Engineers at Delft University of Technology have discovered that living cells can respond differently to the geometries of biomaterials around them. This could be used as an important step in repairing damaged tissues instead of using drugs, the university writes in a press release.<\/a><\/p>\n\n\n\n

Cells respond to geometry of surfaces<\/strong><\/h2>\n\n\n\n

Amir Zadpoor, professor of Biomaterials and Tissue Biomechanic, explains that “cells sense and respond to the geometry of surfaces they are exposed to.”<\/p>\n\n\n\n

Lidy Fratila-Apachitei adds that “Cells prefer a saddle shape – if they perceive one nearby, growth is stimulated.” The study shows that cells prefer valleys over hills. Cells collectively align their stress fibers with curvatures experienced in order minimize bending.<\/p>\n\n\n\n

In petri dishes, the researchers grew bone cells surrounded by small moulds made from biomaterials. Depending on the curvatures in the moulds, the cells tended to grow, divide, and form tissue to different extents. This research could be an important step in research into repairing damaged tissues.<\/p>\n\n\n\n
