Figure 6. Changes in basal ATP secretion from human platelets immediately after (within 1 min) and following 15 min incubation of the platelets with either HNPs, BNPs or HA crystals at two different doses: 50 NTU and 150 NTU.

Figure 6

ATP secretion is presented as percentage change compared with vehicle-treated controls. Data are mean ± standard error of the mean of triplicate determinations on paired samples of blood (n = 5–7).

*Significantly different (p < 0.05) by paired t-test from corresponding value in untreated control.

‡50 NTU of the same treatment.

BNP: Bovine-derived nanoparticle; HA: Hydroxyapatite; HNP: Human-derived nanoparticle; NTU: Nephelometric turbidity unit.
