Drs. Chia Soo and Bruno Péault, from the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, have found a way to turn stem cells from fat tissue into bone of higher quality than that grown with prior techniques. The mesenchymal stem cells (MSCs) isolated from the fat tissue may develop into bone, cartilage, muscle as well as other tissues. More importantly, fat tissue is easily accessible through liposuction. What is unique about their research is that they were able to purify stem cells from fat tissue relatively quickly. Until now, the isolated cells were a…
On Discovering Biology in a Digital World, Sandra Porter imagines the fallout of HR 3699, a bill that would eliminate the requirement for free public access to NIH-funded research papers. Porter writes, "The reasoning behind this requirement is that taxpayers funded everything about the research except for the final publication, and so they have already paid for access." In small schools and community colleges without costly journal subscriptions, passage of this bill would effectively remove contemporary scientific literature from the classroom. Porter continues, "working in science, and…
