2:17 PM | The Attraction of Axons; the Moth or the Spider?
An axon is attracted towards its target by guidance cues.  A moth flies towards the source of a pheromone.  A spider is sucked across the floor towards the nozzle of a vacuum cleaner.  Is the attraction of an axon towards its target more like the movement of the moth or the spider?credit: pmillera4External molecules direct the movement of the axon, the moth, and the spider.  In response to pheromone molecules a moth directs its movement toward the source of the […]

10:57 AM | What do you call your PCR machine?
Last Friday we came across the blog of the Sauka-Spengler lab in Oxford, and noticed that their PCR machines are called Kit and Kat. This made us think- who else gives pet names to their lab equipment? We asked the twittersphere for suggestions, and collated them in the storify below. How about your lab? Share […]

2:48 PM | Flies with colon cancer help to unravel the genetic keys to disease in humans
Researchers generate for the first time Drosophila melanogaster with intestinal cancer and reveal key genetic factors behind human colon cancer. The scientists identify a human gene that favours the proliferation of tumour cells in early stages of colon cancer. Furthermore, the flies are useful for faster and more economic drug screening. Researchers at the Institute […]

11:43 AM | Crossing fields- EMBO conference on interdisciplinary plant development
There is something exciting about biologists joining forces with physicists and/or mathematicians, and finding a common language to solve biological problems that are just too complex to understand without stepping outside the realm of ‘traditional’ biology. At the recent EMBO conference on plant development, interdisciplinary studies were the main focus. And as the organiser of […]

Here are the highlights from the current issue of Development:   Small (molecule) steps to making bone The repair of cartilage and bone following damage remains a clinical challenge. Current cell-based therapies rely mostly on adult mesenchymal stromal cells, but the expansion of these into correctly differentiated and functionally competent chondrocytes, which give rise to […]

10:46 PM | Tough decisions for the developing brain
To form complex organs, somatic stem cells proliferate and then differentiate during development. In this process, intrinsic factors, i.e. the sequential expression of transcriptional genes, and extrinsic factors, i.e. extracellular microenvironment, are intimately involved. Recent in vitro studies have revealed that the physical properties of the extracellular niche, possibly tissue stiffness, may play an important […]

10:37 AM | What do sperm have to do with brain tumors?
  This post was originally published in the Knoepfler Lab Stem Cell Blog.      Sometimes in science there are unexpected threads tying seemingly very different things together. Unraveling the knots in these threads can lead to new insights into important developmental processes and mechanisms of disease. My lab studies epigenomic and transcription factors including […]
