The tell-tale heart: Firefly genes for stem cell tracking

As mentioned in a previous post, in order to fully understand what’s happening when stem cells are used for in clinical or in vivo research, we need some way to track them, preferably in a non-invasive manner. This can be done with either reporter genes or some...

RNA-induction: A new method for iPS cell production

The reprogramming of differentiated adult cells into induced pluripotent stem (iPS) cells is accomplished by the expression of a small number of key genes. This is typically done by introducing DNA either by transfection or with viral vectors. Current methods,...

Special delivery: Getting stem cells into the spinal cord

Day two of the World Stem Cell Summit featured a much-anticipated update on a groundbreaking clinical trial launched in January to assess the safety and feasibility of injecting fetal stem cells into the spinal cords of people with Amyotrophic Lateral Sclerosis (ALS)....

Fireside chat with Jim Till and Janet Rossant

What happens when two great scientists sit down for a one-on-one to talk about their work, their mentors and what motivates them? Yes, you get some great chemistry, but more than that, you get a fascinating look at the people and process behind the identification of...
