We explain physically the observation of Tanaka and Araki[Phys. Rev. Lett. {\bf 85}, 1338 (2000)] of hydrodynamic stabilization of cellular network structures in two dimensions. We demonstrate that hydrodynamic interactions have only a minor quantitative influence on the structure of transient gels in three dimensions. We discuss some experimental implications of our results.9 pages, 6 figures. Contact K. Miyazaki for figures with better resolutionsSoft Condensed Mattertext
