to understand how the collagen receptors are involved in hela cell spreading on collagen we investigated the effects of divalent cations and arg-gly-asp-containing peptides on adhesion to gelatin , since hela cells behave similarly on both native type i collagen and gelatin substrata and also whether arg-gly-asp-containing substrata would substitute for gelatin in facilitating cell spreading .
