  We show how the fields and particles of the standard model can be naturally
realized in noncommutative gauge theory. Starting with a Yang-Mills matrix
model in more than 4 dimensions, a SU(n) gauge theory on a Moyal-Weyl space
arises with all matter and fields in the adjoint of the gauge group. We show
how this gauge symmetry can be broken spontaneously down to SU(3)_c x SU(2)_L x
U(1)_Q (resp. SU(3)_c x U(1)_Q), which couples appropriately to all fields in
the standard model. An additional U(1)_B gauge group arises which is anomalous
at low energies, while the trace-U(1) sector is understood in terms of emergent
gravity. A number of additional fields arise which we assume to be massive, in
a pattern that is reminiscent of supersymmetry. The symmetry breaking might
arise via spontaneously generated fuzzy spheres, in which case the mechanism is
similar to brane constructions in string theory.
