MacArthur Foundation Grants: Lisa Griffith

September 21st, 2006 Tim Odell Medicine

Catherine Griffith, MacArthur FellowThis week the John D and Catherine T MacArthur Foundation (whose tag line is burned into the auditory cortex of any NPR listener) released the 25 names of their MacArthur Fellows for this year. Each recipient gets a “no strings attached” US$500k grant to further pursue their area of focus. Areas of focus range from sculpture and music to intense science and mathematics. More than a few fellows deserve Medgadget’s attention…
…And we’re starting with Lisa Griffith of MIT. She’s pursuing tissue engineering solutions for developing liver cells in vitro…

Griffith has designed several methods for fabricating scaffolds on which cultured cells can adhere and grow. An initial effort used linear polymer gels cross-linked by electron-beam radiation to form star-shaped structures. More recently, she developed a solid-phase method using L-lactic acid for precisely controlling the pore size and surface chemistry of three-dimensional substrates. Using this technique, she has explored the optimal conditions (e.g., pore size, growth media, cell density, fluid dynamics) necessary for liver cells to live and organize into physiologically functional units. With these results, Griffith is developing a powerful tool for exploring the normal function of the liver and the mechanisms of disease that attack it, offering the prospect of significant reduction in the need for future organ replacement or regeneration.

Tim Odell

Tim Odell started with Medgadget in 2005 while in graduate school at the University of Southern California. He prided himself on his irreverent tone and Pseudoscience Fridays series. After graduating in 2007, he began his career as a biomedical engineer with a Bioness, a neurorehabilitation start up, then moved on to Stryker in 2011.
