Signal gradients in 3-D guide stem cell behavior

[unable to retrieve full-text content]Researchers have developed an easy and versatile way of forming physical and biochemical gradients in three dimensions -- a step toward identifying the recipes that induce stem cells to generate specific tissues, including multiple tissues, such as a bone-cartilage interface. Ultimately, one of their goals is to engineer systems to manipulate stem cells to repair or replace damaged tissues and organs.
