Whose life is it anyway? Building patient needs and goals into stem cell clinical trials

Author: Lisa Willemse, 12/21/11

In a traditional view of medical research, advances tend to be measured against the overarching goal of cure. Noble as this might be, research is rarely such a black and white affair — if we have learned anything, it’s that there are innumerable shades of grey. Even the goal itself can be questioned, especially when…Read more

17-year-old high school student makes a cancer stem cell breakthrough

Author: Stem Cell Network, 12/14/11

When we report on breakthroughs in stem cell research, we typically link to well-funded studies published in peer-reviewed journals by world-renowned scientists. This time, it’s a little different. Angela Zhang, a high school senior from Cupertino, California, was awarded a $100,000 scholarship for her submission to the 2011 Siemens Competition in Math, Science & Technology:…Read more

The apple of a bioengineer’s eye: mature photoreceptors

Author: Angela C. H. McDonald, 12/13/11

Last spring, I wrote about the remarkable generation of self-organizing retinal tissue created from mouse embryonic stem cells. The study successfully created all major retinal components including photoreceptors, albeit at a low abundance. However, while multi-layered optic tissue did form, the alignment and organization of mature retinal cell types differed from that of the mouse…Read more

Tick, tock, clock – the clock is ticking for you

Author: David Kent, 12/06/11

From the depths of the poetic frivolity of Raphael de la Ghetto come some words that might help guide us through one of the most interesting concepts being pursued by stem cell biologists these days.  Specifically, research has emerged which links stem cell behaviour and fate choices to circadian rhythm. The group of Salvador Aznar…Read more
