dr. dolittle | June 12, 2012Drs. 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…

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…
