Free calcium ions, as a kind of message-transport substance, is important in cellular activity such as cell movement, cell differentiation and cell proliferation. In order to investigate the relationship between free calcium ions and scar contracture, the fibroblasts which originated from hypertrophic scar, keloid and normal skin were used as the experimental target. The fibroblasts from 4th-6th generations of different sources were used; Then the intracellular free calcium ions concentrations were measured respectively by the fluorescent Ca2+ indicator Fura-2/AM and Image analysis system. The results showed that the level of Ca2+ in fibroblasts of hypertrophic scar was higher than that in keloid and normal skin (P  lt; 0.01). There was no significant difference between the level of Ca2+ in keloid and in normal skin. The conclusion was that the concentration of intracellular free calcium ions played an important role in the scar contract, but the exact mechanism was still unclear and required further study.
