Along with his team, he used glass balls with distances across going from 5 microns to 4 millimeters. They found that the base distance across of a glass ball on which a human mesenchymal undifferentiated cell can connect and spread is 500 microns. Their experiments uncovered that the human mesenchymal stem cell developing on the glass balls with distances across of 1.1 millimeters and underneath were separating into fat cells without the expansion of any separation acceptance media. This implies surface bends of a substrate could conceivably be outlined and improved to accomplish or change a particular cell shape and capacity.
