenous RA by soaking embryos in all-trans RA or by implanting RA-soaked beads.[…]

Let’s take a very close look at the inside of a fish! A recent paper in the Journal of Cell Biology describes a technique for generating large, composite, images from electron microscopy data. Frank Faas, Raimond Ravelli, and colleagues at the Leiden University Medical Center developed a method to computationally collect and align EM images.[…]

A few months ago, we published an interview with Stephen Fleenor, who won the poster award at the BSDB meeting. He won attendance to the SDB meeting in Montreal, where he passed on the baton and interviewed the winner of the SDB poster prize, John Young: Stephen Fleenor: In which lab do you work? John[…]

I’ve just returned from this year’s Santa Cruz Developmental Biology meeting. Some of you may have seen the tweets I was sending out from there (see Storify for the collected set), but a combination of limited ability to multitask and limited laptop battery life meant I didn’t cover all the talks. So to add to[…]
