The influence of the cultivation substrate on the differentiation of ADSCs towards VSMCs. The correlation of relative mRNA expression of genes for calponin 1 (CNN1) and smoothelin (SMTN) in human adipose-derived stem cells cultivated in differentiation medium on standard tissue culture polystyrene (PS), PS coated with type 1 collagen (PS + Col) or with fibronectin (PS + FN). Measured by real-time PCR. Arithmetic mean ± SD from 2–3 samples for each experimental group and time interval. ANOVA, Student-Newman-Keuls method. Statistical significance: * p≤0.05 in comparison with corresponding control PS samples.
