Let U be the quantised enveloping algebra associated to a Cartan matrix of finite type. Let W be the tensor product of a finite list of highest weight representations of U. Then End(U) (W) has a basis called the dual canonical basis and this gives an integral form for End(U) (W). We show that this integral form is cellular by using results due to Lusztig.
