All concentrations significantly increased cell proliferation on Day 1, 3 and<br />

5 <strong>of</strong> exposure in serum free conditions. Pb exposure resulted in dosedependent<br />

decrease in intracellular protein and procollagen I production<br />

over 5 days. In presence <strong>of</strong> serum only 4.5 H 10 −5 M significantly increased<br />

protein production. Pb significantly decreased osteocalcin production.<br />
