Engineering stem cells Before scientists and engineers can realize the dream of using stem cells to create replacements for worn out organs and battle damaged body parts, they'll have to develop ways to grow complex three-dimensional structures in large volumes and at costs that won't bankrupt health care systems. Researchers are now reporting advances in these areas by using gelatin-based microparticles to deliver growth factors to specific areas of embryoid bodies, aggregates of...

New research findings show that embryonic stem cells unable to fully compact the DNA inside them cannot complete their primary task: differentiation into specific cell types that give rise to the various types of tissues and structures in the body. Researchers from the Georgia Institute of Technology and Emory University found that chromatin compaction is required for proper embryonic stem cell differentiation to occur. Chromatin, which is composed of histone proteins and DNA, packages DNA...

Stem cell technologies have been proposed for cell-based diagnostics and regenerative medicine therapies. However, being able to make stem cells efficiently develop into a desired cell type -- such as muscle, skin, blood vessels, bone or neurons -- limits the clinical potential of these technologies. New research presented on June 16, 2011 at the annual meeting of the International Society for Stem Cell Research (ISSCR) shows that systematically controlling the local and global environments...


Word of the Day

  • Having so marked an appearance as easily to be recognized.
This word may come from the Swedish 'kanspak,' quick at recognizing persons or things, or else from confusion with 'conspicuous.'
