We present the stellar population analysis using MUSE optical spectra of the spiral galaxy NGC 628 and find that current maximum star formation in spatially resolved regions is regulated according to the level of star formation in the recent past. We propose a model based on the self-regulator or "bathtub" models, but for spatially resolved regions of the galaxy. This model allow us to estimate the mass-loading factor. We present the application of this model to more galaxy discs observed with MUSE, and compare mass-loading factors with different properties of the galaxies.
