Quantification of protein derived from SHED-CM by using APP pretreatment. Silver staining of proteins separated by SDS-PAGE. Proteins immobilized on titanium powder (N-CM and P-CM) were extracted using 4 M guanidine (a). Results of the Bradford protein assay (b). Data from panel (b) are presented as mean ± SD (n = 3). *P < 0.05, **P < 0.01. M Marker, N-CM plasma-untreated Ti on which SHED-CM was immobilized, N-PBS plasma-untreated Ti on which PBS was immobilized, P-CM Plasma-treated Ti on which SHED-CM was immobilized, P-PBS Plasma-treated Ti on which PBS was immobilized
