Abstract: We present the study of the initial mass function (IMF) of embedded star formation regions located along the Perseus Arm. A survey of near-infrared observations (JHK-bands) provided information on 6298 stars in 40 young stellar clusters (YSCs). Cluster ages are estimated from theoretical models based on the observed J-band luminosity functions. Then, individual stellar extinction and masses are estimated to study the IMF in each YSC. Photometric limitations and extinction in each region lead to a stellar mass, Mlim, which defines the limit at which a sample of stars in a cluster is considered complete. The analysis of young stellar clusters in the Perseus Arm considering Mlim values leads to an IMF composed of three segments: Γ = -0.20 (0.3<M<0.6 M); Γ = -0.75 ± 0.10 (0.6<M<1 M); and Γ = -0.96 ± 0.14 (M>1 M).
