In vitro induction of hydrolytic activity in human gingival and pulp fibroblasts by triethylene glycol dimethacrylate and monocyte chemotatic protein-1 Gregson KS et al. - TEGDMA exposure induced the expression of monocyte chemotatic protein-1 (MCP-1) from the U937 cells. Both the cell lysates and conditioned media from the HGFs showed increased hydrolase activity after exposure to a sublethal concentration of TEGDMA. MCP-1 alone increased the hydrolytic activity and the combination of MCP-1 and TEGDMA was additive in HGF conditioned media. The DPFs were also exposed to MCP-1 alone and followed by a sublethal concentration of TEGDMA. The effect of MCP-1 was greater than that of TEGDMA. [more...]
