RGD-containing peptide GCRGYGRGDSPG reduces enhancement of osteoblast differentiation by poly(L-lysine)-graft-poly(ethylene glycol)-coated titanium surfaces

Jeffrey Alan Hubbell

Osteoblasts exhibit a more differentiated morphol. on surfaces with rough microtopogs. Surface effects are often mediated through integrins that bind the RGD motif in cell attachment proteins. Here, we tested the hypothesis that modulating access to RGD bi ...
