ICP/OES application for assessing cadmium uptake (or toxicity) in glomerular cells: influence of extracellular calcium.

The risks of metals for health are highlighted by their chemical stability and their persistence in the environment. Chronic exposure to low cadmium (Cd) concentrations results in renal dysfunction mainly. Cd has been regarded primarily as a renal tubular toxicant, but glomerular structures may also be affected.

Cadmium induces direct morphological changes in mesangial cell culture.

The cadmium produced by industrial and agricultural practice represents a major environmental pollutant which may induce severe damage, especially in the kidney where cadmium accumulates. While cadmium is known to severely impair renal tubular functions, glomerular structures are also potential targets. The present study investigated the effects of cadmium on glomerular mesangial cell cultures after short- and long-term exposures, requiring for each endpoint specific culture conditions.
