本实验利用组成细胞外基质的两种糖蛋白──纤维粘连蛋白和层粘连蛋白，以及来源于肝、肺组织的两种生物基质，在体外研究了细胞外基质对大鼠支持细胞的贴壁和铺展及形态的影响。结果证明两种糖蛋白均能促进支持细胞的贴壁和铺展。来源于肺组织的生物基质能在体外保留体内支持细胞的柱状细胞形态，而来自肝组织的生物基质则没有这种特性。 In this study, the extracellular matrix of two glycoproteins ─ ─ fibronectin and laminin, as well as from liver and lung tissue of two biological substrates in vitro study of the extracellular matrix of rat adherent cells And spread and shape of the impact. The results demonstrate that both glycoproteins promote the adherent and spreading of supporting cells. The biological matrix derived from lung tissue retains the columnar cell morphology of the supporting cells in vivo in vivo, whereas the biological matrix from the liver tissue does not have this characteristic.
