May the Cellular Force Be With You: Otger Campàs measures the cellular forces that shape tissues and organs

Like tiny construction workers, cells sculpt embryonic tissues and organs in 3D space. This task is complicated and requires constant communication between cells to coordinate their actions and generate the forces that will shape their environment into complex tissue morphologies.

Biologists have long studied the communication between cells and their behavior while building these structures, but until now, it had not been possible to see the forces cells generate to shape them. A new method to quantify the mechanical forces that cells exert while building tissues and organs can help answer long unresolved questions in biology and provide new diagnostic tools for medicine.

Developed initially in the Wyss Institute at Harvard University by Otger Campàs and Donald Ingber, this technique is the first of its kind to measure the mechanical forces that cells generate in living embryos. Now an assistant professor who holds the Mellichamp Chair in Systems Biology at UC Santa Barbara, Campàs leads a lab that is developing this droplet technique in several new directions, and applying it to discover the patterns of cellular forces that shape embryonic structures in fish and chicken.
