Researchers create mathematical model of fruit fly eyes
Date:1/11/2008

branes and the energy of the glue (the adhesion molecules) that holds the neighboring cell membranes together. Hilgenfeldt took those two factors and created a quantitative model of cell geometries in the fruit fly retina. So instead of needing to know all the different cell factors to create the model, he just needed the two energy components to create the model.

Its one of the most quantitative models Ive seen for a biological system, Hilgenfeldt said. For this system, mainly all you need to know is the interfacial energies and everything falls into place.

Such a model helps researchers understand how the presence of the glue energy changes the shape of the eye and will help them study how those adhesion molecules develop and function during embryo development.

Further down the road, having these kinds of models could help scientists learn how to grow regenerative tissues. Hilgenfeldt also hopes to see how far he can take this model -- testing whether it will work in tissues that have much more variation in their cell patterns.

It is very promising for quantitative science to be able to do something about these complex biological systems, he said.

Though the undergraduate student who worked on the research has graduated, Hilgenfeldt said another undergraduate student will help continue the research through the Research Training Group (RTG) program in applied mathematics. The program emphasizes interdisciplinary research with teams composed of applied mathematicians, scientists and engineers. It is funded by a $2.1 million National Science Foundation grant.

This is precisely what the grant is supposed to do, Hilgenfeldt said. Interdisciplinary work across all the stages of academic life -- from undergrad to faculty.
