PROVIDENCE, R.I. [Brown University] — When it comes to growing cells in a lab, technique matters. A new Brown University study shows that nerve cells grown in three-dimensional cultures use 1,766 genes differently compared to nerve cells grown in standard two-dimensional petri dishes. The study, published in the May issue of Tissue Engineering, adds to a growing body of research showing that culture techniques can significantly affect cell growth and function. This research shows that cells grown in a laboratory in 3-D environments, not in flat petri dishes, are more like cells grown in the ultimate 3-D environment – the human body.
