Generation of full-length cDNA recombinant vectors for the transient expression of human fibronectin in mammalian cell lines
In order to study the roles of the different alternatively spliced variants of human fibronectin (FN) as well as of its binding sites and structural domains in the processes of extracellular matrix assembly, cell adhesion, and cell migration, we constructed expression vectors coding for different hu...
