A new way of growing cancer cells in the lab developed at the University of Toronto Faculty Of Applied Science & Engineering could speed up the search for therapeutics.

"In highly invasive diseases, there is a crucial need to screen for both of these functions," says Shoichet. "We now have a way to do this."
Shoichet and her team are internationally known for their work on hydrogels, jello-like materials based on hyaluronic acid, a biocompatible substance commonly used in cosmetics. In the past, they have used hydrogels to enhance stem cells that are injected in the body to overcome disease or degeneration.
In their latest research, the team used hydrogels to mimic the environment of lung cancer, selectively allowing cancer cells, and not healthy cells, to invade.

This emulated environment enabled their collaborators in Professor Bill Stanford's lab at University of Ottawa to screen for both cancer-cell growth and invasion. The study, led by Roger Y. Tam, a research associate in Shochet's lab, was recently published in Advanced Materials.
"We can conduct this in a 384-well plate, which is no bigger than your hand. And with image-analysis software, we can automate this method to enable quick, targeted screenings for hundreds of potential cancer treatments," says Shoichet.

Using their hydrogels, they were able to automate and screen more than 800 drugs, thereby uncovering treatments that could target disease growth and invasion.

Shoichet, who was recently named a Distinguished Woman in Chemistry or Chemical Engineering, also plans to patent the hydrogel technology.
"This has, and continues to be, a great collaboration that is advancing knowledge at the intersection of engineering and biology," says Shoichet.
