Fig. 4From: The potential application of concentrated growth factor in pulp regeneration: an in vitro and in vivo studyEffects of CGF on the expression of proinflammatory cytokines in LPS-stimulated hDPSCs. Cells were cultured with or without 1× CGF in the presence of 1 μg/mL LPS for 1 (a), 3 (b), 5 (c), and 7 (d) days. The release of IL-6, IL-8, and TNF-α were determined by means of by qPCR (*P < .05, **P < .01)Back to article page
