Fig. 6: Stem cell cultivation and maintenance of mESC stemness.

a Quantification of time-dependent mESC growth on various substrata, normalized to data obtained from mESC on PLL for 4 h (red dashed line). All data are represented by mean ± S.D. of triplicate samples. b Representative fluorescence images of immunostained mESCs grown for 4 days on gelatine-coated PLL in the absence (upper row) or presence (middle) of LIF or on S100 in the absence of LIF (bottom).
