Dependence of the number of VSMC cells on the cultivation time for pristine PE (PE), PE plasma modified for 50, 150, and 400 s (50–400) and subsequently grafted with PEG (molecular weight M = 300 g/mol, 50–400/300), and PEG (molecular weight M = 20000 g/mol, 50–400/20000) and tissue polystyrene (TCPS) [11].
