We present several regularity results for a biological network formulation model originally introduced by D. Cai and D. Hu [13]. A consequence of these results is that a stationary weak solution must be a classical one in two space dimensions. Our mathematical analysis is based upon the weakly monotone function theory and Hardy space methods.

Keywords: $ A_q$-weights, biological network formulation, bounded mean oscillation (BMO), weakly monotone functions.
