Table 3

VEGF concentration (pg/mL) in calcium versus calcium and thrombin activated fresh and frozen/thawed PRP samples.

	Ca activated PRP VEGF concentration	Ca and thrombin activated PRP VEGF concentration	value
Fresh	545.2 ± 349	608.7 ± 494	0.695 (NS)
Frozen/thawed; (1 week)	339.5 ± 190	365.2 ± 189	0.743 (NS)
Frozen/thawed; (3 weeks)	339.9 ± 189	365.6 ± 188	0.741 (NS)

NS: not significant.
