Inhibition of hypertrophic scar derived fibroblast-populated collagen lattice contraction by calcium antagonist

AIM:In order to evaluate the possibility of using the calcium antagonist to treat hypertrophic scar contracture in clinically, we investigated the effect of calcium antagonist on the hypertrophic scar derived fibroblast populated collagen lattice contraction. METHODS: Having established fibroblast populated collagen lattice (FPCL) by culturing human hypertrophic scar fibroblast in vitro , we studied the effect of calcium antagonist on FPCL contraction. RESULTS: Six strains of fibroblast were isolated from human hypertrophic scar obtained from operation. Calcium antagonist, verapamil, could inhibit the contraction of FPCL by a does dependent way, but had no effect on the rapid contraction of FPCL. Morphological changes had also been observed. CONCLUSION: Calcium antagonist, verapamil, can inhibit the contraction of hypertrophic scar fibrolast populated collagen lattice. Calcium antagonist may play a vital role in the inhibition, which inhibits not only the changes of Ca 2+ concentration of the cell but also the collagen synthesis.
