  For a class of wreath-like product groups with property (T), we describe
explicitly all the embeddings between their von Neumann algebras. This allows
us to provide a continuum of ICC groups with property (T) whose von Neumann
algebras are pairwise non (stably) embeddable. We also give a construction of
groups in this class only having inner injective homomorphisms. As an
application, we obtain examples of group von Neumann algebras which admit only
inner endomorphisms.
