Fig 1: Phenotype characterization and inflammatory state evaluation of SV KL<3 and SV KL≥ 3 cells. a CD105, b CD90, c CD45, d CD73 antigen expression. Data reported as percentage of positive cells. qRT-PCR analysis of relative mRNA expression of: e IL-1β, f TNF-α, g IL-6 and h IL-8. Data reported as relative mRNA expression (2^ -∆Ct ) for experimental samples, normalized for β-actin. Student t test for each parameter (Mean ± SD, n = 6 duplicates), SV KL<3 vs SV KL≥3: *, p < 0.05; **, p < 0.005; ***, p < 0.0005
