Influence of the MI on cell–microcarrier aggregate size and cell proliferation. A Suspension and distribution of microcarriers in flasks at days 1, 5, and 9 of cultivation. B Microscopic brightfield images of cell–microcarrier samples on day 9. Scale bar = 500 μm. C Comparison of the frequency distribution of cell–microcarrier aggregate diameters before and after impeller modification. Red: original impeller (OI), blue: modified impeller (MI). D Cell proliferation curve before and after paddle leaf modification
