FN1 and sarcoma: For this purpose, cell culture vessels were coated with murine proteins secreted by Engelbreth-Holm-Swarm (EHS) sarcoma cells (Geltrex, 45 μg/cm2), human recombinant Vitronectin (1 μg/cm2), porcine gelatin (1 μg/cm2), human recombinant Laminin-511 (1 μg/cm2), human recombinant Laminin-521 (1 μg/cm2), human fibronectin (0.5 μg/cm2), human recombinant Collagen I (5 μg/cm2), human Collagen IV (5 μg/cm2) and fractions of laminins isolated from EHS tumour (1 μg/cm2).
