• Resumen

  • Reports on the attempt by Stanford University scientists to recreate the niche where stem cells normally dwell in an effort to determine how and what signals the stem cell receives which determine its nature. Description of the microscopic labs measured in nanometers on a silicon chip and how the scientists will send chemical messages to the stem cells; How the scientists hope to grow tissue layer by layer and composite tissue which naturally bonds with the body's; Comments from Stanford materials scientist Nicholas A. Melosh; Scientists' concerns about the niche seals and electric current used to unseal them. INSET: PROBLEM OF PUSH AND PULL.
