Facial defects shown to self-repair
Date:4/25/2012

MEDFORD/SOMERVILLE, Mass. (April 25, 2012) Developmental biologists at Tufts University have identified a "self-correcting" mechanism by which developing organisms recognize and repair head and facial abnormalities. This is the first time that such a mechanism has been reported for the face and the first time that this kind of flexible, corrective process has been rigorously analyzed through mathematical modeling.

The research, reported in the May 2012 issue of the journal Developmental Dynamics, used a tadpole model to show that developing organisms are not genetically "hard-wired" with a set of pre-determined cell movements that result in normal facial features. Instead, the process of development is more adaptive and robust. Cell groups are able to measure their shape and position relative to other organs and perform the movements and remodeling needed to compensate for significant patterning abnormalities, the study shows.

"A big question has always been, how do complex shapes like the face or the whole embryo put themselves together? We have found that when we created defects in the face experimentally, facial structures move around in various ways and mostly end up in their correct positions," said Michael Levin, Ph.D., senior author on the paper and director of the Center for Regenerative and Developmental Biology in Tufts University's School of Arts and Sciences. "This suggests that what the genome encodes ultimately is a set of dynamic, flexible behaviors by which the cells are able to make adjustments to build specific complex structures. If we could learn how to bioengineer systems that reliably self-assembled and repaired deviations from the desired target shape, regenerative medicine, robotics, and even space exploration would be transformed."

Previous research had found self-correcting mechanisms in other embryonic processes though never in the face but such mechanisms had not been mathematically a
