Effects of mycotoxins in cultured kidney cells: cytotoxicity of aflatoxin B1 in madin-darby and primary fetal bovine kidney cells
The cytotoxicity of aflatoxin B1, a fungal metabolite and an important food contaminant, was evaluated in an established cell line, Madin-Darby bovine kidney (MDBK) cells, and in primary fetal bovine kidney (PFBK) cells.

Summary: | The cytotoxicity of aflatoxin B1, a fungal metabolite and an important food contaminant, was evaluated in an established cell line, Madin-Darby bovine kidney (MDBK) cells, and in primary fetal bovine kidney (PFBK) cells. Cells were grown in monolayers and treated with media containing AFB1 for 24 hr. Both culture systems were sensitive to the chemical; the PFBK cultures were approximately four times more susceptible to the cytotoxic effect. Cell multiplication decreased in both systems in long-term cultures. Adherence of MDBK cells was only slightly reduced at the toxic concentrations of the chemical. Electron microscopy revealed condensation of chromatin, separation of nuclei from the cytoplasm, cytoplasmic vacuolization, and loss of surface microvilli. Results indicated differential sensitivity of the two culture systems. |
