SDF-1α levels in human GCF in healthy or diseased patients. A) SDF-1α levels in diseased subjects were significantly higher compared to healthy subjects. Subjects who received manual mechanical therapy (scaling and root planing) demonstrated SDF-1α levels comparable to healthy individuals ∼6 weeks after treatment. SDF-1α levels in the GCF of human subjects were stratified by PD. B) Sites with CAL ≥5 mm demonstrated 56% more SDF-1α (76.4 ± 49.3 ng/μg) than sites with PDs <5 mm (32.77 ±21.1 ng/μg). *Significance at P <0.05.
