    • The present invention discloses a biologically active basement membrane composition. When polymerized under physiogical conditions, the composition forms gel-like structures whose ultrastructure resembles interconnected thin sheets of the lamina densa zone of basement membrane. The major components of the composition include laminin, type IV collagen, heparan sulfate proteoglycan, entactin and nidogen. These components polymerize in constant proportions when redissolved and allowed to reconstitute. Molecular sieve studies on the soluble extract demonstrate that laminin, entactin and nidogen are associated in a large but dissociable complex. The reconstituted matrix is biologically active and stimulates the growth and differentiation of a variety of cells, including epithelial cells, nerve cells, hair follicles and the like. The reconstituted matrix can also be used for determining metastatic potential of tumor cells and for isolating metastatic tumor cells.
    • 本发明公开了一种生物活性基底膜组合物。 当在生理条件下聚合时,组合物形成凝胶状结构,其超微结构类似于基底膜层厚度相互连接的薄片。 组合物的主要成分包括层粘连蛋白,IV型胶原,硫酸乙酰肝素蛋白聚糖,内含子和核酸。 当重新溶解并允许重构时,这些组分以恒定的比例聚合。 可溶性提取物的分子筛研究表明,层粘连蛋白,内含子和内含子与大的但可离解的复合物相关。 重构的基质是生物活性的并刺激各种细胞(包括上皮细胞,神经细胞,毛囊等)的生长和分化。 重建的基质也可用于确定肿瘤细胞的转移潜能和分离转移性肿瘤细胞。
