... of adhesive PEO domains presenting only RGD peptides. This confirmed that the observed effects were primarily the result of the differences in lateral spacing of the adhesive peptide and not the differences in adhesive peptide surface density. Fig. 2. Lateral spacing of RGD peptides affects hMSC...

..., we examined fertilization for two different hallmarks of integrin function, namely, dependence of ligand binding on divalent cations and the ability to inhibit ligand binding with RGD peptides. We demonstrate that sperm binding to zona pellucida -free eggs is supported by Ca 2+ , Mg 2+ , or Mn 2...
