SDHI Pesticides Are Toxic for Human Cells (IMAGE) CNRS Caption A and D: control human cells (fibroblasts) cultured for ten days in the presence (A) or absence (D) of glucose, with glutamine being the only source of carbon in this final condition. B and E: cells cultured in the presence of bixafen 1 μM. In image E, in the absence of glucose, there is the presence of numerous white stains indicating the presence of dead cells. C: despite the presence of bixafen 20 μM, no sign of cellular suffering was observed in the presence of glucose. F: the absence of glucose led to massive cell death, with a concentration of bixafen as low as 5 μM. The black line in each figure represents a scale of 200 μm.
