Penn Engineers: Cells Require Gene Expression Feedback to Keep Moving

By Lauren Salig

When cells move throughout the body, they do so by dragging themselves, using molecular “arms” to pull themselves closer to where they need to be while unlatching themselves from the area they’re moving away from. In a recent study, Penn Engineers looked at a few mechanobiological factors that help regulate cells’ migration towards their destination, providing new insight into the gene expression feedback loops that keep them from getting stuck.

The research was led by Joel Boerckel, Assistant Professor of Orthopaedic Surgery in the Perelman School of Medicine and in Bioengineering in Penn Engineering, and bioengineering graduate student Devon Mason. Co-authors include bioengineering graduate student Joseph Collins and researchers from the University of Notre Dame, Indiana University and Purdue University.

The study was published in the Journal of Cell Biology.
