In Development this week (Vol. 142, Issue 13)

Posted by on June 30th, 2015

Here are the highlights from the current issue of Development:   Controlling Traffic jam for niche specification Tissue stem cells are dependent on their local microenvironment – the niche – for regulation of self-renewal and differentiation. In the Drosophila male germline, the niche comprises a set of 8-10 somatic cells called hub cells, which are[…]

Question of the month- societies

Posted by on June 30th, 2015

Last week the International Society for Stem Cell Biology meeting took place in Stockholm, and next week is the turn of the Society for Developmental Biology meeting, in Utah.  However, an annual meeting is not the only thing that a society may do. Other activities can include, for example, the publication of a peer-reviewed journal, advocacy for[…]

Scheduled Node maintenance- 1st of July

Posted by on June 29th, 2015

We will be doing some maintenance work on the Node this Wednesday the 1st of July, and unfortunately this means there will be no access to the site then. You can expect the Node to be down from 7 a.m. (British Summer time) for up to 4 hours. We are sorry for the disruption, especially for[…]

Nerves read the electrical topography of their microenvironment in making growth decisions

Posted by on June 29th, 2015

A really interesting recent paper on bioartificial limbs underscored the prospect of transplantation for problems in regenerative medicine. One key issue facing transplant technology is establishing appropriate innervation to the host. What factors control the amount of nerve emanating from an organ graft and the paths that this innervation takes? Alongside the familiar diffusible signaling[…]

Cellular Senescence in Regeneration

Posted by on June 28th, 2015

Salamanders are remarkable organisms. Following the amputation or loss of complex structures such as parts of their eyes, hearts and brains, tails -including the spinal cord-, jaws and even full limbs, they are able to set up a regeneration programme which leads to the exact replacement of the missing structure, even as adults. As such,[…]

Continuing the effort to bring young developmental biology researchers in the Boston area together, in a similar vein to the Young Embryologist Network in the UK, and following on from our previous[…]

Friendly hello and a bit about stress & adult hippocampal neurogenesis

Posted by on June 27th, 2015

This is my first post for the Node, so I thought I would introduce myself a little bit… I just finished my MSc in Experimental Psychology (Behavioural Neuroscience) and now I am striving towards becoming a science communicator. Although, I would like to share the research that I am interested in and was involved in,[…]

High school students blog about StemCellTalks

Posted by on June 27th, 2015

StemCellTalks is a Canadian high school outreach initiative that has been running in 7 Canadian cities since 2010. This symposium was established to facilitate knowledge transfer between academia and high school students pertaining to the science and practical ethics of stem cells. To date, over 500 graduate student and trainee volunteers have reached over 5000[…]
