A new tool developed by scientists at The Methodist Hospital separates tumor-causing cancer cells from more benign cells by subjecting the cells to a microscopic game of Plinko—except only the squishiest cells make it through. As reported in this week's Proceedings of the National Academy of Sciences (early edition online), the more flexible, tumor-causing cells navigated a gamut of tiny barriers, whereas the more rigid, more benign cells had trouble squeezing through 7 micrometer holes. Methodist scientists worked with University of Texas MD Anderson Cancer Center researchers to test the device with different kinds of cancer cells.
