Abstract

Cytotoxicity (MTT test) and cell viability (CFE) along with the metal intracellular accumulation were studied in human HaCaT keratinocytes challenged with nickel, cobalt or chromium within a SCA project entitled "Indicators of metal sensitisation". ED50 values were calculated, being Cr(VI)<Co(II)<Ni(II). Metals accumulated mainly in the cytosol, the percentage being Ni(II)>Co(II)>Cr(VI), and were concentrated with respect to the external dose 30, 9,5 and 400 times, respectively, These findings are discussed in relation to the cytotoxic mechanisms underlying metal-induced allergic contact dermatitis.
