Morphology and cellular composition of MuASCs evaluated on 7th day of culture; light microscope (a, f), staining for DAPI (b, g), DAPI/phalloidin merged (c, h), and SEM (d, e, i, j) images. Morphological features were indicated with proper abbreviations: fp: filopodia, lp: lamellipodia, and mvs: microvesicles. Magnification: DAPI ×50, scale bar: 250 μm; DAPI/phalloidin ×100, scale bar: 250 μm; SEM ×5000, scale bar 2 μm.
