We have observed the starburst galaxy NGC 253 using the Karl G. Jansky Very Large Array. We present evidence for entrainment of star-forming dense-molecular gas in the outflow of NGC 253. We also show that H2O masers are associated with forming super star clusters and not with supernova remnants. We detect four new 36 GHz CH3OH masers in the central kpc and show possible evidence for a star-formation origin of two class I CH3OH masers. Such high resolution observations are essential for understanding the origin of these masers.
