X in Space (Now in 3D)

Posted by on June 20th, 2011

The 3D spatial arrangement of DNA within the nucleus is tightly controlled and has great functional significance. Each chromosome has been shown to occupy a defined nuclear territory and the expression of genes is often closely linked to where they are located, with similar expression levels seen for genes with similar locations. It has also[…]

Epithelial-to-Mesenchymal Transition meeting in Singapore (Oct.10-Oct.13)

Posted by on June 16th, 2011

The fifth international EMT (epithelial-to-mesenchymal transition) meeting will be held this year from Oct 10 to Oct 13 in the beautiful city state of Singapore.  The meeting is co-organized by Jean Paul Thiery and Erik Thompson. It will cover recent development in the EMT field, ranging from basic molecular and developmental mechanisms to translational research[…]

ISSCR meeting in Toronto – keeping up via Twitter

Posted by on June 15th, 2011

I’m currently in Toronto for the annual meeting of the International Society for Stem Cell Research (ISSCR), and you can expect to find updates about the meeting at various places. Of course we’ll cover it here on the Node itself, but we’re also using Twitter to share and follow news from the meeting. The ISSCR[…]

Visualizing stem cells at home

Posted by on June 13th, 2011

The Drosophila ovary is stunningly beautiful, and a playground of wonderful biological questions.  Within the germarium alone, developmental biologists can look at asymmetric division, stem cells and their niches, cell migration, and cell specification.  A recent paper in Development describes a technique allowing the in vitro imaging of a fruit fly ovary, and opens the[…]

Put your party hats on

Posted by on June 13th, 2011

If you take a look at our Facebook and Twitter pages today, you might notice that they look slightly different. Our regular logo is temporarily replaced with a special logo to celebrate our upcoming first birthday. That’s right – it’s been one year already! Our official birthday is on June 22nd, and if you check[…]

Embryonic development informs adult heart repair

Posted by on June 9th, 2011

After a heart attack, heart muscle is irreparably damaged, but a paper in Nature now reports that adult mouse hearts have a source of progenitor cells that can form new muscle cells after heart injury. A few years ago, studies showed that embryonic epicardial progenitor cells contribute to the cardiomyocyte lineage in developing mouse hearts.[…]

Round-up of alternative careers stories

Posted by on June 8th, 2011

In December we asked people to share how they moved from research to a career away from the lab bench. Since then, we’ve heard from a number of people, and a few stories are still coming in. Here’s the list so far, with current affiliations: Keep up and blog on – my route to the[…]

In Development this week (Vol. 138, Issue 13)

Posted by on June 7th, 2011

Here are the highlights from the current issue of Development: Mutant Xist merely muffles X chromosome In XX female mammals, inactivation of one X chromosome during development equalises the levels of X-linked gene products in females with those in males. Expression of the Xist gene from one of the two X chromosomes produces a non-coding[…]
