Fig. 2From: Responses of promyelocytic leukemia HL60 cells as an inflammatory cell lineage model to silica microparticles used to coat blood collection tubesEffects of silica microparticles (MPs) on the surface microstructure of control and phorbol 12-myristate 13-acetate (PMA)-treated HL60 cells. The control cells A and those simultaneously treated with silica MPs for 3Ā days B were fixed and subjected to scanning electron microscopy examination. Similar data were obtained from two additional independent experiments (nā=ā3)Back to article page
