Much effort has been made in trying to solve or at least evade the inconsistencies that emerge from general relativity as the framework for a cosmological model. The extra-dimensional models rise as superb possibilities in this regard. In this work, I present cosmological solutions for Wesson's space-time-matter theory of gravity. A relation between mass variation at cosmological scales and the expansion velocity of the universe is obtained. Such a relation yields novel features on space-time-matter theory of gravity, which are carefully discussed.
