Cancer cells give up their secret of protection; Stem cells cultured in 3-D;

Cancer

> Emory University scientists discovered that a gene known to prevent cancer development has another role: regulating tumor-induced angiogenesis, where growing cancers attract new blood vessels.  Release

> Scientists at the University of Zurich now know the cellular mechanism cancer cells use to protect themselves from damage. Story

Genetics

> Doctors in Utah are using a mathematical model, combined with patient genetic and health data, to customize doses of the blood thinner warfarin, The Salt Lake Tribune reports. Story

> Johns Hopkins-led researchers discovered 5 gene mutations they believe are connected to elevated blood platelet counts in African-Americans, a discovery that could lead to new drugs to prevent coronary artery disease. Release

Stem Cell Research

> University of Georgia scientists created a blueprint showing the way stem cells are wired to respond to external signaling molecules. This establishes a way to precisely control how stem cells grow or become different cell types. Release

> University of Victoria researchers can culture stem cells in 3-D in order to better monitor cell behavior as they grow and divide. Details are published in the Journal of Visualized Experiments. Release
