PDGF-BB (pg/mL) concentration in every blood component cultured with either MSSA or MRSA at 24 hours.

Blood components	MSSA	MRSA
Platelet-rich plasma (PRP)	2330 (942.5)^a	2080 (1568.5)^b
Platelet-rich gel (PRG)	1723 (3305)^b	1904 (6577.5)^b
Leukocyte-poor plasma (LPP)	2163 (3520)^b	1746 (1613)^b
Leukocyte-poor gel (LPG)	2225 (2913.5)^b	3690 (3674)^b
Plasma	88 (616.5)^c	330.5 (894)^c
Heat-inactivated plasma (IP)	0 (0.5)^d	13 (183.5)

LPP + NID	1755 (806.5)	1755 (806.5)

Significantly different from plasma, IP (0.001), and LPP + NID ( > 0.05). ^bSignificantly different from plasma and IP ( > 0.001). ^cSignificantly different from IP ( > 0.05), PRP + NID, and LPP + NID ( > 0.001). ^dSignificantly different from PRP + NID and LPP + NID ( > 0.001). ^eSignificantly different from LPP + NID ( > 0.01). Significantly different concentrations for both bacteria in IP ( > 0.05). NID: nonionic detergent.
