We consider quantum transition amplitudes, partition functions and observables
for 3D spin foam models within SU(2) quantum group deformation symmetry,
where the deformation parameter is a complex fth root of unity. By considering
\fermionic" cycles through the foam we couple this SU(2) quantum group with the
same deformation of SU(3), so that we have quantum numbers linked with spacetime
symmetry and charge gauge symmetry in the computation of observables. The
generalization to higher-dimensional Lie groups SU(N), G2 and E8 is suggested. On
this basis we discuss a unifying framework for quantum gravity. Inside the transition
amplitude or partition function for geometries, we have the quantum numbers of
particles and elds interacting in the form of a spin foam network
