This month on the Node – January 2013

Posted by on January 31st, 2013

Let’s start this monthly summary with two fantastic posts that were left out of last month’s roundup due to the holiday period (and scheduled posts). Idoia Quintana studies shark brain development in Spain, and travelled to Scotland recently to learn how to work with mouse brains, so she could do some cross-species comparison. “At the[…]

Post-doc position in evolution and development in Paris

Vote for a Development cover – Woods Hole 2012 class round 1

Posted by on January 30th, 2013

Each year, students of the Woods Hole Embryology course produce some amazing images. Last year, readers of the Node selected four images from the 2011 course to appear on the cover of Development.   Now it’s time to do the same with the images from the 2012 course. Here’s the first batch of four images.[…]

In Development this week (Vol. 140, Issue 4)

Posted by on January 29th, 2013

Here are the highlights from the current issue of Development:   Pancreatic injury unlocks cell potential Identifying methods by which pancreatic β-cells can be produced is of major therapeutic importance. Whether there are adult pancreatic cells with the potential to make new β-cells is a matter of much debate. During embryonic development, the transcription factor[…]

Stem cells at school, plus new fact sheets on EuroStemCell

Posted by on January 29th, 2013

Happy 2013 everyone! I hope you’re all settling into the year nicely.We sent out our EuroStemCell January newsletter last week and I thought some of you might be interested in our latest schools activities and fact sheets on stem cell research. Highlights this month include a new lesson for 12-14 year olds on Stem cell[…]

Woods Hole course application deadline extended

Posted by on January 28th, 2013

The Woods Hole image voting posts are some of the most popular posts on the Node (and yes, there will be a new one up VERY soon!). These images are all made by students of the Woods Hole Embryology course, and you still have a chance to be part of the 2013 class! The application[…]

Microinjection of preimplantation mouse embryos

Posted by on January 28th, 2013

Hello, my name is Stephanie and I’m a graduate student in Dr. Amy Ralston’s lab at the University of California Santa Cruz.  I just returned from a trip to Dr. Yojiro Yamanaka’s lab at McGill University in Montreal, Quebec.  This trip was funded by the Development Travelling Fellowship from Company of Biologists.  I highly recommend checking[…]

PhD opportunity available in Dundee

O-GlcNAc signalling during embryonic stem cell differentiation My lab is studying the signalling mechanisms governing the onset of differentiation of pluripotent embryonic stem (ES) cells. Work from this and other labs (e.g. 1, 2) has revealed a critical role for autocrine FGF signalling and consequent sustained phosphorylation of the kinase Erk during the differentiation process.[…]

PhD position in the UK for a Developmental Geneticist

Posted by on January 16th, 2013

PhD project title: Non-genetic mechanisms of inheritance influenced by the maternal environment Project description: In the last few decades, it has been becoming increasingly clear that organisms can express phenotypes that are inherited in a non-Mendelian fashion. Studies in humans, for example, show that grandfathers who experienced dramatic diet fluctuations as children influenced the incidence[…]

Early mouse development seen in real time

Posted by on January 15th, 2013

Developmental biologists have long relied on the power of observation to understand how embryos develop. In addition, pharmacologic and genetic manipulation of embryos gives us clues as to the mechanisms involved in proper developmental processes. The ability to combine embryo manipulation with observation of embryonic development in real time has been possible for quite some[…]
