Table 3 Concentration efficiency of growth factors in the PC supernatants at 3 and 12 hours

From: Evaluation of the effect of calcium gluconate and bovine thrombin on the temporal release of transforming growth factor beta 1 and platelet-derived growth factor isoform BB from feline platelet concentrates

Activating substance Variable Blood component  
PC-A (3 h) PC-A (12 h) PC-B (3 h) PC-B (12 h) PC-A+B (3 h) PC-A+B (12 H)
Calcium gluconate TGF-β1 (%) 42.86 44.32 46.54 45.95 89.40 90.27
  PDGF-BB (%) 61.36 55.46 60.61 54.69 121.97 110.15
Bovine thrombin TGF-β1 (%) 42.88 50.46 54.64 63.90 97.52 114.36
  PDGF-BB (%) 65.64 65.88 72.12 65.82 137.76 131.70
  1. TGF-β1= transforming growth factor beta 1, PDGF-BB= platelet-derived growth factor type BB.
