Scientists were encouraged and challenged to use whatever pharmacological enhancers and genetic engineering tools they had at their disposal to move their cells through a fluidic maze faster than any other team.
A paper published in PLOS has collated the findings from the inaugural race, held in 2014. Fourteen teams participated in the races with cell lines supplemented to have increased speed and chemotactic accuracy.

The video shows the cells of the winning team, which had to have the highest amount of cells among the first 100 to cross the finish line. That group, the laboratory of Arjan Kortholt and Peter van Haastert, had modified their Dicty cells to have an increased activity of Ric8, a regulator of G-protein signaling. That change likely improved the cells’ ability to perceive the gradient, and made them able to both enter the maze more quickly as well as find the shortest path through it. Thus, the adage “slow and steady wins the race” remained true in this instance.

The ultimate goal isn’t just to have fun, however. The competition aims to eventually help enhance neutrophil migration under disease conditions by building upon basic fundamentals in model research systems. They have also not only demonstrated the feasibility of such a race but also provided suggestions for improvements of future contests.
