We demonstrate mesoscopic transport through electronic states in quasi-1D lattices maintaining the combination of parity and time-reversal symmetries by controlling energy gain and loss. We investigate the phase diagram of the non-Hermitian systems where transitions take place between unbroken and broken PT-symmetric phases via exceptional points. Electron transport in the lattice is measured only in the unbroken--but not broken--phase in the energy band. The broken phase allows for spontaneous symmetry broken states where the cross-stitch lattice is separated into two identical single lattices corresponding to conditionally degenerate eigenstates. These degeneracies show a lift-up in complex energy plane, caused by the non-Hermiticity with PT-symmetry.
