Neutral pion production measured with the ALICE detector in Pb-Pb collisions at the LHC is an important tool to study the properties of the hot and dense medium created in heavy-ion collisions. The neutral pion yield, obtained with the ALICE electromagnetic calorimeter in pp collisions at sqrt(s) = 2.76 and 7 TeV, as well as in Pb-Pb collisions at sqrt(s_NN) = 2.76, is analyzed in terms of x_t scaling. High-p_t neutral pions are used as trigger particles to study the momentum distribution of the associated charged particles. The latest status of the analysis in pp and Pb-Pb collisions will be presented.
