• Improving the development of new cancer models using advanced biomedical imaging method

  Scientists at the University of Arizona Cancer Center and the Moffitt Cancer Center, led by Dr. Robert Gillies, have demonstrated that an advanced magnetic resonance imaging (MRI) method can non-invasively evaluate the cellular proliferation of tumor models of breast cancer. This quantitative imaging method evaluates the diffusion of water in [...]

• New study exposes living cells to synthetic protein

  One approach to understanding components in living organisms is to attempt to create them artificially, using principles of chemistry, engineering and genetics. A suite of powerful techniques—collectively referred to as synthetic biology—have been used to produce self-replicating molecules, artificial pathways in living systems and organisms bearing synthetic genomes.

  In a new [...]

• Steering Stem Cells to Become Two Different Tissues for New Blood Vessels

  Growing new blood vessels in the lab is a tough challenge, but a Johns Hopkins engineering team has solved a major stumbling block: how to prod stem cells to become two different types of tissue that are needed to build tiny networks of veins and arteries.

  The team’s solution is reported [...]

• Cellular Patterns of Development

  For a tiny embryo to grow into an entire fruit fly, mouse or human, the correct genes in each cell must turn on and off in precisely the right sequence. This intricate molecular dance produces the many parts of the whole creature, from muscles and skin to nerves and blood.

  So [...]
