Fig. 1From: 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 treatmentTopology of Ti implant surface, analyzed using SEM. Under × 10,000 magnification (a-d); under × 30,000 magnification (e-h). (a, e) Plasma-untreated Ti on which PBS was immobilized (N-PBS) implants, (b, f) plasma-treated Ti on which PBS was immobilized (P-PBS) implants, (c, g) plasma-untreated Ti on which SHED-CM was immobilized (N-CM) implants, (d, h) plasma-treated Ti on which SHED-CM was immobilized (P-CM) implants. Bars indicate 3 μm (a–d) and 1 μm (e–h)Back to article page
