它是以前证明,基质来自分化良好的结肠癌细胞系诱导一个更良性的程序在一个单独的恶性结肠癌细胞系,MOSER AF。本研究试图定义的作用,细胞外基质成分的生物事件的MOSER AF细胞。形态学的变化,分泌癌胚抗原(CEA)和尿激酶所带来的个别成分进行了测定。层粘连蛋白诱导类似的变化,结肠来源的基质中,有增加的细胞附着和扩散,4倍的CEA升高和尿激酶减少45%。纤连蛋白刺激细胞附着而不改变形态,并减少纤溶酶原激活物的量。然而,CEA值保持不变。MOSER af细胞在所有类型的胶原蛋白上的生长未能引起细胞形状或CEA的任何变化。然而,I-III型胶原蛋白使尿激酶水平提高了40%。转化生长因子β(TGF-β)诱导细胞层粘连蛋白和纤连蛋白,促进细胞附着和铺展,升高CEA并减少尿激酶。这些数据表明,层粘连蛋白和可能的纤连蛋白在更成熟的结肠细胞的生物学事件中发挥作用。
It was previously demonstrated that substrata derived from well differentiated colon carcinoma cell lines induced a more benign program in a separate malignant colon cell line, MOSER af. This study attempts to define a role for extracellular matrix components in the biological events of MOSER af cells. Alterations in morphology, secreted carcinoembryonic antigen (CEA) and urokinase brought about by individual components were determined. Laminin induced similar changes to colon-derived substrata in that there was increased cell attachment and spreading, a 4-fold elevation in CEA and a 45% reduction in urokinase. Fibronectin stimulated cell attachment without altered morphology and reduced the amount of plasminogen activator. CEA values, however, remained unchanged. Growth of MOSER af cells on all types of collagen failed to elicit any change in cell shape or CEA. However, type I III collagen raised urokinase levels by 40%. Transforming growth factor β (TGF-β) induces cellular laminin and fibronectin, promotes cell attachment, and spreading, elevates CEA and diminishes urokinase. These data argue for a role for laminin and possibly fibronectin in the governing of biological events culminating in a more mature colon cell.
