  • Peptides promoting cell adherence, growth and secretion
    Publication number: 20030162289
    Abstract: The present invention provides specific peptides identified as having cell adhesion, growth, expression or secretion-enhancing activities. Many of the peptides of the invention may be produced in large quantity by such means as chemical synthesis or recombinant DNA methodology. They may be non-specifically adsorbed, or chemically attached to a surface or, alternatively, formulated in a culture medium to produce the desired effect on cultured cells.
