Gene Expression is affected when cells are cultured in petri dish

Posted Sep 12 2008 9:36am

When trying to figure out how different respond to drugs and other environemnts in the body scientists turn to cells. The cultured cells are grown in petri dishes now with the onset of tissue microarrays the process is getting more advanced

A new Brown University study shows that nerve cells grown in three-dimensional cultures use 1,766 genes differently compared to cells grown in standard two-dimensional petri dishes.

The research shows that culture techniques can significantly affect cell growth and function. cells grown in a laboratory in 3-D environments are more like cells grown in the ultimate 3-D environment - the human body.

“More and more, we’re seeing evidence that cells cultured in three dimensions look and behave more like cells in your body,” said Diane Hoffman-Kim, the University of Brown bioengineer who spearheaded the new study,

The study is published in the May edition of Tissue Engineering,
