Collagen/Heparin Bi-Affinity Multilayer Modified Collagen Scaffolds for Controlled bFGF Release to Improve Angiogenesis In Vivo.

abstract：:In many industrial applications, inadequate cell attachment can be a limitation, especially when serum-free media are used. Nitrogen-rich plasma-polymerised ethylene (PPE:N) exhibits high concentrations of polar groups that can help to promote the attachment of weakly adherent cell types. Tissue plasminogen activator-...
