Fig. 2From: The potential application of concentrated growth factor in pulp regeneration: an in vitro and in vivo studyThe effects of LPS on the expression of proinflammatory cytokines in hDPSCs. The release of TNF-α, IL-1β, IL-6, and IL-8 of hDPSCs after 1 (a), 3 (b), 5 (c), and 7 (d) days incubation of different dose of LPS were determined by qPCR. The results are mean ± standard deviation of triplicate measurements from three independent experimentsBack to article page
