3-D scaffold provides clean, biodegradable structure for stem cell growth

February 2, 2010 | Source: Physorg.com

University of Washington researchers have built a three-dimensional scaffold out of a natural material, chitosan, that mimics the binding sites for stem cells and allowing the cells to reproduce on a clean, biodegradable structure.

Growing the cells in three dimensions better resembles conditions in the human body. It also allows for mass production, which will be needed for any clinical applications.
