Fig. 4From: A new application of cell-free bone regeneration: immobilizing stem cells from human exfoliated deciduous teeth-conditioned medium onto titanium implants using atmospheric pressure plasma treatmentQuantification 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.
