Let Q be an acyclic quiver and let [Formula: see text] be the corresponding cluster algebra. Let H be the path algebra of Q over an algebraically closed field and let M be an indecomposable regular H-module. We prove the positivity of the cluster characters associated to M expressed in the initial seed of [Formula: see text] when either H is tame and M is any regular H-module, or H is wild and M is a regular Schur module which is not quasi-simple.
